so back in 09 i replaced the old junk gear in my odometer with a nice new white one from Roger. fast forward to last week and she stopped working. Speedo works like a champ.

i removed the pod today (with a new green gear from roger in hand), and what should i find but the white original replacement is fine. all seems to work just fine as you turn it by hand.... the motor seems a little "notchy" if you turn the worm gear by hand.

soo...... im not sure where to go from here. how can you bench test a speedo without blowing it up? ground, power, signal.....

i can throw it all back together and hope it "works" but.... its not a hard job taking the pod out. just annoying.

Want to be

The motor can be driven directly. Though you might have a failed capacitor/resistor on the board.

well, re installed, it worked for a second... then stopped. hit reset and now it works great. ill just keep my eyes open for a unit i can get rebuilt as a spare.

now the pod rubs on the steering wheel.... LOL. never ends.

I think Dwayne had a writeup that might possibly be related. I believe it has to do with too much freeplay in the odometer number stack that would cause it to jam. The fix was adding washers and rechecking the freeplay.

i looked at that write up. no real play in mine... i think it just hates me. LOL

Most likely it's a burr on the gear you are using or a bit of debris in the motor gear after you played with it. Although we already know this because you messaged me with your success .
