Drawing updated, I have to admit it is getting really annoying to edit a full drawing in Photoshop, especially if it?s a mixed mechanical and electrical drawing that needs to be small as possible to fit on a forum page. :shock: :razz:
Extras in this drawing, after first drawing above:
- As I said the pump is constantly on and will work on its own demand switch but will be off when the water tank is empty.
- Shurflo pumps have external wire for demand switch to turn the pump on, I used that for ?pump on? led.
- Turbo pressure switches will turn on first block-off solenoid and second dedicated solenoid for the nozzle.
- There are two water pressure switches just before both nozzles, these switches will show when there is a clogged nozzle if the led stays on while there is no boost.
- The low-pressure water switch will cut turbo pressure if the water pressure is gone (busted water line).
