Okay - this is my last plea for solutions before I have to drop the engine and replace the alternator on my 72 teener.
I've checked the tightness of the belt for possible slipping - and it's fine.
Replaced the Voltage Regulator and still get the alternator red idiot light on my panel. The battery is shot because the alternator is not charging it. I put a jump on it and it runs fine, but when I take the cables off - it will run until the engine dies (radio won't work, and only left headlight unit will come up).
Is there anything that I might be missing - or is there a sure fire way of testing the alternator to identify it as the "actual perpetrator?"
As usual - I value your 914 wisdom.
