Air System

2009 Holiday Rambler Scepter 42pdq. Front tank air pressure gauge reads normal around 135 psi but rear tank pressure gauge reads around 95 psi. There are no leaks in the system checked it out. Cannot find a diagram to show me where to look for pressure sensor. I checked pressure on both systems at the 2 front portsmark front and rear tanks in the front of the MH and both are reading around 135 psi. I believe there's only one air tank on the MH??

Sure sounds like a bad sensor. Look on the brake treadle valve (firewall side) - that is a common place to mount the pressure sensors.

You probably have three tanks (sometimes one tank is divided internally to make two tanks, in which case it would look like the coach only has two tanks).

The compressor pumps into the first tank called the Wet tank, then there will be a primary and secondary tank (the air system is divided into two part (primary and secondary) and each system operates independently so if there was a failure of one system the brakes will still work off the other system.

So, you are hooking up your portable gauge to the bottom two drain ports on the drain manifold?
The top two are both wet tank. One a supply for air'ing tires etc, the other, a wet tank drain, and hookup for a tow truck.
