So today I started digging more and poking around with the old volt meter. In the cabinet, curb side bed room, full bed. I find this box with a switch.
This switch will turn the compressor on when everything is hooked up. Behind the box I found the pump and pressure switch and also a solenoid.
The solenoid was energizing as soon as I hooked up the battery causing my 12v
@ almost 1 amp draw. I looked though the book and found the hot wire on the solenoid starts at the fuse panel in the dash. It is just hooked to a constant power supply without a fuse.
Once I pulled this wire from the solenoid my power draw went away. Also the switch no longer worked when the wire was unhooked. My book says that the pressure switch is set for 85 pounds and should shut off at 100 pounds. I have 65 psi in the tank.
The pressure switch remained close the whole time regardless of power.
So now I wonder what is wrong here. Why is the a additional switch for the compressor? Why is the solenoid getting constant power? Could it be because my pressure switch is bad and won't open? Ahhhh the fun of a new project.
