I have a 1998 CC 48V cart that I was driving when it started making loud sounds of shorting and stopped running. When I got it back to the cart shed I pulled the back hatch of so I could see the wires and MC when I noticed that the white wire that went from the selonoid to the A2 terminal on the motor and the green wire that ran from the MC terminal A1 to the A1 terminal on the motor had shorted due to chaffing. I replaced the two wires and still no go. I am not getting any clicking sounds from the selonoides and noticed smoke coming from the MC . Any ideas on how I should trouble shoot this problem ? Is the MC fried or bad selonoid ? Cart S/N # A9815-656153
