Engine/Transmission (1994 - 1998) EGT gauge gone CRAZY!!!!!!!(Autometer )

[Bug Out]

A few weeks ago while going to Tulare pulls, I noticed the EGT gauge needle would jump all over the place like I hit a hard bump. I ignored it as it only happened once or twice.



Well, this trip (11/7-10/02) it went completely haywire not long after leaving the driveway. .



It was jumping all over the place and no particular reason, bumps or otherwise. Inbetween the gauge needle hopping all over the place, I would get a EGT reading though.



I bought it from Geno's a while back. Its the "Pro-comp ultra lite 1600 degree" EGT gauge.



Any simialr problems out there? A simple fix, or is the gauge shot?



I checked the underhood connections and all seemed tight. I did not pull the guage from the A pillar mount yet.



Thanks for the help in advance.

If either of the leads are shorting to ground the meter will do crazy things.

I've got the Isspro EV gauge and when I'm going up the Lewiston Idaho grade there is one place that it goes plum nuts then it turns around and works right again, I pretty sure that it has to do with all the radio waves and mirco waves at the top that mess with mine.

I had a similar problem that progressed into a "dead needle" state where it was barely moving. Try backing off the tightness of the probe. The install instructions say not to overtighten and all the heat up/cool downs can get that nut tight enough to crush into the leads... . Might be a quick fix to try before replacement.

I had the same thing happen on a new Autometer EGT gauge. Called Autometer and they said "send it back". They sent me a new one, no more problems. I would think they would have this problem figured out by now. I have heard of it a few times since. Sorry, no easy fix I know of.

Larry, have you got the third axle under the motorhome yet?, if not look at www.usa6x6.com they have the stuff to make it happen, and it would look cool
