Hello All,

I want to share with all who helped me with their advice and comments what was the cause of the problem I described above. The Anti-Theft Alarm Relay, Part # 9128903 was failing. It looks like a big relay fuse or module and it has a double plug. It is large, about 2 1/2 long and 1 inch wide, with a red color plastic cap. I think it plugs under the dashboard. My garage which specializes, diagnosed the problem. Volvo doesn't sell this relay anymore, but fortunately the garage had some used relays they saved off old parts cars. I was very lucky they had one.

I am relieved. I thought the problem may have been due to short in the wiring harness due to age or possibly a short in the ignition system. I've had the car back for a few days and no problems. I want you to all know, when I dropped off the car, I printed all your suggestions and provided them to the garage. You collective advice may well have lead to the diagnosis. "You've done good!"

Hugh
