Hello everyone. Need some help/suggestions. It apears my pyrometer guage has stopped working. I've noticed that it doesn't read the same temps it did before. This past weekend I towed my toyhauler, going about 70-75 and it read 300-400. This doesn't seem normal. The needle still moves but it just doesn't read right. Any ideas anyone. The gauges are probably less than a year old. Thanks everyone.
