Is anyone having problem with your pryo? I'm on my second in three months and it's stuck on 750 right now. Same thing happened on the first gauge except it stuck on 450. They seem to work about a month then stick. What could be the problem?

 

It is the power source you are hooking them up to. It has to be a clean on/off power source. I have been using a relay to do the on/off power for those gauges.

 

No problem with mine in 2+ years. I'm also running mine through a relay and fuse protected power source (painless wiring add-on fuse panel from Geno's Garage).
