Autometer Knows
Autometer said they had a batch of bad glass. I thought it was only on the ultralite pyro though. I'm going to install my 5th one soon. It's here, I just need to find the 15 minutes. I bought mine at Advanced Diesel Technology and they've been really good at customer service so far. Sent me all of the replacements free of charge, I just send tho old one back after I change it. Autometer does know about the problem and I know there's a 1 year warranty on the gauges, but they might extend it because of the known problem. Good Luck
