meter the g/w wire at the junction box.

put your volt meter on DC V.

black probe on the G/W wire.
red probe on the positive battery post.

what is your voltage?

ok.. you aren't getting +12v to the solenoid.

move the red probe to the yellow/red wire at the junction box
black probe still on negative battery post

press the start button
what is your voltage?

Continuity, no power
I ohmed out the starter relay earlier, 70 ohms on the non broken side, also tried swapping head and start since my start one has corrosion on the outside

ok, your starter button is not sending +12v to the junction box.

find the connector for your starter switch/kill switch..

put your red probe on each of these 4 wires with the
key set to "on"
kill switch set to "run"
do not disconnect the connector

what are your voltages?

I had the starter open earlier to check the connections, 12v on both reds, continuity between all 4 wires
