Re: Wiring diagram older Marathon
I thank you for your response and help.I already replaced my F/R switch with a new one and it started to do the same thing.I never had this problem until I reinstalled the motor.My motor has 4 studs all in a row,they are not stagged like the one's in the diagram you sent me so I'am really confused on what stud is what?If you want to read a long story on how this all came about my first post was on April 20,2013.Now I wish I never messed with anything but common sense told me I shouldn't keep driving the cart with locking vise grips to hold the one wire to the broken stud on the motor.Looking down at the motor area from the front of the cart my motor has 1 stud on the left,then 3" to the right the next 3 studs are all in the same row just 2" apart from each other.The 3rd stud from the left,2nd from the right is the one that was my original problem.It was loose in the body of the motor,I couldn't tighten it up from the outside,I was just going to add another nut then attach the wire back and top it off with another nut on top but the threads were screwed up,I couldn't tighten anything up-worried I snap the whole stud off I just rigged it up with locking pliers and a hose clamp.The wire went to the F/R switch of course,looking down from the front of the cart and using a clock as a reference with the bottom being 12 o'clock the top 6,this wire went to the 9 o'clock position,left middle on the F/R switch.I know just enough to be dangerous,I'am 99% sure I wired everthing back the way I took it off before I had the motor worked on.The guy that did it owns a electic/motor rebuilding company,he did it for free cause he friends with my brother,I know he's not a golf cart expert but he forgot more then I will ever know about motors/electricty,so before I get back with him and maybe insult him and loose a friendship I figured I better be 100% sure this isn't cause by me doing something wrong.This is sparking/getting so hot it's starting to melt 2 of the pads and 2 of the contacts on the F/R board.Common sense tell's me I have a direct short now but why?If I kept it in forward I was able to drive the cart just fine so I guessed my F/R switch must be screwed up so I ordered parts to rebuild it-4 new pads and a new contact board the pads rotate on.Put it all back together, forward worked great,as soon as I switched it to reverse,major sparks flying all over,switched back to forward position to stop sparking,inspected F/R switch and it's starting to burn up exactly like my original-2 pads & 2 contacts on the new setup>WHAT DO YOU THINK??Sorry this is so long but I figured the more you knew the easier it might be for you to help me.Please help me if you can.
