Some of the following codes do not appear in the factory manual. Not all of these codes will necessarily apply to all model years. Corrective actions are listed following each code. Thanks to several other members and Ride for Fun who have provided new codes for this list. Also see my post listing the Zivan NG1 charger errors. http://www.electricforum.com/cars/neighborhood-electric-vehicles-hev/2507-zivan-ng1-charger-error-codes.html

I found an error code that only comes up when you try to reprogram the controllerā¦ #14
after several tries to make changes and kept getting this numberā¦ I have decided that it is sayingā¦ āI am smarter than you and I will not give you back your toy until you put the changes back to stock settingsā
Researched and found origin of -14 error code. āRolling radius or gear ratio are out of limits for motor.ā Suggest that you have the controller inspected and reprogrammed by Marlon, Ride for Fun, or another reputable shop.
All GE motor controller error codes that I am aware of contain two digits. It is possible that the program has become āfrozenā and needs to be restarted. Unplug the charger and turn off the master switch for ten seconds or so. The switch is in different locations depending on year. Early ones were under the front seat, while later ones are on the dash. What year do you have?
[QUOTE=fatdog;12216]Thanks for the quick response!!! One more question: Is the 2001 GEM supposed to have a solenoid to operate the contactor?[/QUOTE]
Generally, a solenoid is an enclosed single pole cylindrical switch while a contactor is often multi-pole and has contacts that are visible. Both are also known as relays. A small current is used to control a large current. Most electric traction equipment has such a device to have a positive way to cut off power to the motor in the event of runaway. This contactor is what makes the audible click as the GEM is powered up.
so what is the issue if mine doesnāt make the noiseā¦ I have had the controller rebuilt after new batteries tooā¦ FSIP did the rebuildā¦ then I still had the -43 errorā¦ so I sent it back and had it rebuilt againā¦ they said they couldnāt get 1st one to failā¦ so they sent me another one, ā¦ installed it today, and now have a -16ā¦ I also have a constant BEEP-BUZZ when in road modeā¦ nothing in turfā¦
Here are some possible reasons the main contactor will not close:
the parking brake is on
the parking brake interlock switch is stuck
the charger is plugged in
the charger interlock switch is stuck
the throttle switch is stuck open
the main contactor coil is shorted or open
the key switch is shorted or open
the wire harness connector on the steering column has overheated
For the -43 code:
Check all four connections to the motor. Rust will collect between the terminals and short out. Check continuity through each pair of motor leads and from each lead to ground. One lead will need to come off to check continuity. Do not force rusted motor leads as the brush stud and insulator will break. These are not replaceable. Remove any rusted motor lead from the other end at the controller. Also check for any loose connections at the controller.
I have a problem with my 2008 gem that i have not seen on the forum yet. My gem is driving perfectly except it will not drive in the high speed. Turf mode and reverse are fine and get about 25 miles on full charge. Individual battery volts range from 12.47 to 12.63 volts. It is throwing no codes at rest. While driving in low speed turf mode, if I switch to high speed it will register 06 but nothing while at rest. When not moving, if i put it in high speed, the rectangle blinks around all of the gear indicators. No response and no code. The only thing that has happenned to the car is the charge went below the limit of the Delta Q charger. I charged the batteries individually until the on board charger would charge them the rest of the way. This is a 2008 e2 with 300 miles. yes I said three hundred. Batteries are two and 1/2 years old.
A voltage range from 12.47 to 12.63 volts is too wide. One or more of your batteries may be weak. This would not prevent the GEM from working in the road setting. Check the continuity from the controller to the road switch and back to the controller. The connector where the steering column harness attaches to the main harness is a weak point. More than one of ours has been bridged. We have never had a controller that would not work in road and turf
More than likely, the 12.47 is bad. Just to be sure, try charging this battery on a 12 volt charger. If it wonāt show 12.6 an hour after finishing the charge, it is weak. If the batteries are flooded, check with a hydrometer. Look for differences between batteries. Batteries that wonāt come up to full voltage will often cause charger time out errors and get warm with the familiar rotten egg smell.
I have been running strong since last yearā¦ Even played some winter golf through the snow driftsā¦ Backed out of garage last night fine. Put in fwd n nothing? Error 23ā¦ Says inspect controller. Does that mean ship it off to FSIP who rebuilt it ? Thx
Hi: I am the owner of a 2008 Gem Cart and I have the error codes 81 and 82. Is that something that can be fixed by an amateur?? I just had new batteries put in after trying out AGM batteries that wouldnāt work. I finally got Trojans and a watering system. I didnāt like the original gel batteries as I never did get full performance on them.
