Re: schematic

Flips, the kill switch grounds the ignition.<br />It sounds like it is operating normally.<br />To shut off the engine, the orange wire touches ground (at the switch,when switched-off), and the engine stops. The orange wire is at potential when the switch is anywhere but "OFF", and the flywheel is turning.

Re: schematic

Oopps..Schematic, sorry.I really should read the title to these threads.<br />Anyway, Flips. You should have power from the orange wire when the flywheel is in motion. This is normal. I would be worried if you had nothing on the orange wire, as it would indicate a bad ignition. It does not get it's power from the battery (at least not directly). If you left the orange wire disconnected, the engine should start and run just fine...But when you decided to shut the engine off, it would stay running, with the orange wire not hooked-up. This is a good way to test your ignition switch,and safety lanyard switch (if so equipped) for shorts to ground.
