I am getting ready to drop the TRA-10D in my D4-10 in place of the TR-10D Wisconsin. The question I have is that the old TR-10D had a coil under the Flywheel and the TRA-10D uses an external coil on the fan shroud. What wires will I need to change to make the engine run?

OK, if I don't brain fart, I might can help.  One, the key switch for the magneto grounds when you turn the key to off, so this switch won't work with the battery powered ignition and you'll need to get a universal tractor switch to power the coil, or you could simply use a toggle switch to power the coil.  What kind of charge system....Delco starter/gen?  If so, then all that wiring should remain the same without changes, as it doesn't run anything through the key switch.  You might post some pics of the existing wiring to be sure nothing has been altered.

Coil conversion, a toggle switch would have to be added unless as Daniel stated a three way switch put in which would keep from having to drill another hole in the dash.

This is all I can post tonight, but can take tomorrow if you need them. Also, can I just put the on/off switch on the hot side of the starter button and then use the kill wire to power to coil?

The ignition switch is in fact terminated to ground. Can I just put the on/off switch on the hot side of the starter button and then use the kill wire to power to coil?

Yes you can, but the key will work backwards.  Your key switch makes continuity when in the usual off position, so you will have to turn your key to the right to kill it.  The problem with that is 2 fold...1: you may forget when working on it & it's not running, and run your battery dead by turning the key the usual left  2:, you won't be able to remove the key once you turn it off..

I think I will change the switch out for the right one out of one of the parts D4-10s I have.

 

Thanks Daniel.. :thumbs:
