Another alternator question
A customer brought his streetrod back in to show it to me after the paint was done. Nice car. Early 30's Chrysler custom car.
Anyway I did a lot of the wiring and AC on this car. I went to a lot of trouble to install a relay to operate the cooling fan. It had 10 ga wire to the fan relay from the key on power side from the main circuit board that I made (yeah I know you can buy these too) which was set up to provide "alway on power and Key on power". I also had installed a nice one way connector so the fan could be removed for radiator service if necessary and simply plugged back in. There was also a dedicated ground for the fan motor. The fan had an adjustable temp setting device built into it. Customer supplied. This all worked very well. The car could sit still in 100 deg weather with the AC on full and as many of the accessories as can be turned on at one time running and not get hot. It has a 140 amp alt. 3 wire. The fan would come on at 200 (pre set) and cool the motor back down to 180 and shut off. Even with the AC on it would cycle in 90 deg weather.
Well the body shop took all this off and now has what looks like a 12 ga wire directly from the alternator output going to the fan and the fan has another ground with an inline fuse in it, my connector is gone. The fan now runs all the time that the motor is running. While it works, my question is; is this a safe or wise thing to do??
