Voltage Reducer ?????

[Stan Allen]

Have been given a cc 147, been in a barn for 14 - 15 years an wiring terrible shape. I am going to rewire but on the + side of the coil wire there is what I would call a voltage reducer?
I believe some older dodge/ply products had them years ago.
This one is about three inches long and screws at each end with a little strip/coil of metal running through it.
What and should I put this back in my new wire?

Figured could get some info on here about this!


Thanks in advance!!!!!

If some previous owner replaced the coil with some aftermarket coil, it may have needed that resistor to control the supplied
voltage to the coil. For testing purposes, you can bypass it and run straight to the positive side. Just be aware that it may overheat the coil so don't run it like that for long. You can monitor the temp of the coil by touching the back of your hand to the "canister" part. The original coil didn't need an external resister. But there is no problem in running it if it works as intended!

Ballast resister.

Instead of having a "cobble job", fix the tractor with the correct parts.
