I have a 66 coupe and need some advice on a power source for my electric fan. I am currently using the solenoid but the problem is when stopping for a few minutes (gas station) and trying to hot start the fan kicks on and quickly drains the battery. In turn the car will not start..big PITA and embarrassing to need a jump. I know I could wire a switch inline but I'm afraid I'd forget to turn it on and overheat. I'd prefer to power the fan with another lead that is only hot when the car is running but do not know where that could be (stock wiring). Any help is appreciated!
