Dave,
The box that Michael is refering to is the limit control switch and has to set screws on it.
If you open the box you can set one screw to start the the compresor at 70 pounds of less and the other is to set the off preasure which should be 90 pounds. If the limit control switch is bad it could be causing the compresor to go on and off for short periods like you are suggesting.
I would try and get the limit control switch checked out and start chasing on item at a time. soap them up good or use the additive that Michael mentioned and replace every leaking fiting you find. Make sure you check the check valves because they get gummed up and will not let the air stay in the tanks. The check valve will let air go into the tank and locks in place so the air cannot go backwords into the supply lines.
It is a time consuming job but it is something that you can track down.
DO NOT GO UNDER THE COACH AND START REMOVING CHECK VALVES OR OTHER FITTINGS WITHOUT PUTTING SOME STANDS OR JACKS UNDER THE COACH. IF YOU TAKE OUT OR LOOSEN THE WRONG THING YOU CAN DROP THE COACH VERY SUDDENLEY, WHICH COULD BE TRAGIC.
