2001 Gem E825 electrical trouble

Hello and good day to all. I recently bought a GEM golf cart, and although I don’t know much about them, I’m learning.

Unfortunately, my cart setup didn’t come with original parts, but it did come with an old Altrax AXE 4844 controller. It has been converted to 48V.

My parts are as follows

Altrax AXE 4844 controller

Albright SW202 Reversing contactor

MZJ 48V 400A main contactor

0AWG wire

Now the issue I’m running into is upon having my Altrax Pin1 KSI wire connected I still can’t get my main solinoid to click.

Any help would be greatly appreciated
