Hello prd, Mark electric and Gadge,

I've tested the black wire and black/white wire on the Honda solenoid, it still works.

I had a look at the electrical diagram that came with the PDF Honda Motors, I can't follow those diagrams.

The diagram that Mark made / modified is easier to follow.

Would this be correct.

M on Key switch connects with Magneto wire from Honda Mower.
G on key switch goes to Earth.
B on key switch goes to Battery via Positive terminal on Honda Solenoid.
L on key switch is not used as there are no lights.
S on key switch goes to Honda Solenoid......Is it the same positive terminal the battery lead and B lead from key switch connects to?

At this stage all needs to be done is having a charge wire installed somewhere to recharge the battery. What amp wire would you recommend?

Still not using Safety Cut off Switch (at this stage)

Cheers, Bondy
