hi all looking at a 1266x for a member, 12v going in 12v being taken lower voltages being converted, all chips working boards like new, but it wont run.
from what i understand the main thing that kills these is reversed battery polarity,checked this and ok any other things go wrong with these.
what should the bottom boardclamp looklike? and should the two traces one on top board and one on bottom board be connected.
what i mean is the two small traces that go to the separator standoffs that separate the boards, the traces one on each board go nowhere except to the standoffs, but the two stand offs are isolated.
cant see them on the schematic, it sees like they are earths to me and that something is missing, i dont think the two boards are assembled correctly.
i will dig out the camera a take some pics.
