Cart Will Not Go
2002 36 Volt EZGO cart. Cart will not go and batteries are fine. I think it is a switch problem as I have had this issue before on an intermittent basis. For example, cart suddenly stops moving, then after playing with the forward/reverse switch a couple of times it goes again.
This time I backed it out of the garage, no problem, went about 20 feet and stopped, no problem, then it would not go. Playing with forward/reverse switch does no good. My question is this: assuming batteries and battery connections are good, what is most logical sequence to troubleshoot this problem and are there any known failure modes that have these symptoms that are common to this model and age cart? Thanks for your help....Bob |

Re: Cart Will Not Go
what the guys will really need to know would exactly which model you have and its drive system. if you don't know..... look at the thread below and you can easily figure out which you have.

Re: Cart Will Not Go
We do need to know which drive system but I'm guessing FNR switch on the dash ?? PDS cart. Do you get a solenoid clunk when you press the pedal ? If not, it could be the reed switch has gone bad in the charger socket. On the red wire coming out of the charge plug there should be 36+ volts between that red wire and the battery pack ground

Re: Cart Will Not Go
OK, looks like I have the Sepex with PDS (forward/reverse switch on the dash)

Re: Cart Will Not Go
I do get the solenoid clunk when the pedal is pressed and I have the 36+ volts between the red wire and ground.

Re: Cart Will Not Go
Well at this point it sounds like the activation circuit is working. I would flip the Run/Tow switch to Tow and check all the heavy wires and make sure they have a good connection. Also check the white and black smaller wires going back to the motor and especially at the pass side rear of the battery pack where it makes that turn. The wires can get worn there. If you do all that and no go. Make sure it is in Tow again.. You will need to pull off the controller cover and check the solenoid itself. It may have failed

Re: Cart Will Not Go
Putting the cart in the Tow position cuts the power to the controller.
I would jack up the rear of the cart to keep it from running over anyone first. Then to test the solenoid you will have to pull the cover and you may want to disconnect a main battery cable. Now look to see the condition of the resistor going across the main terminals. Does it looked burned ? To test the solenoid, disconnect the main lug wire that goes to the controller and remove the resistor connection from that end so nothing is on that lug. Make sure all your wires are in a safe position and not touching something they shouldn't, hook the main battery cable back up and flip the switch to Run. When you press the pedal there should be a clunk of the solenoid and 36 volts across the small terminals. There should also be 36 volts from each side of the main lugs back to the neg wire of the main battery pack. If you don't have the 36 at the small lugs, you have an activation circuit issue and the solenoid would be quiet. If you don't have it on both main lugs with the resistor removed, the solenoid is bad. |

Re: Cart Will Not Go
On the solenoid itself. One side of the solenoid will have the battery cable coming from the pack. You want to disconnect the wire going to the controller. Your trying to check to see if you get 36 volts to the controller side of the solenoid.
