Where does the ground wire go on a 1965 chevy c10?

Answer 1

There is usually a bolt hole in the alternator/generator bracket. I believe it is either a 3/8" or 1/2" hole. Stock, the ground wire goes here with a bolt, lock washer, and nut.

If you have an engine that has the alternator on the opposite side of the engine from the battery, use one of the existing bolt holes in the front of the cylinder head closest to the battery. Use a bolt and lock washer to install.

In either scenario, be sure to clean off the paint where the cable end is going to touch the metal. This will ensure a good connection. I tend to use 0 gauge wire for my ground wire. A little bit of overkill, but I like to have a good ground.
