Need help on electrical system on 730 pony ignition

Jf family · Nov 14, 2009

I have a 730 Diesel John Deere. I needed to replace the distributor on the pony engine which includes the two small coils. I purchase the entire unit and replaced it. In the box with the new unit was a small wire coiled about two inches long and then a one inch straight ends on it. I have no idea where that goes. I looked through the old one and there is nothing like that in it.
Any help anyone could give would be greatly appreciated.

Thanks.

Im not sure, but some of those tractors had an ignition ballast resistor (small coil of wire basically) up on the ignition switch which dropped the 6 volts down to the 4.5 to 5 volt range to power up the pony distributor. Perhaps thats what is for?? See if it has like maybe .25 to under 1 ohms resistance?? Many guys no longer use that ballast when they replace the old style with the newer pony coils.

I havent owned a 70 or 720 for years that had the pony so NO WARRANTY on this guess
