Alpine v12 help

[Crazzydan]

Well i picked up a Alpine v12 MRV-t657 2/1

IM having internal problems with the amp i got it for free so if i mess it up worse i dnt care but anyways. The amp when i plug the power remote and ground in throws the amp into protection mode

But straight to the point i took the amp aprt and looked at theres nothing fried no transistors fried no caps blown i eveen gently cleaned the amp with rubbing alchohol and electronic cleaner but i beleive its a ground problem internally but i cnt figure it out where should i look. the power light blinks and the protection is on but the music light is fine. I have put the multi-meter on it measures the ohm load and the DC load

(There are no speakers hooked up to it just the basic 3 needed to turn on)

Please dnt post common remedys i have looked through the amp pretty good, i also have had someone who has worked on computers and arcade machine electronics look at it and he thinks its a ground.
