Just went to look at a very clean 940 turbo wagon. About 120K miles on the clock. However:

1. The current owner does not have extensive service records, which means that I'd do a timing belt change as a matter of course. That's something I could handle on my own.

2. Looks like some oil leakage at the turbo hoses, which could mean a turbo rebuild and turbo hose replacement ($$$$, per the FAQ).

So far, normal wear and tear. But the BIG issues are electrical:

3. Owner has been experiencing stalling on start up, and has been taking it to a (non-Volvo) repair shop, who has been selectively throwing parts at the problem. New alternator and battery installed in February. Owner said that she last drove the car a week ago, but the battery was virtually dead when I tried to start it up tonight. I had to jump the car to start it. Yellow warning light on the dash when I turn the headlights on, which the owner said occasionally goes into flashing mode. Power windows, mirrors and sunroof all work fine.

All of my instincts are telling to to run, and yet . . . .

How tough is it to diagnose electrical issues on these cars? I've had some experience with a multi-meter (though not a lot).

Thanks a lot for any help.
