Karcher 620M Pressure Washer

[Stuart Loveday]

Hi
Have a 620M and stripped it down and rebuilt it after problem and for some reason forgot to taken a photo of wiring connections.
I have a wiring diagram and its in black and white. Can anybody provide details of the colours of the wires that go where.
I have assembled it as best I can from the wiring diagram but the pilot/green light comes on when the switch is pressed and the motor runs but then goes out when I release it.
Any ideas please

Yes there are plenty of videos of the 620M except changing the pressure switch which doesn't shoe electrical connections.

Isn't that how it is supposed to work, squeezing the trigger on the lance alters the water pressure at the switch.

Yes and No.
The pilot light should stay green when you hit the start button. At this point the motor does not run . When the trigger is pressed the pressure switch send a signal to start the motor. The motor will not start unless the on/off switch is showing green.
