If you have a magneto and will continue to use it, ignore the ignition system part of that diagram.

I did the conversion on my Lo-Boy some 10 years back and it’s been perfect since.
Paula’s Cub was converted by the PO and it was clear he didn’t have a clear understanding on how to do it as he did install a new coil but it was a 6v. Changing that made the tractor run right but there’s still a voltage drain when parked. If I don’t pull a cable I’ll have a dead battery.
I notice the diagram doesn’t have a diode in the line from the alternator that mine has. It came with my kit. I haven’t taken the time to go over the wiring in her Cub but I’m wondering if there isn’t one on her tractor that it might be contributing to the battery drain.

One other note on the diagram is that most 12v coils have an internal resistor and will state it on the coil so you won’t need the external ballast resistor.

Batt. drain when stopped is usually from the exciter circuit of the alternator not being turned off. IF the wire is not hooked to the right kill wire---it will discharge the batt. ---got a messed up new-holland skidloader that way. I just hooked it to the starter switch, BUT being a Deutz diesel, you still have to remember to turn the key off! lol!! ---some day I might get around to running it a different way, but doubt it!--I just always remember to turn key off!--well cept one time 13 miles from home and no jumper cables with me!, ( long story) LOL!
