On older 700 series volvos a lot of fuel gauge not working/instrumentation problems/starting/charging problems are caused by the printed circuit board soldering starting to break up due to the location being next to windscreen demisters.
These are notorious for failure.
Tey can sometimes be successfully resoldered on the back where the wire links connect but are quite fragile.
I have just yesterday recieved a replacement -pcb volvo call this a lighting plate- for my 1990 760 gle turbo diesel estate car.
Could not get one throughvolvo so located a volvo classic car dealer agent who tracked me one down in gothenberg.
I had a new volvo 360 that just died intermittently on me, left it for 5 minutes, started up and would not happen again for 6-7 days, then same thing again. Went back to the dealer for a week this also turned out to be the problem that time.
The new pcb board on my 760 is manufactured in japan.
Volvo tend to say these pcb boards are not a problem, but through the uk volvo club have concluded they are a major source of speedo/fuel gauge/engine temp/abs light failure problems.
