You have a wire (red 10ga) going from back of altinator to the inside of the cab to fuse box. This also goes to the siloniod. They all should be 12volts .
The ground for the siloniod is the body that it mounts to(inner fender well). Another wire comes from the steering column to the siloniod to open the contactor to start the motor. You should not have 12volts+ starter side of siloniod. With the battery not hooked up put the volt meter on continuity or Ohms and see if there is any fuse or wire going to ground. Also make sure all your negetive wires are going to ground (frame/motor)
There is also a fuse block in the wiring it is a black cylinder looking thing if it is blown you will never get 12 volts+ untill you cut it out and replace it with a water proof fuse.This is on the Red 10 ga wire going from the altinator to the inside of cab.
Also check the voltmeter in the dash and make sure it is hooked up . your 12volts+ runs through it.
