Make sure you have power to the post with the 10mm nut on it.If you do then you only need to have power to the "L" terminal to make it charge.If you don't have power either replace the bulb in the dash or run your own keyed power wire to it.

My truck wont charge and the alternator is good,could it be a wiring problem like a fuseabile link

Hi check the earth wire at the battery and also the wires to the rear of the starter motor and altenator, make sure they have good contacts and are not touching each other. also make sure the main battery earth wire has a good contact to the body.

It sounds like the altenator is charging but the charge is not getting back to the battery. make sure the altenator belt is tight.

Im not 100% if this model has a fuseable link, bt your along the right lines something is not connecting somewhere.

I have found this fault is most commonly a melted wire but they can be difficult to find. Sorry I couldnt be more specific. It is difficult without seeing the car.

Truck wont start even after it has been on the

Time for a new battery. Most places will test your battery for free. Expect to pay about $100.00 for a new battery for your truck.

My honda prelude stalled an now the stater is makins a funny nois and the moter wont turn over wat do i do

sounds like you have a dead battery and possible a bad altenator have the battery checked out and replace if bad. If not recharge and if the car starts have the charging system checked out you may have a bad altenator or voltage regulator probably built in the altenator. Possibly the starter but not likely since it stalled while running.

1997 chevy 1500 wont stay runing

Ok, first, you need a new altemator. When you pulled off the battery cable with the truck running . it caused a voltage spike and fried the voltage regulator, which is internal on this particular altenator. If you want to check to see if the altenator is charging, use a volt meter.

Since it wouldn't start after you put the new altenator on, it could be one of two things, either you got a bad altenator which happens sometimes or, you have a weak battery and the altenator is tryng to charge itself to death.
