We acquired this car wash 2 years ago with Sonny's tunnel equipment and Wash Pilot control system. Both are roughly 15+ years of age. Recently, communication between them has been sporadic with communication issues. I have spent hours on the phone with the Sonny's/Wash Pilot help desk - which has been helpful. When running a system diagnostic, we find that all systems are active with date and time. Pushbutton controller is at 12am - not consistent with others. We replace communication cable from to eliminate any wiring concerns that may present...that changed nothing. Afraid that this systems life may be coming to an end. Does anyone have any suggestions? Are there replacement PC boards (used) out there? Any and all ideas are welcomed.
