Can you run a 5000 btu AC with a ProForce 2500 generator by Coleman?
Hi:
You got a bonifide good question on your hands there. No kiddin, And , A good question deserves a good answer. This, Is something I'm going to attempt to do for you.
- 1,,, lets for a moment, ( assume ) that the Coleman generator that you call a ProForce 2500 is in fact a
2500 watt rated generator at lets say,,, 115 V.A.C. 60 cycle and that none of this output ability is divided say amongst several various plugs you can choose from at the generator output. So again,,,, we are ( assuming stuff ) like,,, 115 volt 60 cycle single outlet 2500 watt max. output rating for your generator. By the way ::: I hate assuming stuff , K , it not good design criteria. A good saying is, You are only as good as your information you have to work with. BUT:::: bye golly !!! I do like your question.
- 2,,, Look at the tag on your A.C. and see if you are dealing with say 115 volt A.C. 60 cycle current in the first place. ( Probably is, But!, Make Sure! )
- 3,,, Look at the tag on your generator and do the same as
you just did in step 2.
- 4,,, You probably wont be lucky enough if your like myself
and see the wattage consumption plainly written anywhere on your A.C.. So look for something on there that indicates amps usage. basically, you know it'll be somewhere below 15 and almost certainly less than 20. There are reasons for this such as, design critirea that the A.C. must meet to be passed by government codes and to get U.L. approval. ( U.L. = Underwriters Laboratorys ) it is pretty much a mandated minimum requirement which has to be passed for electrical devices to be sold here in the U.S.A. Once again ( Assuming ) you are in the U.S.A.,, LOL Repeat procedure with the generator.
- 5,,, 2500 watt pretty well in its simplest form ,, ( I
said simplest form!!!! K,, ) don't go nailing to a tree alright. Again in its ( simplest form ) 2500 watt rating on the generator will mean roughly 25 Amps rating with a pure resistive load. Resistive is the key word here K. What you have with your A.C. is something a wee bit different. It's basically what is called a ( inductive load ),,, which is basically saying it is a motor you pluggin into that thing. This does complicate things a bit, However, we not going any deeper on that.
- 6,,, Look and see if that generator has a maximum surge
current rating. And also a duty cycle, which is basically how much work it can do as compared to its maximum rating. A wee bit of a rule of thumb,,, The total A.C. load ( all its power pulling components combined ) should not be more than 25% of the surge current rating and definetely not more than the continuous duty cycle rating for the outlet you are plugged into for your voltage requirement on your generator.
- 7,,, There are yet still other things to take into account
when designing around generators, ( But !!! ) we gonna keep it simple as possible. Your generator will probably operate the A.C. in question. But you may see that it runs into a bit of trouble when the A.C. cycles on and off. This is that inductive thing at work against you. You see,,, A inductive load can pull many times its rated running power rating in amps at start up.
Answer simplified: You cuttin it thin, and I don't think the Coleman Co. would be to comfy with this minimal margin for that particular generator. To be certain though, Call em up and ask them the same question you just asked me. Hopefully they'll have a toll free number for you to use, Cuz it might take awhile.
Jimiwane question. Running a A/C on GeneratorA 18 cf refrigerator uses 600 watts of power. Should be no problem running your ac
An A/C load is different than a one from a refrigerator...
you can 'run' the small 5,000 window unit (3 or 4,000 btu even better, LG makes a 3,000 unit...) with a small genset, even down to about 1kw or a bit more. the problem is, as stated above, the start cycle of the compressor unit needs a lot more 'headroom' than the smaller a/c units can generate (usually). you will wear the little a/c unit out pretty quickly. however, if you're going camping and need the thing for a week or so, by all means go for it. caveat: be careful of using a.c. (alternating current) where it rains, as you don't have any gfci (ground fault circuit interrupter) protection out in the woods! or the lake!!! BE CAREFUL! you'd be better off using a truck bed camper with a room window a/c unit in the front of the cab, stuck out one of the side windows with the cab to bed partition window open to allow air into the bed, using a little plug-in fan to direct the air to you in the bed/camper area. i know. I've done it. it works. at least you have the chassis ground to protect you that way. you'd still need to provide some cover for the genset if it rains though. if you're just looking for an a/c standby at your house, then it'll work, but again the start-up cycling will wear the unit out a lot faster than if it was plugged into an a.c. grid. a Yamaha or Honda is a great choice, as the inverter nature of the unit helps immensely with the problems I've outlined above. that comes at a price though. can't have it all - yet. I'm sure something's on the way...
How do you replace the alternator on a 1988 Toyota Tercel?
disconnect negative battery tml.,remove the plug from the alternator,remove the main battery wire from the stud on the alternator, remove the lock bolt, swing alternator down to remove belt, remove pivot bolt, swing alt. until its out. replacement is reverse of remova;
To take out the alternator on a 88' tercel, you have to do it from under the car
Every time you disconnect a battery cable you have to reprogram the radio
stations ( if that's what you are asking )

Remove pulley belt.
Disconnect battery.
Remover main electrical connector from alternator.
Remove one wire electrical connector from alternator.
Remove 3 or 4 bolts from alternator.

How do you test an alternator with external regulator?
Leave battery lead to alternator connected, disconnect other leads. Run car and check output at these two leads. Should be 14-16 Volts.
How do you replace the alternator in a 2001 Oldsmobile Aurora 3.5L?
This is not a simple repair, however it just takes time. You need to remove the cross member covering the radiator and then remove the radiator cooling fans. There is a retaining clip on the passenger side near the bottom that must be removed to free one of the transmission cooling lines (I believe).
The instructions say you need to remove the AC compressor - however I was able to remove the alternator without doing this. It is a VERY tight fit but it is possible.
Probably took about 4 hours to do the whole thing. The GM service guide was a help.
How do you replace the alternator on a 2000 Ford Focus?
Here is a better way. Instead of removing the engine mount, just slide the fan housing (holds the two electric fans) out of the way. You only have to thumb the two top clips open (no tools required), then lift the housing from its lower supports and slide it several inches away from the alternator (really easy to do). This allows plenty of clearance to remove the alternator and replace it. I changed out the alternator on our 2000 Focus in under an hour. Just replaced mine last week. The hardest part is once the alternator has been disconnected from all its mechanical and electrical connections. It won't come out unless the passenger side engine mount is unbolted ( 3 bolts, 19 mm I think ) and the engine is pried forwards. Once this was done, it was pretty easy. Don't forget to remove the negative battery terminal before starting.
What happen when alternator goes bad?
Your battery charge will get so low eventually car won't start and you will get stuck somewhere.
How do you wire an alternator?
Usually, these things are made so you can't mess it up by "keying" the connection. I'll assume the connection is broken since your asking. the positive (+) output (usually red) is plugged to the Positive side of the automotive circuit and the Negative (-) output (usually black) is connected to chassis ground or the negative side of the automotive circuit.
If its not clear what side is positive and negative, you should take it to a professional that will do a good job and has more knowledge.
Where is the fusible link for a 1988 jeep wagoneer alternator?
In the engine compartment, passenger side, on top of the wheel well hump closer to the firewall is where it ends, follow the wires coming off of the alternator, you will have to remove the wires from the wire loom, the wire will be connected with a thick rubber insulation on either side of the fusible link(the words 'fusible link' will be printed on the side of the fusible link wire) then it has an eye end and is connected to a single connector panel with a few other wires this is all on the wheel well.
What is the voltage of a cell in a lead-acid battery?
Each cell of a modern lead-acid battery should have an average voltage of about 2 volts but, depending on the cell's condition and state of charge, the exact voltage at any time may be somewhere in a range from about 1.8 volts (when it is almost fully discharged) and 2.25 volts when it is fully charged.
What?
9 out of 10 it will be a bad earth look for a strap from the engine to the body add a new one if you want !
My AnswerBatteries go dead because there is an electrical draw on them. And even a brand new battery can be faulty.Steps to track down the problem:
- Check the battery: disconnect and fully charge leave alone for an amount of time it would usually go dead in and recheck
- Reconnect your good battery to the car, now you need to go low tech or high tech
High tech
- Hook up you ammeter and check the draw on your battery it should settle down to about .01 amps but as high as .3 amps could be considered normal depending on alarm, stereo type and age of car etc. A 0.5 amp draw will kill your battery in a week or so
- Start removing fuses and check after each one to see if the draw falls noticeably Don't forget alarm and stereo amp. Once you know what the draw is you will need to repair the faulty item.
Low Tech
- Remove the fuses, using a test light between your positive battery terminal and the positive cable start plugging them in, what is killing your battery should get you test light to light even just dimly.
How to Install alternator on 99 Chevy Cavalier Z24 2 4 Liter?
Disconnect the battery.Jack the car up and place on stands. Next, place a board on the jack and jack it up until it's tight under the oil pan. Starting on the passenger side of the car, locate the AC lines. You'll notice they are secured to a upper motor mount. Remove the nuts holding the clip in place. Next remove the remaining nuts UNDER the previous ones.Remove a 10mm screw holding the coolant reservoir just behind the headlight. Now tilt towards the engine and lift carefully, and place out of the way. Remove remaining nuts to remove what's left of the upper motor mount. Now being sure the jack is still in place, remove the 2 large bolts that connect the outer half of the mount with the motor half of the mount. At this point the motor should start shifting around. BE SURE THE JACK IS STEADY!
Now remove the belt by releasing tension on the tensioner/ idler pulley. There are three bolts holding the Alternator in place. 2 go in from above and one from the side where the belt just was. Once removed the alternator will need to be unplugged by A) a wiring harness and B)a 13mm nut (red wire).
"Dance" the alternator out of it's current position and have it tested. NEXT, have the NEW ONE TESTED ALSO!!! If your battery is dead, BUY A NEW ONE!! The alternator WILL NOT charge a dead battery. Rather, the dead battery will destroy the internal diodes of the new alternator, forcing you to buy ANOTHER alternator. NOT FUN!
Wire up the new alternator, bolt it in place, re-attach the fender-half of the upper motor mount first, then line up the engine (rock it back and forth if you have too, being sure it stays on the jack)mount with the fender mount and bolt in the last remaining bolts.
This ISN'T the easiest thing to do by yourself. A second STRONG person should assist you.
Good Luck!
How do you wire the alternator to a battery?
It depends on the alternator.
The larger B+ goes to the battery (or starter)
The other wire goes to a globe then to the ignition switch (+). Early alternators the globe was a vital part of the circuit. Later ones it is just an indicator. Alternators with more connections have external regulators, track down a proper diagram.
BE aware : Some alternators will blow up if the B+ is disconnected whilst the engine is running
What is this dashboard symbol?
A small yellow symbol lit up on my dashboard, is it the transmission light?
How do you replace the alternator on a 1996 Chevy Lumina?
1. Disconnect the battery
2. Place a socket wrench in the belt tensioner and turn it up. This lets you slide the belt off of the alternator.
3. The alternator is held on to the engine with four bolts which need to be removed.
4. On the top of the alternator you will see a wire plug. Remove the plug and loose the bolt that is holding it in place. Then simply remove the alternator.
This is pretty easy. I am far from a mechanic but it only took me five minutes to do this.
Is there a diagram for putting on the alternator belt on a 1995 Lincoln Continental?
it should be located on the hood or in the engine compartment. if still no luck then got to you local dealer and they can provide a diagram for you
Why are horror stories so popular?
They carry a particular amount of interest that a lot of people desire and/or crave.
loosen the nut on the idler pulley. There is a bolt at 10:00 o'clock from the pulley.
Loosen this bolt until you can put the belt on then tighten the bolt till the belt is tight then tighten the nut on the idler pulley. Recheck the belt tension after a day or so..
