Thanks to all you guys help, my 93 F250 7.3 runs great, but... I have a battery drain that kills the batteries overnight. Batteries test good, alternator also test good, (new Alt), New Battery Positive cable. I have tracked the drain to 13, that powers the RABS system, brake lights, flashers. If I remove that fuse, batteries do not drain. Even after 5 days. I have unhooked the brake light switch, still drawing, disconnected the harness for the rear lights, still draws, Could the rabs module behind the glovebox drain the batteries, as it has power at all times? Where else should I check? A new module is not real expensive, but I hate to change out workink parts.
Thanks,
Dale
