Trip Reset Meter Repair

[flint54]

Have a 92 (electronic) speedometer. Trip odometer doesn't work. Main odometer works fine, and the trip numbers try to work, but do not. The gauge is out, and the spring-loaded reset rod (and affiliated hardware) do not appear hung up at all. I bought a spare instrument cluster at the JY, hoping to learn how to fix through some exploratory surgery, but, I'm not having much success and I don't want to ruin a good gauge. Yes, I could just live without the trip meter, but would really like to have it working. Yes, I could just send it off to some gauge shop and pay a large sum, but I was wondering if anyone has any success (and advice) at repairing this newer style? If it turns out that I have to just replace my gauge with the spare gauge, where/how are these controlled for various gear ratios? (since came out of an auto XJ, probably different ratio than my MJ) Thanks!

I've repaired plenty of the cable driven speedos, but also have had no luck with the 91 and above "tamper proof" electronic speedos. You've got a stripped gear in the trip meter assembly most likely. Easiest repair is to just swap in a new speedo. The 91 and up speedos are all the same and are driven by pulses from the VSS determined by the speedo gear. It will be calibrated the same as your broken one, but of course your mileage will be different.
