I've just took the time to clean all the connections (under the 96F SoCal Sun)
Here are my readings -
Alternator B+ > Ground = 13-16V (it moves violently) I cannot find a 30A ammeter to measure B+ > Battery +
Battery voltage -
Engine not running - 12.56
Cranking - 10.33
Idle - 13.2x
Increase engine to 1500rpm - 13.5
3000rpm with load (everything on) - 13.02-13.06
However, whenever Irelease the gas, and the engine idle again it slowly drops to12.41
Another thing - it seems the battery is not holding voltage pretty well. I've charged the battery to 12.70 volt one night, and then it becomes 12.6 again the other day, and it keeps dropping.
Time for a new Optima Red Top?
Would the 35 fit?
Or do I need a new voltage regulator too? Or even a new alternator (that's going to hurt my wallet
)
Thank you everyone.
