Weinshenker > (marcwnopsamuserve.com) Sounds like you need a good automotive electrical troubleshooter. Someone will have to isolate each leg of the door lock circuit and measure the current draw for each leg until you find the intermittant short, or high current draw. When that is found a visual inspection of the wires, connections, relays, switches, etc may yield the source of the trouble. I know I may not be much help, but that is the general idea of how to find the source of the problem. I do have a 900S and have a problem with the passive belt system draining the battery down overnight. I have been able to stop the problem by pulling the relay for the system out of the circuit, after locking the belts in the rear-lock position. Makes it a little hard to get in and out of the car but it is temporary until I get the electrical service manual to continue to troubleshoot the system. Anybody else have any ideas about passive belt electrical system? John (to reply remove z's from email)
