Stop in for a cup of coffee

The ground doesn't have to be at the battery. Could be anywhere there is a good ground.

Take your pencil and follow the path to complete the journey from the battery Positive to the Negative.
It has to be a full circle for the lamp to light.

That path your pencil followed is what the light is testing. That's it. No more, no less.
Right now, I’m checking my connections at the starter. I hooked this up exactly as I found it on the old one but I’m thinking that may be wrong.

so I have battery cable going from positive to the big stud on the starter, now, there are two addition wires that go up to the starter relay, should they be on the small stud together? The way they are now, one is on the big stud with the main battery cable, the other on the little.
