Speedometer's got me stumped
Hey all, long time reader, first time OP-
I've got a broken speedometer. '93 YJ with a 2.5L and a 5-speed.
When I bought it, the speedometer didn't register at all, and the odo
was stuck at 100,722 miles. The speed sensor had the stock speedometer
gear and was wrong for the 31x10.5 tires that came with the Jeep, so I
replaced the gear with a 38 tooth and made sure to index it properly. I
was really hoping that the indexing was the problem, but alas no.
Is there any other common cause of speedometer failure in these YJs?
I've been reading a lot online, but the only troubles I've read about
come from improper indexing. Is the gauge itself prone to failure from
shorts or loose wires? Any other suggestions, tips, hints, or tricks?
I'd even take a few good curses and threats, if they'd do any good.
Just in case they may be related, the only other problems with the Jeep
are that the temperature gauge is being temperamental (groan!) and is
acting like it has a loose wire somewhere, and the oil gauge isn't
reading at all (probably a bad sender).
I've got this bad feeling that I'm going to be digging into the dash
this coming weekend...

Re: Speedometer's got me stumped
Hi Garth,
Your speedometer is motor driven so it could be related to your
temperature and oil pressure gauges. I'm betting someone got in there
trying to turn back the odometer, and probably broke the gear cogs, then
threw back together, probably forgetting something as simple as
grounding the panel. I think I'd start off with panel out of a bone
yard, just because the mileage it stopped at. Buy a vote meter.

Is that what they call that device used to measure chads in Florida?

The proper term is "multimeter" unless you explicitly only wanted one that
could measure "volts", in which case it would have been called a
"voltmeter"...
