My inital concern was the long time to bring the unit up to 60 psi (more then 10 minutes), using the engine mounted compressor. Once it hit 60 psi I could use the accelerator to increase engine speed, and then bring the total air pressure up to 90 psi range and ready to travel if all other issues were OK.
I have had the primary (engine mounted) compressed tested, and it is well within spec, so started to look for leaks in the system. So far found a few loose tubing fittings.
I also thought about using the 120V compressor to provide a boost in the air system, to help look for leaks, and when plugged into land power before starting the engine. Each time (only tried a few) the unit would run for a few minutes, and then shutdown shutdown at 60 psi. I can not find any indication of it being a thermal overload. shutdown.
The '83 also has the similar setup of solenoids, and locations, but I do not have any documents that define the system. I will start looking for the level sensors.
thanks for the input,
Greg
