Title: eletric fan
Post by: stevens on December 03, 2007, 05:44:08 pm

I installed a flexlight fan on my 78 p/u 350 and need some kind of diagram for wiring it, I hook up both red wires to the battery, put the thermstat in, and grounded it, got it warmed up and it does nothing. On the thermstat box it has  m+,m-, +, G, m, cb for the wires. ?????  :-\

a 100a is a safe and easily obtained replacement..almost any parts store stocks reman 100a alts fairly cheap. If you have plans to load it up with other electronic devices, bigger is better if you can afford it..
