My turn for the battery problem.

Interesting, I think I had the exact same thing occur, bad relay, then battery no good. I struggle-started it a bunch of times

Hi. If I was to replace, or add in another start relay, It would be able to handle the current expected from the battery. Say 150 amps? Instead of a 30/40 amp relay, Why not use something like...

the thing about the 30/40 amp relay it does not handle the load of the starter
it activates the starter solenoid then the starter contacts take the heavy amp draw about 150 amps or so depending on bike condition
the starter solenoid may be close to 30/40?
 
So, a relay is used to energize another relay? Sounds redundant. Anyone with access to the wiring diagrams?
 
The solenoid is what connects the battery + terminal power to the starter motor. The starter relay energizes the solenoid which is a coil. Inside the coil is a bar with electrical contacts on one end and a spring. When the coil is energized the bar is drawn in against the spring pressure and the electrical contact is closed, putting full battery power on the starter motor lead from the battery and the starter housinng is grounded so current flows from the battery to ground through the starter motor. The amount of current used in the solenoid is fairly low since the only force it's overcoming is a spring. When the starter relay drops out (after engine start) the solenoid is de-energized and the spring then opens the electrical contact shutting off current flow to the starter motor.
