Ballast resistor

[SteveR(OH)]

Need opinion. Tractor is converted to 12 volt but I don't think there is a ballast resistor. I burned out a coIL that was not very old, and said right on the side no resistor required.

Do I need one anyway?

Front coil or side coil?

It makes a difference.

stever.......In the days of before Die-Hards, batterys died eazy. Ford used an electrical trick called a ballast resistor to compensate fer that known weakness. Round can coils are generally bullet-proof. Iff'n yer roundcan coil burned out, guess what, it was 6-volt coil being operated on 12-volts. Lotta bubba conversions use the $3 el-cheepo trick of 12-to-6 volt converting resistor 'stedda $14 12-volt roundcan coil. Unfortunately fer electrical nuiebies, ALL resistors look alike.......Dell, who has an FCC 1st Class License so I know a little bitt about electronics

Dell, I'll see your 1st Phone and raise you a ship radar endorsement. Long ago...

Back around 1958 I too had a first class FCC license with ship radiar endorsement, but technology has changed so much that today I even have trouble using a smart phone....... Never did learn how to progrom my VCR. LOL

did u ever watch the Red Green Show, mike?
one day, harold was reading a letter from a lodge member which said:

hey guys, i've figured out how to make your VCR stop blinking 12:00 all the time! unplug it when you're done using it.

ok. Will get another coil. Thanks All~!

Make sure you get a 12 volt one. Side mount dist machines do not use the ballast resistor.

Why are you getting another coil? How do you know it's burned up? Side coils are nearly bullet proof.
