Where is the flasher for the signal lights on a 1995 S10 Chevy Blazer?

It's behind the panel to the left of the cigarrette lighter. You need a Torx 25 screwdriver and another screwdriver for those hex shaped screws, forgot the size. First unscrew the 2 Torx 25 screws beneath the steering wheel. Then unscrew the rest of those Hex screws on the bottom. The panels overlap, so be prepared for a lot of unscrewing. You do need to unscrew the middle black panel on the bottom, right beneath the cig lighter. It's held by two Hex shaped screws, one on each side and are hard to unscrew. Also you need to remove your spare change sliding tray to unscrew the last hex looking screw. Once you pop your panel off, the turn signal flasher is the right one. The Hazard flasher is the left one. You can find a replacement part at Autozone, and DON'T get the $184 Flasher switch, all you need is the signal flasher. It's shaped like a cylinder with TWO prongs on it.

Why do tires lose air pressure?

Rubber is actually somewhat porous. A few pounds a year are normal. The number one cause of air loss is usually rim leaks that cannot be seen. Spray soap water solution around the rim to see them. Most tire places will not clean the rim properly when they mount tires and rely on rim sealers that sometimes don't work. On an older car, the rims get rusted in the bead area and need sanding and buffing to seal properly.

How do you download a torrent?

First, you need to have a Torrent program on your computer. Some programs are Vuze and uTorrent (which is the smallest, but most reliable Torrent program). Then when you want to download something, either type the name in the search box, or go online to a Torrent downloading website and search around.

55 watts is how many volts?

A Watt is a measure of power not voltage.

Voltage X Amps = Watts (in a DC circuit)

If you have a 55 watt light bulb for a car and you are looking for the amperage:

55W/13.8v = 3.99Amps (a typical alternator charging voltage is 13.8v)

4 volts is a many watts?

4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts...

See Ohms Law: Watts = Volts x Amps

If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts.

If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.

You have 1 12 inch 4 ohm 400 watt rms sub and an amp that will push out 500 watts rms at 2ohms and 300 watts rms at 4 ohms will this amp be sufficent enough for the sub?

If your subs are 4ohms each, then yes it'll be easy. Hook them up in parallel and you're up and running at 800W! :) I would recommend that you purchase an amp capable of more than 800W x1 @ 2ohms though. My basic rule of thumb is that the amp should be approximately 30% more powerful than the speaker(s). This is to help ensure that you're not feeding the speakers distorted sound. Distortion is the enemy of voice coils(and usually the cause of premature speaker failure). So, 800 x 1.3 = 1040. I would recommend an amp capable of at least 1000W x1 @2ohms.

How do you use the aux on a Pioneer Mosfet 50wx4?

Turn off the player, hold down the function button until it turns on taking you to a menu letting you set the time etc.

Keep pressing the function until you get to the aux option, turn it on by pressing the up key.

Then start the unit and press the mode button, you should now have CD, Tuner and Aux available.

What are fuses?

A fuse is a safety device that lies in series in a circuit between an electrical source and its associated load(s). When the current, or flow of electricity, exceeds its designed threshold, the fuse is calibrated to permanently open the series circuit, thereby disconnecting the load(s) from the power source. Unlike circuit breakers, which can be reset to allow current to flow again, once a fuse disconnects, it must be discarded and replaced with a new fuse.

Fuses protect a circuit from overheating due to excessive current flow. Wires and components are designed to carry up to a certain amount of current, and if the flow of current exceeds that design limit, the wire or device could overheat. Unprotected wires and electrical devices can get so hot that they can catch fire, or heat adjacent materials to their combustion point, thus starting a fire in those adjacent materials.

Modern houses are most commonly equipped with circuit breakers, not fuses, for the house wiring. Fuses are still commonly embedded in vehicles, electrical devices, and electronic components.

A fuse is usually constructed using a thin metal strip or filament encased in a protective transparent glass or plastic enclosure. Each end of this metal strip is connected to a separate terminal on the outside of the fuse, and these external terminals in turn connect to matching terminals attached to the circuit being protected. All the electrical current that flows through the circuit passes through this single strip of metal inside the fuse.

The metal strip inside the fuse is designed to overheat and melt if the current exceeds the fuse's rating. When this metal melts away, the strip is broken, and there is no longer a path permitting the current to flow, and therefore the fuse disconnects the electrical circuit. We commonly describe a fuse as being "blown", or we say the fuse "blows" when it disconnects the electrical circuit.

Fuses are available in pre-defined ratings, such as 1 Amp, 5 Amps, 15 Amps, 25 Amps, and so on, and these ratings are clearly indicated on the fuse. Many fuses are also color coded to simplify the rating identification. The transparent enclosure permits visual inspection of the metal strip or filament, so you can see if the fuse has blown.

It is important to turn off or disconnect the electrical load(s) that caused a fuse to blow, because if you leave all those electrical devices turned on, then the next fuse will also blow as soon as you replace the first one. It is also very important to replace a blown fuse with good fuse of exactly the same rating. You should never, for example, replace a 15 Amp fuse with a 25 Amp fuse, because then the wiring is no longer properly protected, and it could overheat and cause a fire.

It is important to distinguish a fuse from a Ground Fault Interrupt (GFI) safety device. A fuse will not prevent death by electrocution. Nor does a fuse protect against fire due to arc faults. The fuse's only purpose is to protect against excessive current flow in a circuit. Like it's dynamite!

Where is the turn signal flasher on a 2000 Chevy blazer?

everyone should have a manual for their vehicle, and the library should have a professional manual available...in the reference section, you'll have to make copies of the important sections...good luck :)

How do you reset check engine light on 2003 4.3 blazer?

The check engine light is illuminated for a reason. One of the engine control devices has probably ceased functioning. Take the vehicle to a shop for diagnosis, and repair of the problem.

What are the impacts of computers on environment?

I belive some computers add to the incessant increase of pollution in terms of garbage and such. However, it also has positive effects such as the innovation it brings in protecting and preserving the environment.

What is ICDP switch?

ICDP Stands For Iron Clad Double Pole. It is also known as Main Switch. It contain two fuse. One is for phase wire and another is for neutral wire.

What do you use DC electricity for?

Direct current (dc) electricity is used in many different things, including for example: digital watches and cameras, cellphones, laptop computers, mp3 players, cars, motorbikes ...

Why do you have relays?

to control a high-current circuit with a low-current signal for example a starter on a car uses a very high current (not voltage) and needs thick cable to provide it.
it would be impractical to run this thick cable up to the ignition key so a lower current from the starter key operates a switch, usually electro magnet, which in turn completes a circuit for the higher current.

How many watts can be powered by a 9 volt generator?

There is no way to answer without knowing the wattage rating of the 9 volt generator. A generator's wattage rating depends on the size of the wire in it, the wattage of the rectifiers if it is a DC generator, and the horse power of the engine or motor that is available to turn the generator.

How many amps does 1500 watts equal?

It all depends on the supply voltage. In the UK the supply voltage is 240V therefore the amps would be 1500w/240v = 6.25A. In the USA (with a supply of 110v) the amps would be 1500w/110v = 13.64A. All you need to remember is the formula 'amps = watts/voltage'

How many watts does 100 ohms equal?

Need the voltage or current of the circuit. And the type of lamp (bulb)--is it incandescent, fluorescent, LED, discharge?

Also need to know the temperature--the resistance of a tungsten filament changes by a very large amount from ambient temperature to hot/operating temperature.

What is the function of a rectifier within an alternator?

A rectifier turns the Alternating Current (AC) produced by the Alternator into Direct Current (DC) that your car uses.

What is the difference between an Inverter and a Converter?

The term converter usually refers to a DC to DC process where a higher or lower voltage is required. Even when a lower DC voltage is needed, it is sometimes more efficient to use a chopper style process rather than a voltage regulator. Converters are often used to condition dirty or highly variable sources like automotive, aircraft, and marine 12VDC systems into a very clean source of power for sensitive electronics. Many converters have very wide input voltage requirements that allow one design for a wide range of power 8-36 volts or more is not unusal. So you can operate even on almost dead batteries, or on a 24-36 V system without modification.

Inverter is a term that implies making AC from DC as in 12VDC input, 120VAC output.

This Is the correct answer:

DC (batteries) 12v to AC (house) 120v Inverter

AC (house) 120v to DC (batteries) 12v Converter
