12v dc ignition switch.

[kevspeed]

Hi all,I'm doing a 12v full dc conversion on my series 1,and have a fuel gauge mounted in the legshield toolbox.
This is going to be permanently 'live' and will drain the battery when the scooter is not in use unless I put an 'isolator' switch on the battery output lead.
I seem to remember that one of the standard ignition switches will do this if fitted correctly,but I can't remember what model it's from......any ideas?
And also any tips on wiring it in would be great,.....thanks in advance....Kev

So the series 1 never originally had an ignition switch. If you keep the light switches etc as standard you can use any of the positions of the ignition switch to switch power....

Ive done this in my S3

It's set up with the tv type switch,but apparently a tv2 ignition switch is the one,so looks like I'm sorted.
