Cart shuts down randomly
Have a 93 club car DS. I did solid-state conversion probably four years ago and did all new cables, controller, Accelerator (pb6?) Motor and all from Scotty B. Everything has gone well and you can see my build in older posts. Now, Cart randomly shuts off and still shows 50 V on the digital meter. Went through all the cables recently and cleaned all battery cables and terminals replaced a few cable lugs and checked all the wiring for anything obvious. I Can hear solenoid click on accelerator and can see green light on controller. Weird part is, Green light will come on at the beginning of accelerator stroke and then go off about a quarter way through and then back on towards full throttle. No movement in forward or reverse. What should I be looking for? It's all at once, not shuttering or back-and-forth. No Change turning key off and on. Also checked pb6 with ohm meter and shows like 5.64 at full throttle? Haven't hooked up when it's not wanting to move, but that was my first thought was pb6 going out. Any help appreciated!

What's vdc? And are you saying that I should depress the pedal just slightly and check voltage as I am pushing throttle? I understand the big posts on the solenoid but didn't realize the controller did anything for the solenoid. Sent from my iPhone using Tapatalk |

Re: Cart shuts down randomly
OK, so new update. I replaced my PB6 with a new one from ebay, per suggestion of Scottyb. Well, it ran fine THAT day. Next day, wouldn't move. day after, moved fine in the barn but i wouldn't leave the house site for fear of getting stuck agaain. SO what should i be looking for next? Im thinking solenoid? or the resistors that i installed with it? Thought someone mentioned that. Can I replace solenoid and resistors just in case? HELP!!!!! Volt meter still shows 50+ meters whether moving or not.......

Jack up one rear wheel, clip the DVM leads to the large terminals, should have 48 volts. Press the accelerator and see if the voltage drops to 0. If not, the contacts are burned. |

Re: Cart shuts down randomly
I’ll do this tonight. Can you tell me, how does this relate to it working intermittently

You could install a voltmeter TEMPORARILY across the large posts. It should read 48 volts nominal and then go to 0 volts when it closes. This way you could actually check it while you drive it around the yard. If you read anything but 0 volts when it closes, the contacts are corrupted. The solenoid will need to be replaced. Make sure there is a diode installed correctly on the solenoid coil. This will prevent back EMF voltages from arcing the contacts when they open. The banded side must be on the POSITIVE coil terminal, normally the solid blue wire. If the solenoid does not have a diode or it is open, there is your cause for the solenoid failure.
