Brand New Grizzly Won’t Start

Just brought the quad home from the dealer. I rode a few km with no issue. When I went to install my heated grips, something happened. They are Moose Dual zone, same as heat demons.

I turned the key, the grips worked, but I have no display and it won’t start. I can still use my winch, so it seems accessories work.

All fuses are Metered good.
Battery is at 12.6V. Even tried boosting it with a plug in battery booster.

I used the ground on the battery, and I found a red wire that had an open splice end. Looks like it was connected to the ignition or the 12v plug. Even with the current issue, there is still 12V going to that wire when the key is turned on.

Any suggestions.

I am an Avionics guy, so I know my way around wires/electronics, so throw the jargon at me. I am new to the Grizzly so I must be missing something. A relay possibly?

Thanks for the help.
