I have an older style square trim gauge that’s having issues. It will say -4 when it’s all the way down for a bit like it’s supposed to but then just start showing random numbers. I changed out the potentiometer to a new one but it didn’t change anything. I had an issue a few years ago where the gauge wouldn’t change at all (stuck at 65 or something) so I got a replacement and it worked up until recently. Is the gauge bad again? Is there a way to troubleshoot? Those gauges are hard to come by and expensive so I don’t want to get one without being fairly certain it will fix the problem. Thanks for any help.
