Have 1996 P38. Recently if the car is sitting for 3 or more days the battery drains. I can't find anything on. However, the seat belt mechanism has failed at the same time -- belt won't retract and I get a constant SRS and AIRBAG FAULT warning light.

Can the seat belt mechanism failure induce anything to stay on and drain the battery over time?

Any suggestions? I've run an OBD-II scan, nothing comes up.

HELP!

 

battery drain starts with an Ammeter reading. if should be less then 50 milliamps with everything off. if not you got a drain. Then start pulling fuses till you find the culprit circuit and start by checking for damage to those circuits.
