Hi... We are new to the golf carts. Got the cart recently and have a problem of melting coil no 3. We replaced the coil only to have the new one melt. Bought new batteries, replaced all 6 gauge cables with 4 gauge and replaced the coil. After reading some of the forum postings.... cleaned the speed control contacts (3 & 4 had corrosion connecting them). I ran some voltage readings.... 37.5 volts across batteries. With key on, forward position.... had power on the right side and the two small wire connectors on the solenoid (with pedal pushed down) but no power on the output side of the solenoid. Figured that the solenoid was faulty (no click) and purchased a new one. The new one is giving the same results as the old one. We had tried to jump the old solenoid with a 4 gauge cable.... ( as suggested in another posting) but got such a spark that we pulled it away, thinking that we might fry something if we continued. Any suggestions would be greatly appreciated.
