Although I have a kill switch on the handle bar switch block I'm still having the big red kill button. The back cover plate has been cut from an old metal storage shelf , it also has the ignition on/off switch fuse and the 8g inertia switch mounted on the other side
Here is the rear view of the mounting plate showing the main isolator "Big Red Button" the 8 to 20g inertia switch, ignition switch and fuse holder. The "On" cct. has it's own 12 volt power supply operating the main contractor for the traction cct.
