1999 GEM 48 Volt, 18MPH

GEM Forum
1

I have a 1999 GEM 48 volt that will only run 18 mph in Road and Turf mode. Maybe only 1 mph difference in the two ranges. This car has heavy duty Everstart Maxx Marine batteries. I have checked voltage on fresh charge going max speed and I show about 46 volts. Is this enough to reach the desired 21 mph. Any suggestions on how to improve speed?

I tried to download the schematic for the 1999 e580 but it says I do not have permission to go to that page.
Please help

I just downloaded it . Try another computer or connection. This schematic is for the early 48 volt GEM that used only four batteries.

Ok. I had to have at least 5 post’s before I do attachments.
Here are the photos of the board, contactors and controller.

The drawing does not show wire colors. If you have a photo of a working board I can match it up to be sure I have the colors correct
