quick run down; got an '86 Z28 with 5.0 TPI, bought it 4 months ago.

the wiring in the battery was a mess, so i decided to give it a go-over...

replaced a lot of dodgy connections, and damaged wires, plus removed a wire going from the alternator to the battery (not the main charge cable... someone had added a cable from the connector on the top of the alternator, going to the battery..

ok, story now is, the thing refuses to charge, i have tried rewiring the connections back as they were, but it makes no difference at all in the charge voltage (the engine idle RPM goes a bit up as i connect the mysterious wire, then drops back down after 10 secs.)

one thing i have been thinking about... i had to move the car, and forgot to connect the main cable going to the alternator, and some other accessories.. is there a chance that cranking the engine without that wire connected may have bured my alternator? the alternator appears to be pretty new, so i do not believe it is worn out...

any clues is greatly appreciated

(and ignore the spelling mistakes please... i'm Norwegian, and not too good at technical english)

Take the alternator out of the car and to a parts store so they can test it. Sounds like you may have burned a diode out.
Just a warning...if you end up buying a rebuilt alternator, make them test it before you walk out the store with it. I made that mistake just a week ago and had to go right back again the next day.
