As follow-up on the problem I was having with the speedometer/odometer in my '89 240 wagon... Replacing the 25-tooth gear fixed the odometer problem, as I expected it would... The speedometer proved to be more of a task than I really wanted. After swapping parts back and forth, I finally ended up replacing the two capacitors (220mmf and 47mmf) on the stepper-motor board, and that seems to have fixed the problem. The speedometer is now working, and I'll check the accuracy against my GPS tomorrow morning, although I don't expect it to be affected by the changed capacitors. Next time I'm at the junk yard, I may try to pickup an extra stepper-motor board, just to have on hand for the future... Again, my thanks for all the help, especially the link to the circuit diagram! parrot33 at hotmail dot com
