Wondering if anyone has seen this before - I have a Autometer pyrometer in my 40 that for seemingly no reason suddenly jumped to around 1400 degrees and just stays there. When I turn the key on, it resets to zero and then jumps back to the same position, and doesn't seem to move from there at all, even when driving. Would that be a probe problem? I thought maybe the wire to the probe might have shorted on something, but its a steel braided covering, and I doubt it would wear through. I haven't gone through it carefully yet, just kinda looked at it and saw that it wasn't touching anything and thought I would check here first before I started ripping out wires. Any clues? Thanks!
Routed it too close to hot stuff. I nipped off about six inches of the steel braiding, and separated the two wires inside and taped everything back up. As soon as I did that the pyrometer jumped down to zero, so I put everything back together, rotated the probe so that the wire coming out was pointing towards my fender and re-routed the wire far away from any heat source. So its all good. Thanks for your suggestions guys.
