Hi there,
When I start the engine of my 75 camaro, I can see on my amp meter that when started, the battery keeps discharging. The alternator is spinning, and the belt is OK. Also I notice slow windshield wipers, and slow electric windows.
Only after I rev the engine up to high revs, the charging circuit suddenly kicks in. After that, the battery is being recharged, also at low revs.
I cleaned the contacts on the alternator, and the alternator is only 2 years old or so. Should it be replaced? Can it be refurbished?
thx,
Bram Stolk
