Nash, I figured the 100A fuse since the fan has a startup pull of about 100A.

I'm gonna try the seperate power wire this weekend. If you look at a 67 wiring diagram I used the 10 gauge wire that runs from the battery to the horn relay/alternator/voltage regulator, I just don't have the regulator any more. I thought it would be ok, but maybe not.

Lol, can't claim credit for the blue paint, came like that.
