Thread: Secondary Fuel Pump activation, reuse for a controller.

  1. #1

    I originally was controlling a secondary fuel pump, using a ground. I don't need the Secondary Fuel Pump now, so I wanted to use it to provide +12V to activate a controller. I went to I/O and switched it to +12V. I notice in the Pin Map, it has a G next to fuel pump. I'm confused if that means Ground or something else, since some of the pinned have an H. Anyway, I lowered some of the settings so I could test it. I can't get +12V to the controller. It's kind of confusing since under parameters, I/O you can configure triggering, but also under I/O, configure, you can also control triggering. Help.

    UPDATE: Think I might've found the problem. That pin, B3, can't be changed, ground only. I'll switch it to ground, and run a +12V to the controller.

    Certain pins can only be certain things. This is what all those letters are next to the pins in the Pin Map. Andrew
