i put the shunt back in, it was clipped, and after a few hours of looking i found the bad one, c199 over by IC4, 330uf leaked everywhere. 330uf measured 48uf on the lcr meter.... sigh, there are a couple 1uf's that were over 2uf so i replaced those also. i dont normally do cbs, but with hunting season, everyone wants me to take a gander at them lol, this poor radio must have been on a 4 wheeler, just all beat up. did what i could, but like i told the guy, if you let it ride in the floorboard, not much is going to prevent something else from happening.
