This has never happened to me before but my chemical must have gone bad. It smelled so bad and I do not know how it got so bad. Seemed like it just turned over night.
NOOOOO ITS THE RED WIRE!!!!!!
I still do not know what the yellow wire does but I know it is not the motor starter, that is the red wire.
I could not figure out what the problem was today with my high pressure soap and wax and I knew it had to be a Coleman setup misunderstanding. So I called Greg and he answered my question over the phone! The problem I was having was I was getting pressurized water from the water line where I expected gravity feed. Greg explained to me the way the Coleman unit works, it uses cold water at city pressure for rinse and hot water or gravity feed for high pressure soap and wax. My problem was exactly what Greg told me over the phone and was a miswiring. Thanks Greg.
Mark VII makes the most inaccessible self serve unit ever?
I know I am always complaining about my Mark 7 self serve equipment, but it is only when I need to try and fix something. The first picture shows the solenoid and needle valve that brings the wax to the high pressure water. I needed to remove the needle valve, which sounds easy. You just have to take the solenoid all apart and everything is so cramped, it is just terrible. The second picture shows; on the left the high pressure soap solenoid valve and on the right the wax solenoid valve. The high pressure soap it under the motor and is even harder to get to then the wax. I hope that Mark 7 has changed some of this layout. But I guess the previous owner could have did this?
