EGT Gauge Problem

I'm having problems again, with my EGT gauge. The needle goes CRAZY! This is the second gauge that has had problems. After the first one started having issues, I took it back to where I purchased it. They checked the sending unit, and it was good. So, they replaced the gauge. Well, 9 months later, the second gauge is having the same issue as the first. The needle goes crazy, and so am I. The place where I bought it is out of buisness.

Any suggestions?

It's a Pro-Comp Ultra-Lite Series Pyrometer

Thanks!

Could be a wiring problem somewhere

DO you have a 2 way radio in your truck? My gauge will go crazy sometimes when I transmit.

No 2-Way, but I do have Sirius Radio....would that cause a problem? It could be a wiring problem, but that was checked out too. I just hope that I don't have to by another gauge, and it goes bad also.

Sat. radio should not be a problem, I have xm and my egt gauge doesn't go erratic in it's reading. What about just the thermocoupler it self, have you checked the integrity of the probe? What about a loose connection(which I guess would go along with checking the wiring)?

Please educate me on how to check its integrity. I have no clue.

Where the probe is mounted, check to see if it still fits snug in there, I knew a guy that had his done somewhere and they hadn't tapped it just right and it was loose, free floatin round the hole and that had given him some erratic readings. You could also check the probe if there was a loose connection(where it was mounted) if there was physical damage to the probe itself. Or sometimes the coupler just goes bad, every so often that happens, if your able to get a replacement coupler and then route that and hook it up to the gauge, if it gives you solid readings then it was the coupler, if it still gives you bad readings keep the couple and try to order a gauge without the probe(I don't know if you can do that or not, I have only bought them as a set, but I do know you can get a seperate coupler by itself).
