Charging light

[Tagdot]

Ok I read a few problems her like this one but would like some Ideas,
Its a 1995 Park Ave. on it's 5th alternator in 2 years. always same thing , red light comes on and charging meter goes from 13 volts to 10 volts.
All the alternator's have been reman's. After the rebuilt alternator is installed it works fine for a short time. any ideas? should I try a brand new alternator or maybe it's a loose wire?

The previous owner of my car 91 PA went thru 4 alternators then the one i had on it when i bought it blew.. What was the fix, A NEW ALTERNATOR not a reman...the remans suck. 2 years no issues with 15V charge. forget about the remans, there horrible. Pepboys has new prostart units for 139.99.... make sure it doesn't say delco on the casing. if it doesn then its a reman.. Or just spend the $$ and go get a original from the dealer. Worth the extra spending.. make sure its a new one!!

I guess I should have tried a new one, the rebuilt one that I put in 2 days ago now isnt working right. It started out fine charging fine, then it would go from 13 volts up to 15v at the red mark then drop down to 13 then drop to 11 volts. I tested the battery voltage and it was 11.5 volts and the output at the alternator was 11.5 volts but think it was just from the battery. Is there anything else that might cause this problem before I buy a NEW alternator ? I cleaned all the connections

Turns out it was the engine control module (computer) replaced that and so far working fine. Thanks for the help
