You thought your battery died you boosted your car for ten minutes started driving and your car slowly turned off in the middle of the street at a stop light What does this mean?

There is a good chance that your alternator has stopped working. It could also be just a loose wire from the alternator to the battery that is not letting the battery charge.

Also it could be a bad battery. When a cell in a battery dies it will hold a charge for a short period of time but then rapidly die. Get the battery checked first. they the wires, then the alternator.

How do you replace the alternator on a 1998 Chevy S-10?

Disconnect the battery then remove the fan shroud. Release the tension on the belt and pull it off the alternator pulley. I use a ratchet with a 3/8" drive inserted into the tensioner pulley for leverage, but I believe they have tool or pry bar for this. The alternator has three bolts keeping it attached, the two on the front are pretty easy to see and remove. On the back side of the alternator is a bracket attching it to the block. There is one bolt (don't remember what size) which is rough to get out. I was able to use a ratchet and deep socket to remove it. ONce I finally got it loose, I disconnected the wiring. Installation is the reverse!

Is possible to short out the alternator while working on car?

The alternator really can be shorted out but you can cause a short if you contact the hot battery connection to ground. whenever you work on a car, you should really disconnect the negative battery cable. It takes that battery out of harms way and you too.

How do you change the alternator on an 88 300zx?

Somebody else may have a better way but I found it was easier for me by taking the two screws from the coolant reservoir and lifting it up out the way (without disconnecting), removing the bolts from the power steering pump (without disconnecting) and lifting it out of the way. Then remove the fan shroud. This will allow you ample room to get to and remove the alternator (which is located underneath the power steering pump). "GOOD LUCK"

What cause an alternator to blow?

The usual cause of a blown alternator is overload. The alternator will also blow if the battery is connected backwards, even for an instant, such as during jumping. Sometimes, overload is caused by attempting to jump start another car while revving the engine of the first car. The alternator is not designed to carry the current of a starter. Depending on the alternator, protection might be built in, but don't count on it. Rev the engine only to help charge the other battery, and then let the engine idle while starting the other.

Where is starter on Nissan Sentra?

the starter is connected to the bellhousing (the part of the transmission that connects to the engine) and sits above the tranny but on the fire wall side.

October 2007. This answer is incomplete. The bolt heads to unbolt the starter on the Sentra are located on the left side of the engine under the air cleaner and air inlet housing to the fuel injector intake. These housings must be removed to access the bolts heads, and then the starter is taken out from under the car on the right back side of the engine. The hardest part is disassembly of the intake housing to get to the bolt heads for starter removal.

How do you replace the alternator on a Oldsmobile Delta 88?

It's simple actually. First disconnect the alternator. There is a connector that you have to unhook. There are only three bolts holding that thing on. The toughest part is putting the belt back on. I'm female and could do it myself! It is very easy to change. The nut on the tension pulley is a 15mm I do believe. Put a ratchet on there and use a "cheater bar" for leverage to pull the tension pulley back and the belt slips right on real easy.

What if you change the alternator and battery and the Saturn still wont crank?

Freshly charged battery and good alternator...that usually means a bad starter. Check the following:

  • Poor ground connection-do the lights come on bright? ...does the horn work?
  • Starter relay is bad (AKA "The Solenoid") ...it could be that the starter had a bad solenoid from the factory or the rebuilder. Does the starter click? If you have a good charge but the starter doesn't click, it is probably the solenoid.
  • The ignition switch may be bad. Do you get power to the starter? You'll need a volt meter.
  • The neutral switch may be bad. That is the switch on the transmission that keeps the starter from running while the car is in gear. You can jumper that switch at the plug and try to crank it but be sure that you have the drive wheels off the ground or the car in park because it could start up and run over you. That hurts.
  • The starter may be bad...and they are the dickens to take out. Troubleshoot everything else, first.

I really kon't know why you are having a problem. Get a manual on your car from the parts store.

I had this issue when replacing my alternator. My best solution was to remove the wheel and the cover to get to it, this will also come in handy putting the surp. belt back in place and it's pretty difficult with the serp tool. coming from the top.
