  • Keyed On/Off switch
  • My 8N is wired for 12v and uses an on/off key switch in addition to the push button starter. My question is has anyone found a replacement keyed switch that has a "positive" on or off position? What I mean by this is when you turn it on (or off), there's a positive stopping point that "holds" the key in that position until you turn it with an albeit mild force. The one I purchased as a replacement does not have this and any type of pressure or touching of the key will move on its own thanks to the weight of other keys or a very mile bump. Any part references for a replacement would be appreciated.

  • OK, it is after all your tractor and your $$$ so you can do what you want. I have to ask what is wrong with the OEM-type switch? The Ignition Switch doesn't care if system is 6V or 12V so that part is irrelevant. I've NEVER had the problem you say you have with the ignition key slipping to the OFF position with or without extra weight from your jail-house key set. Maybe you have bought those cheap, vinyl covered wire units, Cheena made junkers, but I've had the OEM type in numerous tractors and NONE have had this issue plus are not easily capable of turning OFF on their own. Just saying.

  • The ECH KS6041 is a 3 position switch.

    The ECH KS6040 is a 2 position switch.

    Why do you recommend the 3 position switch for an 8n?

  • If you have a 12V system on your 8N and don't have the single wire alternator, with a two wire switch, it will let the tractor run with the switch in the off position if the alternator field wire and the ignition wire are wired to the same side. You can choke the engine down to make it stop running and the alternator will disconnect. You can use a diode in the field wire to make voltage travel to the alternator, but not back to the ignition switch. I usually go ahead and use a three position switch (with accessories position), and that way I have the charging system and the ignition isolated from each other when the switch is off. Dennis

  • Re: Keyed On/Off switch
  • I do have the single wire alternator. Would you still recommend the 3 post or 2 post switch given I have the single wire alternator?

  • Re: Keyed On/Off switch
  • If you have a single wire alternator, then I'd probably go with the two wire switch, because the single wire alternator is activated as soon as the engine is started and revved a little, and shuts down as soon as it stops turning.
