I have a Lincoln mark 8 fan in a 82 camaro the motor is a 65 327 small block. When the fan is running when I'm out driving if go to get some gas I have to jump start the car every time. Can you tell what type of alternator I need to have the fan run off of the alternator and not the battery it only happens at idle. What is the best way to wired the fan up.

This is the only fan set up I could find that would cool the motor down some.

I have 2 70 amp relays 1 for the low and the other for the high speeds. I had my old alternator rebuild to a 140 amps. When I hook it up and ran the motor then I remove 1 of the battery post the motor stop running so I no the car is running off the battery at idle. The shop that rebuild the alternator told me I have to buy some kind of RV battery now so the fan wont kill the battery. The alternator will charge at 1800 rpm or run the car with the battery post remove if I keep the motor rev high. Any help on this. What type of alternator I need.
