Very helpful thread - I hope this clears up my intermittent stalls!

For those with the 89 8797 000 relay, the question came up about polarity on the 100uF 16V cap. Mine has a black "-" on the top, next to the 100uF marking, that is on the negative side. I verified that the 100uF and 22uF caps are ...

OK, I'm pretty sure I found the problem, so I'm updating this old thread.

It finally died for more than a few minutes (and close to home), giving me time to get to where my son was with a meter.

I found no voltage at all at the main fuse box, and a 12v drop between the fuse box input and the ...

Cash is a bit short after some other expensive car work, so I repaired the cracked expansion tank with multiple layers of JB Weld, after lightly sanding the area around it and cleaning it with alcohol. The first layer cracked and developed a much smaller leak, so I put a few more on, which have ...

Are the troublesome CDs factory pressed or burned discs?

Lots of older CD players have trouble with burned discs, and the easiest way to avoid it is a modern head unit. Many times, burning the disk at half of maximum speed makes them more readable, but this didn't work on my SC-901 in my 99 C70, so ...

Dunno about the SC-815, but my 99 SC-901 won't read burned CDs any more, and hasn't for years. That can be a risk with older head units. My wife's 6CD changer in her 97 850GLT reads them fine, though the base unit sound isn't great.

I'd second the suggestion for putting a modern head unit in, as ...

I've got a 99 C70 LPT hard top (I needed the trunk space!), and it's been a great car, with a few typical Volvo problems. Here's what's been a bother on mine:

- Electrical switches for the windows have failed several times.
- 3 out of 5 of the ignition coils have failed within the last year or two ...

My 99 C70 does this too. It's a high-pitched whine that builds and drifts away when the AC is running. It usually makes its last gasp a short time after the engine's shut off. It's definitely annoying and potentially embarassing!

The mechanic said it was the expansion valve. At the time, I was ...

I'm looking at a smaller replacement for my aging 97 850GLT wagon, and was looking at the V50, but they're in short supply. There are some pretty good deals on the S40 R series at a lot near me.

Are these decent? Are they holding up well? Any feedback would be good.

I don't know much about them ...

Thanks - I didn't see that. It's a little non-intuitive, but I'm sure i'll figure it out.

I've got an ongoing intermittent electrical power loss on my 99 C70, where it dies stone cold dead - no dash lights, no power to anything at all. This usually happens at low speeds when braking, and is sometimes preceded by the stereo power dropping in and out.

After just a minute, it starts up ...
