hi gurus,
i talked to chad on the phone. he said that the supply side is not losing air, but will not raise the rear in travel or leveling mode.
chad, to be sure, make sure your hwh control panel is in travel mode with the key on (green light next to travel). then press the level button on the keypad with the key on and see if you can raise it.
like dean said, when you are in travel mode (hwh system off and key on), the coach should go up to ride height (about 12" high) there are two travel solenoids on that rear six pack. take a screwdriver like dean said and see if they stick to two of the solenoids (one on the top and one on the bottom) which ones may be different. also look on this forum for a schematic of the rear six pack air lines.
if they are magnetized, your two ride height valves should be getting air and will go up to ride height if there is enough air pressure.
if they are not, you need to check with a voltmeter to see if there is voltage at two of the valves.
the same thing in level mode. when you are trying to raise the rear, the two rais solenoids should be opening (screwdriver sticking to them) and then you should be putting air in the rear airbags. likewise for the lower solenoids.
any other thoughts gang?
