I know how to find an "open" and a "positive to ground" short and how to trace the wires. HOWEVER, I DO NOT KNOW how to find a "positive to positive" short much less trace it and can't find anything on the internet. Any help would be greatly appreciated because I'm not looking forward to tearing the dash apart to get at the "brain box" bolts and main fuse box bolts. The problem is probably under one of those thanks to rodents but I can't be sure. Thanks, Max
