I am building a control box for my dad for one of his tactors. He has an electric motor that runs on 12 volts and about 20 amps. I want to make a box that is as easy as possible for him to use. so I was thinking an on/off switch to control forward and reverse and a push button to power up the circuit. Here is what I have built. The system on/off is where the push button is and I have a spst switch for forward/reverse.
Problem is it keeps blowing fuses when I hit the push button. I have verified all of the connections and everything is wired as shown.
Thanks for your response. I actually just figured it out. one of the relays turned on 87 and 87a at the same time. I switched it out with a regular relay and it works perfect now!!
