I installed a new Taurus fan on my 70 Camaro 2 speed fan with two temperature switches, Big relays the whole nine yards. Everything works great started the car let it come up to temp low side kicks on cools car down and shuts back off. well I turned the car off while the fan was running....the fans slows to a stop and then try to start the car again and it just clicks after about one rotation of the engine. If the fan is calling for power is my battery not strong enough to turn the engine over while the fan is calling for power? I check the voltage on my battery and it was reading 10 and a half to 11 volts so it's not weak. My alternator is a 81 amps I think.... Could the small Amp output cause this issue?
