In addition to what John T said. Not all of the 50 models originally had a by-pass starting system with the resistor. I think the parts book shows a serial number break,but it could of been rewired and added to any of them.

My 50 is a late one with the bypass starting wire and ballast resistor.

I have been known to forget to turn on the ignition switch, just hit the starter foot switch and it starts right up, but stops as soon as my foot comes off the switch. It doesn"t have the extra ground mentioned. Then it"s a quick glance and OH YAH I need to turn on the ignition switch!!!

That's been my experience Mike, many were like the 520 (ballast and by pass circuit) others not why I added that disclaimer (moreso on 520). I guess if he has 4 wires (2 on each side) it must be wired like the later 520's. I've also seen different switches at vendor booths, the 20 series needs the MAG or GRND terminal for this purpose and that switch can also be used as a kill switch for a Mag ignition tractor as it provides a ground when OFF.

Were getting pretty detailed on this one but Ive seen this question raised before.

Fun chattin at ya
