Another compressor problem

[bubblerboy64]

I haven't had a chance to look into this today as yet. I appeciate
the help to this point. My question is what regulates the
compressor? The pulley is spinning all the time but I can tell by the
sound that it cycles on an off as far as a load.The compressor
mounting rattles rather noisily when it is changing the tanks. Does
something close and open to fill the tanks? I have this idea again
perhaps I am wrong that this is electrical? Or as Gregory said there
is a valve sticking. Now where are the valves? In the top of the
compressor. Remember this thing is bits and pieces of parts so that
makes it even more interesting. I had this occur before one time and
my shore batteries were down. I got the batteries charged up and the
compressor kicked in. Could be just lucky or a coincidence? Seems
like a leak would leak all the time rather then come and go. I plan
on fooling around here today with it so I will be back and forth. I
guess the first thing I will do is just start the bus and try again.
I need to figure this out because at some point its going to stay
broke. Likely at the worst possible time. So I need to understand
the system a little better.
