Shampoo Combo Vac - Need wiring diagram

[RichG]

Does anyone have a wiring diagram for the Shampoo Vac Combo? I have an intermittent problem and want to use it to trace down the issue.

What is the Mfg of the equipment you need help with?

It is made by Jim Coleman. It is the version with the keypad for use with a SNC system.

You should have received a manual with the vac. I think that it has a schematic. I probably have one at my wash if you do not. What is the problem? I might be able to help without the schematic.
