46 2N 12v Conv Neutral Safety Interlock bypassed

Thanks!

I would just keep the existing key switch and solenoid, but re-route the solenoid's pull-in-coil wire from the key switch to the original push button. You will have to figure out whether the solenoid uses "ground to start" (like the 8N) or hot-to-start (like most cars).

Just guessing, it's probably "hot to start", so connect one side of the push-button to battery +, the other side to the solenoid. You can use 12AWG wires for this.

Leave the heavy battery cables on the solenoid.

Done in this manner, the push-button never sees the starter current, and merely switches a few amps to the solenoid.

BECAUSE..... to have an ignition key start, the converter would have had to add a keyswitch operated STARTER SOLENOID. (probably a 4-terminal automotive starter solenoid) 2N's did NOT come with a starter solenoid. They came with a mechanically operated 2-terminal starter SWITCH, which is mechanically SAFETIED and remotely operated thru the gearbox neutral linkage by a "jiggle stick".

And while you "could" reverse engineer the 12 volt conversion so you are safetied thru the neutral interlock. There are other ways to accomplish this. AND inaddition, this current conversion may have made use of different switch contacts to prevent the problem of alternator "back-feed" to the ignition coil that prevents the tractor engine from being turned off.

If you don't throughly understand the current electrical scheme, I would be highly reluctant to recommend changing something that is currently WORKING..... ....respectfully, Dell
