Battery draining

[Pukmeister]

That's my thinking too - when I get half an hour I'll whip the tank off, disconnect the alternator and see if that makes a difference. Somethings draining current because I get a reasonable spark when I reconnect the negative terminal of the battery.

FWIW my bike also shows a spark when reconnecting the battery if it has been disconnected a while, yet I dont have a battery drain issue.
