Well, ive had my gauge in for a while now, both a Boost and EGT 60mm Electric Greddy Peak Hold and Warnings. Anyways, this morning on the way to work (the first morning it has rained with them) that my greddy EGT gauge seemeed to be jumping around, it would jump each time my windshield wipers would move and then i turned on my turn signal and would pulse with each click of the turn signal. I also noticed it would jump around when i go over a pretty good bump in the road. Any thoughts on why it would start jumping around this morning while raining, or what may be causing it to jump around? I plan to check the back of the gauge sometime soon to make sure the harness is plugged into it.
