just curious if anyone has had this issue... when I get into my truck i key the ignition and the pv2 starts up and displays normal. I start the truck and it goes blank and keeps a lighted screen and sorta pulsates a flash on the screen corresponding to the rpm of the engine. Checked all the connections and found no issues. Also discovered on cooler mornings the pv2 would cycle on normal with key and when I start the truck the pv2 would shut down but when the fuel heater or the intake heaters cycled on the pv2 would come on.. as soon as the heaters cycled off the pv2 would shut down. Any suggestions before I contact quadzilla? Also checked voltage inlet to the pv2 and measured 14.2 while running and 11.8 with heaters cycle. This problem just started. the set up has been working great for months now. I installed this set up in the winter and now that its warm maybe the brain is getting to hot and fried something? sorry for the long post just kinda pissed that i spend 800 bucks on something that doesn't work now.

 

Sound like a problem with the unit its self to me.

 

Not sure if u got the problem resolved or not yet, but mine was doing the exact same thing. But mine would always say the boost pressure was at 55 psi when it did it also. It was always related to the grid heater cycling. I sent it back to quad and they said it was fixed but it still did it. I finally gave up and sold it to a friend. I believe it is related to the batteries some how because my friend had it happen to him once when he left his lights on for ten minutes then started his truck. Shortly after I sold it my batteries took a dump and had to replace them. With my new batteries the grid heater wouldnt drag my voltage down like before. I just think between my bad batteries and heater cycling the adrenaline would freak out.
