Unit Issue or Just a Bad Day????

[svt2205]

Our weather has been super nice lately. I noticed this odd occurance when the temp was about 60 give or take a few degrees. I'll check battery voltage, but I'm not expecting any issues there. I bought a large capacity battery back in November and just replaced my serpentine belt. The old battery wasn't too great add the plow and I had an unreliable system.

Yes, the built in tach on my Gryphon read 0. Surprised me. I shut the truck off. Opened the door, to kill the delayed power and started it back up. It worked fine, except for the display going to 0 when I was adjusting brightness.

My luck with things hasn't been great lately, so maybe it's just a bad day. Today I didn't notice anything funky, but I also didn't make any sort of adjustments.

Thanks for your ideas.

By the way it was 88 today. Too warm for my early spring blood.
