Went over to wake-up the GMC to take to a car show. Last time I parked it in the unit, it was raining and I did not place blocks under the rear boggie pins. I noticed the right side rear was all the way down. This is generally not been a problem. Just let the Electro-Level II do its thing and all will be good in a couple of minutes. I have dash gauges for the air bags. When the compressors started to pump the right side pressure shot up to 120# so I turned it off. Then I went out to the air bag and noticed the gauge on the bag showed 120#. I bled it off to "0", and restarted the compressor manually. It shot up again to 120# and I shut it off. I have seen these little pumps go to 160# and still climb. I don't feel comfortable at those pressures so I don't allow the compressor to keep running. Next, I jacked up the boggies and observed that after raising a small amount, the pressure dropped as the air went into the bag. Guess there is a chance that the bag can block off the air inlet if it is all the way down. From now on I will be sure to put the blocks under the boggie pins when in storage. Next item, replace the 'Hold' solenoid valve. Off to the car show at Kingwood Harley Davidson in the morning, Oct 29th.

John,
Occasionally if the 9294 deflates just right, the airbag can fold over the
flillport and become trapped. If you can slide a jack anywhere near the
bogie box and jack the coach up just a little while inflating you should
be good to go.
