Just put a new set of Deka AGM BATTERIES in her and when I turn the key on Code 51 poped up on the dash. I had 12 volts in each battery. I have her plugged in now, and I hope that will help me out. And if not, any help would be appreciated. Thanks Al
Check total volts.
One battery in backwards?

I had the batteries installed by a professional. I also down loaded the battery diagram for the gem 72 volt carts the batteries are in properly. My next step is going to check the voltage at the controller. I will update soon.
You won’t have voltage at controller until relay pulls in.
Check from plus to minus. First battery to last.

Ok doing that in a couple of minutes
I have 75 volts at the batteries
The trouble tree asks to check control fuse.
Is that fuse located on or near the controller
