Trying to sort out the new everything. Engine runs well, but, when it comes time to turn it off it won't stop if I have my foot on the brake, although it does start running a little rough and weak. I must have a backfeed somewhere that I haven't been able to find. There weren't any modifications to the brake circuit wiring. I have a new engine harness that came with the conversion to HEI and an internally regulated alternator already wired in. I have noticed that if I put the brake on when the key is off that the alternator light comes on. ANY ideas on how to track this down?

ummmm, i think u have major issues in your wiring. the brake wiring should nowhere touch the ignition wiring. but ne ways, so if you let off the brake with the key off does it shut off? if so, check and trace the wire on the brake light switch that is mouned on the pedal. also, check voltage and trace the SINGLE (you should only have a single wire powering the coil) power wire to the coil and see if it has ne splices/ anything UNUSUAL going off of it. but i think the key is the brake pedal switch on the pedal if u say it lights up ur alternator light. i dunno, even trace the alternator wires two (should be 3)(the bolted one should go to the battery, another wire that bolts on should plug back in the alternator, and the other wire should plug in to the alternator (usually in a connector with the other wire) and run to your alternator gauge. well, i hope u understand me but good luck on your mess

Yes. if I take my foot off of the brake pedal the engine will quit. I don't have a separate coil with the HEI. I still haven't found the problem yet.

I had a similiar problem on a older corvette..When I hit the brakes all my parking lights would come on..And if i held the brakes and tried to shut it off it would diesel and eventualy stop...Problem was a bad ground...Check your grounds you could be back feeding..Through your brake lights..

Good luck

Badcaiman - You Da Man!! I disconnected the rear brake light harness in the trunk and lost the problem. I found the harness ground wire that screws into the trunk support by the trunk lock not making a ground. Took it off, cleaned it up, screwed it back on and NO MORE PROBLEM! Thanks for the reply.
