Thanks Ross, I'm just trying to get my head around the wiring diagram as the wiring in the unit has been butchered somewhat. Most wires have been cut and rejoined and none have evidence of fuses as noted in the instructions also the orange power wire is not orange but but red and not that heavy and doesn't seem touched so I want to be able to bench test it of sorts before I go to the trouble of starting to set the system up. It does however power up with power on what must be the right wires. The 12 gauge wire to the pump has been cut and lengthened with some very bad soldering so that needs fixing too. I'm thinking I might resolder some fresh wires into the circuit board instead of butchering more.Yes questions are fine, the idea of the thread was to see what is applicable with today, not years ago, if I can answer I will. My low level is made simply through an earth contact in the float switch.
- If I don't touch the float wires then there should be no warning indication on that failsafe?
- I believe the pump is PWM controlled on the negative so instead of trying to resolder a heavy gauge wire into the PCB with shaky hands I should be able to go a lighter (easier) gauge and power the pump through a relay with the power trigger from the PCB. Earth wiring at least is still sound.
Still need a nozzle or 2 and maybe a solenoid if I end up going pre turbo. For simplicity of set up and till I get my head around it fully I might just run the single pre manifold nozzle first. Looking at your set up @geeyoutoo if I set the nozzle up on the underside of the outlet pipe of the intercooler and my tank and pump are definitely lower being under the tray then there is no need for a solenoid on that line.
