2002 EZGO Western 42 V quit after slow speed jerking on takeoff
Looking for help. Several days ago cart started hesitating at slow speed takeoff. Seemed to run ok after initial hesitation. Yesterday it jerked badly at initial acceleration, and started slowing down eventually stopping and stranding me. The Curtis battery indicator was showing full battery charge but got dimmer and dimmer(not lower) and finally faded out. Will not light now with any bars.
I have 6month old T105's that are at 46-47 volts, so essentially full charge. Solenoid test: solenoid does NOT click. Solenoid battery side main terminal is full pack voltage46v, the other main shows 36 v. No voltage on either small terminal. Controller voltage at B+ is 36V with ignition switch off or on. 1, 2, or 3 terminals show no voltage. With Ignition switch off, voltage at FNR switches is 27v. With switch on is 1v. I have checked connections, fuses that I can find. So what have I got here? A bad Controller? Thanks for any help and advice!! Randy |

It’s a series cart, correct?

The whole thing about the energy meter is good hint. The meter is not powered by the motor controller. You are losing power somewhere else I think.

Re: 2002 EZGO Western 42 V quit after slow speed jerking on takeoff
There’s a wiring diagram for series carts in the stickies. If the solenoid isn’t clicking, the problem is in that circuit, the little wires, not the cables or controller. It’s starts at the reed switch, goes to the micro 2 on the f/r, through the key switch, then to the micro in the pedal box.
I found a pic, it’s the non highlighted wires. |
