Laitch,
Looking at the diagram you posted, I removed the black wire. Ok, I know, there are two depicted on the diagram. So, lets number them and then I will describe what I did.
On the Starter Relay there are four posts, lets label from the left to right; 1, 2, 3,4.
On the Starter Motor it depicts two "wires", but from left to right, we will have wire 5 and wire 6.
Now, we know that wire 6 does not technically exist as this is the ground from the starter motor body.
So, this is what I get when testing with a voltmeter and how I jumped the wires.
Key off:
Wire 1: 12v positive
Wire 2: 12v positive
Wire 3: 12v positive
Wire 4: 12v negative
Wire 5: 12v negative
Starter button pressed:
Wire 1: 12v positive
Wire 2: 0v
Wire 3: 0v
Wire 4: 12v negative
Wire 5: 12v negative
I removed wire 4 from the post and tested the voltage on the wire, it was 12v negative.
I tested the voltage on the Starter Relay post where wire 4 is after removing the wire from the relay and it was 0v. Pressed the starter button, 0v.
Using wire 5, I jumped this across to wire 1 to try to spin the starter motor. This just caused a lot of sparks.
Voltage test of wire 5 when I disconnect the wire 4 from the relay post: 12v negative
I think the starter is shorted out and time for a replacement. The purpose of this, is because all bike was fully disassembled, rewired with a m.unit blue, and now that everything is coming back together, so I am individually checking each component to make sure it still works. The Starter was removed and did end up having a fall from the bench.
Thanks again!!
