I don't have a diagram, but I've worked on them enough that if you tell me what you're trying to do I can probably tell you how to do it off the top of my head, and I have access to one to study if I need to.
Our carwash tech don’t deal with them anymore they where discontinuedYou need a car wash tech, not an electrician. The contactor is tripping to make you aware of a problem before something bad happens. Chances are low that the problem has anything at all to do with the control wiring which is what the diagram will provide. Maybe a weak connection on control wiring might cause the contactor to flutter, which could cause that, but most likely, you have a motor, contactor, or pump issue and the overload is just doing its job turning itself off before the fan starts stinkin.
it’s for the electrician so I need a diagram or he will charge to get one
basically something keeps blowing the contact and he has never worked on one before
