I do not know how it went into protect.
I responded to an ad for $100 for it on craigslist.
Met with the guy and hooked it up, it went into protect when I put the remote on it.
Guy said it used to work fine last he knew.
So he took 30 for it.
Thats all I know he had it on an l7 15. d4 i assume.
No burns anywhere even took the fet clamps off and flipped the board over no burns
