SL/R107: diagnosing speedo issues
Recently the speedometer has malfunctioned, will go up to about 30 mph but no higher. (The odometer didn't work when we got it, but we don't put many miles on it, so oil changes etc were done by the calendar.)
I have to try to figure out
1) Mechanically sticking needle?
2) Defective speed sensor?
3) Defective speedometer?
Andy suggestions or guidance on diagnosing?

In any case, I just went with my gut feeling and sent the speedo cluster to Southern Electronics in VA. Good service, they provided UPS both ways, did a 1 day turnaround, repaired the speedometer and odometer and did a cosmetic cleanup for 250
