Thank you for a very informative answer.

I've experienced clock-capacitor problem. It never stopped but ran slower with cold weather. Finally figured it was cold related and put clock in freezer with 12 volt supply. I'm not an electronic tech but knew enough about electrolitic capacitors to be suspicious. Bought replacements at Radio Shack for $3 and clock worked fine in freezer and so far the clock's worked another 5 years. Mentioned rerplacing clock capacitors once to a Volvo machanic who spent $250(?) his cost for a new clock from Volvo and watched his chin drop.

I have 2 spare k9800 speedo heads and didn't realize they are for station wagon until recently. Sedan uses k10000 something. Is there any way to convert 9800 to one for a sedan? Are noise capacitors the same? Wife driving sedan or I'd go pull speedo head and compare.

Just pulled spare 9800 head. It has 2 circuit boards with a pair of elecrolitics on each board. Assume problem on stepper motor side. Other circuit board must be mileage/service reminder side as it has every-5000-mile reset switch. One capacitor is larger and rated 220-6 (suspect it's supposed to be 220-16 (volt) but its clearly stamped 220-6. Large capacitor on other board is a 220-16) and the smaller one 47-16. Also read FAQ 700/900 where you have to pull needle and MPH face to access capacitors. 240 speedo circuit boards are in plain sight and both capacitors on each board can be replaced without even removing boards from the larger assembly. Still need to pull 10000 head from wifes car and make sure I'm buying correct capacitors. I'll let you know if blips gone. Still without digital camera or I'd attach pics.

Thanks again. Steve
