Anybody know where I can find a wire harness for a 67 C-code alternator. I've discovered that the ground wire from the engine block to the back of the alternator is non-existant. I'm assuming there should be one. My lights have been flickering, more like pulsating, for quite some time (many years actually). I'm wondering if getting the altermator grounded would help.

Is it all of your lights or just your headlights? It should have a ground wire attached, but in all reality it should be grounding through the case.

If it's just you headlights flickering, it sounds more like the headlight switch. Or if its all of the lights, it sounds like the alt just isn't putting out the amps that it should be.

on my '68 coupe in-line six the alt gnd is about a #12 blk with red stripe going from gnd term on alt to lower engine block - another smaller red with black stripe is also tied with it at the block with spade lug that i recall goes over to volt reg.

Your alternator should be grounded with a dedicated wire. You can run a wire from the "GND" terminal behind the alternator to the engine block (where the battery negative cable is connected) and on to one of the sheet metal mounting screws on the regulator. If the pulsating continues might try a new regulator.

Thanks for all your replys. As part of detailing the engine compartment over the last month, I spent the $20 to get a new alternator. Made no difference. I'll try the dedicated ground between the alternator, block and ragulator. The regulator was last changed about 18 years ago. Perhaps it's tired.
