Hi,

If the alternator is over then under charging the most likely cause is the internal voltage regulator.If the Alt. was bench tested properly this should have been isolated.If the belt were loose you would have primarily an undercharging condition,not both.The only other thing to check is the connections at the battery and the alternator to make sure they are clean,dry,tight and free from corrosion.


Thank You

I have an '02 Buick Rendezvous with a problem with the charging system. I got a new battery but haven't changed the alt. Some people have told me its the alt wire that charges the batt. Please help.


Yes that is true BUT
most of the time this is simply a dirty cable to battery connection.
Did you clean the cable connection down to silver color inside when you changed the batt? Folks buy new batts all the time when all they needed to do was clean and tighten them.
With the engine running put volt meter test leads one to ground and on each side of of alt out wires one then the other. should be 13+ volts
then put them on each side of battery and it should be the same. If not take it to the Auto PARTS store and have them check the alt for free.

Hope this helps Mike

Check for a charge fuse,and check the large wire on the back of the alternator to make sure it is going to the battery,the voltage from the alternator to the battery.
