I bought my current 1992 740 Non-Turbo Wagon last summer. It was maintained by a mechanic who meant well but I suspect did not know about Volvos. A few months back it began to have some weird electrical issues that I could not track down. The rear left brake/running lights failed to work but the back up and flashers on that side do work. The radio antenna failed suddenly. I think the cooling fan stopped working. All sorts of weird lights began to appear on my dash including a Service Engine light. There is a slow electrical leak that drains the battery in about two days. Well, this morning I was driving it to work and I noticed a low rumble along with felt like a few missed beats along the way. I sort of thought to myself that it might be time to clean the intake as it has been at least 5000 miles since this has been done. I thought nothing more of this and stepped into the school where I work. I came out this afternoon and the car cranks but will not fire up. I know less than squat about mechanics and particularly electrical stuff but I can follow directions if they are explicit enough. I plan on trying to get the mechanics teacher to take a look at the car next Monday as it is stranded in the parking lot. Where do I look? Are the electrical issues related to the no start? The mechanics teacher mentioned in the past that he thought my alternator might be failing thus causing the electrical problems but I found that the original owner of this car had this alternator installed in December 2006 so I was doubtful that this could fail that rapidly. Could all this be caused by a bad alternator? Relays? Any help would be deeply appreciated! Again, please explain as if talking to a non-mechanic layman as you are! Thanks!
