I have a 2002 Gem Car that is a 48 volt. I am looking for a good used Controller? I have the batteries in and still no power can anyone suggest anything that might be wrong? ---

Hmmm They didn’t build a 48 volt GEM in 2002. I believe the last year of the 48 volt was 1997 or early 1998. Your model number says it’s a 72 volt What is the model # of the existing controller? What is all the information on the tag on the motor? Rodney ---

I can’t argue with you but it does say 48volt and I have a couple of things that tell me it is a 48 volt. Also I have talked to you before when I first started trying to fix this and you told me it was a 48 volt by the looks of everyting. ---

How many batteries? Assuming 12v each, 4 is 48v and 6 is 72v. ---

Yes I did. How ever I didn’t know the vin at the time. So - lets start over. 1 You said it ran when you bought it. 2 You said it had 4 batteries. Were they 12 volt? 3 Is the Dc/Dc converter a SurePower in an Aluminum case or a n open circuit board? Look at motor. what is the information on the tag? Are the motor wire terminals marked A and F or A and S. ---

You might look at the Altrax controllers. Not that expensive new and you can get one that takes 48 to 72 volts and is programmable. ---
