[DeTomaso] Relays, Fans, Ammeter, second thoughts and project expansion

[Charles McCall]

Your engine will stop just fine if you touch the power window button.

That's what I have to do to turn off my motor... It does that even
without the fans on, I think, so I don't think that is the cause. I
have a solution so I don't lose sleep.
