Hello all…my 2000 Gem with the upgraded motor stopped working. All I get is a click when I push the accelerator. I think I may need a controller. Do any of you have a used T1 that might be for sale? Or…any tips to determine if my controller is really toasted? ---

The controller is what activates the click so not completely dead. I you know someone with sentry sw, they can test all the ins and outs easily. Like F-R switch etc. ---

Can you elaborate on what or who Sentry sw is please? Thank you. ---

Sentry is the name of the GE programming sw. With it you can monitor the controller functions, switch positions, voltages, throttle position, etc. on computer. ---

Ok…yes, understood now. I think a fellow here in San Diego had one and would rent it out, Marlon was/is his name. But I do not think he is in business any longer… ---

If you are computer savvy, I can rent one. Or you can buy sw and usb dongle for $150. This one has monitor function, and the programming port stays with the car, for future use. ---

Thank you. Are you saying I can program from my laptop with the sw and usb dongle? My son-in-law is a software engineer, so that part could be handled. What is the source to purchase these? My cart is giving a code 65 and when the foot pedal is pressed down it changes to an 06 code.
