I know this is an A body forum, but hopefully one of you guys can shed some light on this for me, and you've never steered me wrong yet..
We run class 8 trucks, with Detroit engines and have been having a NIGHTMARE with alternators the past couple months ...
After 3 years, one of the stock Delco alternators crapped out .. We installed a new after-market one and it was fine for a few weeks, and then it started WAY over-charging - up to 16 volts ...
Since then we have tried 3 different re-man Delco's and they are all fine for a while, charging between 13.8 and 14.2, but two had to be changed because they suddenly started dropping to 12 volts, and another was spiking at 16 volts..
We checked all the connections, re-did the chassis ground, and the batteries are less than a year old and check out fine w/ a load tester ...
We're guessing they are just crap internal voltage regulators, but don't really know ...
Anyone have any ideas ???
Thanks as always,
Kenny
