-23 error code problems

Gem was running fine and when I went to use it -51 popped up. After checking the connections it went away and now I’m stuck with -23. Any thoughts as to what could be causing this. 2002 with sdi 22 lithium battery and t1 controller.

I saw and responded to this over on fb. Do you want it here too just for continuity?

I’d like to know… might keep me from asking a dumb question later on… Might being the key word… Lol
