Did you try to search old topics?

There might also be something in the pdf manuals section!

Which model Delco alternator? Single wire? It makes a difference.

Are you converting to 12 volts from 6 volts?
I have an excuse. CRS.

Here's a copy of the wiring diagram I came up with when I overhauled my electrical system. It should work for either a three wire or a one wire alternator.

It works great for me. No problems since.

Hope it helps.
