I bought a new bosch alternator from Bursons which is meant to be the compatiable direct replcement for the v8 hatch.
No biggy. Shelled out the couple odd hundred bucks and wack it on...gilmer drive of course too
Didn't see it at first but its got 2 blade terminals at the back plus the battery charge terminal. Right, wacked the signal wire lead on the right termal eventually and sweet ..its charging. here now lies the problem.
I upgraded the ignition system. New recurved electronic holden distributor and relay to get direct 12 volts from the battery to coil and distributor. Using the old ignition coil wire to trigger the relay.. easy..yeah..
Heres the problem. With the relay in the system, ive just detected that 4 volts is being shoved up the signal wire and back feeding into the electrical system so when I turn the key off ...it keeps running and it wont shut off. just enough volts to keep the relay active.
Any idea's ? .. swear I'm gonna put a match to the thing soon ..FFS
This was all done chasing weak spark and shitty firing..
