Kill switch 47 cub 6 volt battery ignition

Postby RedTom » Thu Nov 09, 2017 2:29 pm

If the lights are off will leaving the switch on run the battery down. You can tell I’m a newbie since if haven’t tested this by experience. Trying to decipher the wiring diagram it look like off breaks the circuit through the ignition coil but is there a drain if left on when the engine not running?

Yes, there is a drain on the battery if the ignition switch is left on with the engine not running.
I have an excuse. CRS.

If you have a 6 volt ignition system as opposed to a mag then yes - like Eugene said. If it is a mag then the switch you described as a kill switch is exactly that, it shorts the mag to ground and kills the spark. That said - a 47 Cub had a mag originally (yours may have been changed to a regular coil system). A mag makes spark independent of any battery you may have and uses no battery current.

Yep - it will certainly run the battery down. I've done it too many times, unfortunately. :(

:wink: Appreciate all the replies. Since the magneto has been replaced I’ll remember to call it an ignition switch instead of a kill switch :thanx:

It's good to keep in mind that if the ignition is left on and the points happen to be closed it can overheat and damage or even destroy the coil.

Yup, fried my coil once that way.

Doesn’t do the points any good either. Can take the temper out of the points spring along with burning the contacts.
