Is the B- wired correctly?
Do you have a picture of your wiring maybe?

I’ve literally been scratching my head ripping batteries down to check wiring, testing others swapping to another LLT everything. because I wired it like this, like a d140 oof (b- is linked internally) ah humility come at me.

I’d have a guess of a low voltage supply under powering a proseser. How well do you work with no energy.
