Good morning,

Needing some help troubleshooting

Having trouble with the rear ride height too low.
Sometimes the mudflap is 6" off the ground, sometimes 1".
Hadley system will lower but will not raise the coach even though the green lights are on.
I'd like to know where the Hadley system gets its rear level reference from. There is no rear mechanical leveling valve on the rear suspension but the front suspension has individual mechanical leveling valves.
There are several little short magnetic antennas placed on the frame in the front, on the sides, and rear of the coach. Not sure if they anything to do with the Hadley system, or a tire pressure monitoring system?
It always shows the orange low on the rear HWH leveling system control panel.
Thanks in advance for any advice or help.
