Charging,?.

["Slack Alice" Simon]

I would rig up temporary connections if they are not already there:

I assume there is a battery lead directly to a place on the crankcase - usually a gearbox stud.

I would take a wire from here to the earth on the control box, one to a dynamo mounting bolt.

Those are the earths involved in the charging circuit - the chassis or body shouldn't come into it.



For the rest of the electrical system I try to run a separate earth wire from every component back to a commom earth point - I have one under the rear seat and one by the control box, and thes points are in turn connected the the main battery earth.

Whilst the original earths to body or chassis are still there, I don't rely on them.   I think the only thing without a separate earth is the horn.

Cheers

Simon
