RE: Weird thing happening with air gauge - rundlc - 04-05-2020

Thanks to all and no apologies needed, DKontheroad has been sending me info via text and has been a GREAT help to me thus far. We were stumped as to why all of a sudden the air valve would go down to zero and the pumps couldnt move the air gauge until I started the engine and then the gauge would start to work.

After starting, the gauge pressurizes and begins to operate normally until the next time I found it at zero with pump running. it's like it needed a boost to get it going again or maybe the "unloader valve" has something to do with it. I dont seem to have any leaks in and or around the dryer valve and or fittings.

Appreciate that Dave is helping via text. Like I posted earlier, our data base on the guru site is light on the newer coaches. I hope that you will help build the experience base by posting what you find. Thanks!


So one approach for a suspect component in the air system is to cobble a temporary bypass to see if the problem goes away. It’s more trouble, but far cheaper than throwing parts at it that you don’t need.

I will do what I can with my limited experience. As I learn more I'll post it up in hope's of helping someone else.
