Solenoid shorting out
Please bear with me. This may be kinda long. I am working on a 2001 txt. Guy called me and said it wouldn't run very long on a charge. I look at it and he had a 5 amp charger with 36 v max output. I told him he needed at least a 15 amp charger. I get him a 20 amp charger that worked fine and shut off when it needed to. Couple weeks later he calls and tells me the cart quit. I go look at it to cut some of this short the batteries were toast. 5 out of 6 shorted out. They were fine before the new charger but, were 5 years old. I bought and installed new batteries and the cart would not move, solenoid will not engage. I have changed the controller, 3 solenoids, acc. switch and. What happens is when I get all good parts and turn on the power everything is fine until I depress the accelerator, then both small solenoid connections go to a dead short and will melt the wires. I have used good parts. No telling what I have burned up now. I have to fix this short before I can do the troubleshooting procedures. HELP

Re: Solenoid shorting out
My guess is that it is a series drive and the diode was installed backwards on the solenoid coil.
Typically takes out pedal switch and/or MS-2 on F/R assembly, but may take out keyswitch or reed switch. Leave the resistor and diode off the solenoid while troubleshooting and install them after you get cart running again. |

Re: Solenoid shorting out
Diode was toast. removed and put voltage to solenoid and it clicked. Now when my acc switch comes in I can maybe make some progress. Thanks.

Re: Solenoid shorting out
Well the accel. switch came in and now the solenoid is working as it should. I have voltage on one side of the ITS. I cannot get voltage thru the ITS back to the black wire on the controller. Its new but I had that short when I put in the new one. Could it be fried? Also the only pin I get voltage in on the plug is the red one.

Re: Solenoid shorting out
I have 37 volts on 3 of the motor leads when I press the accelerator. S1 only reads 4-5 volts. Motor will run off a battery charger.
