To funny, I rewired the fuel pump when I switched to positive ground. I was joking about the motor running backwards someone made a comment about it in an earlier post.
So everything should work with a negative ground but it would not be optimal. I plan to switch it back to positive ground, verify the coil and generator are wired correctly so the battery will not have reverse polarity feeding back into it. I plan to go back to the mechanical fuel pump. Is there anything else I need to do that you can think of?
