charge light / alt problem


Recommended Posts

Since those things are ok then you need to check the voltage to the field of the alternator (the small wire). You should have nearly the same voltage as the battery level.

 

It could be your new alternator has prematurely failed also. If your field voltage is ok then you are going to need another alternator. Was this one a new unit?

Two things that I have found cause pre-mature alternator failures until they are resolved:

 

A bad battery, terminals or cabling. An open circuit(intermittant or not) will almost always kill an alternator when the engine is running.

 

Excessive oil in the engine compartment to the point of coating the alternator will also cause the alternator to fail.
