Default Alternator ground on 68

I installed new letric limited wiring harness is my 68. There is a ring terminal for alternator ground. My alternator is internally regulated, so I purchased and installed the conversion kit from lectric as well. Where should I attach the ground wire from the harness to the alternator? My alternator only has a positive terminal on the back.

If there is no screw hole on the back, ground it to anything convenient. OEM alternators have a screw hole.

Depending on the size of the ring terminal, you could use one of the long bolts that hold the alternator together.

It has to hook to the frame or engine. The wire is the ground for the front lights. The alternator was a convenient place to put it by running it with the other wires and connecting it to the spare threaded hole in the back.

You should be fine. I have a new internal regulated 100 amp alternator and there was a ground screw right on the top. I just screwed the ground terminal from my new LL harness to it and it works fine. Mines a 68 also

I'll wager that you have a threaded hole on your alternator for the ground, you're just not seeing it. On my Powermaster alt. it is at six o'clock as shown in the picture below. I used a stud since a bolt was hard to get in that tight spot. And it was metric thread, M8 x 1.25.
