My Ford LGT125 that I started working on today has a K301 engine with the battery powered coil and points.......I think the coil has a crack at the top as it has spark but its flying all over........My question.......Are these coils special to small engines or will any automotive coil that I have laying around work?

I'm pretty shure any automotive coil will work. I'm using a 12volt automotive coil in my Bolens with wisconsin engines and they work great.

I think Brian is correct that almost any external automotive coil would work. They are all triggered the same way, just on the small engines they trigger directly to the spark plug and not to a distributor.

An automotive coil will work, however it will need to be an internally resistored coil, OR use a ballast resistor along with non-resistored coil. If not resistored, the coil will overheat & fry itself, and maybe take the points/condensor with it.

As Dan noted, you need a coil that is designed to take 12 volts directly. You do not have a ballast resistor on your tractor now and I see no real reason to install one just so you can use the 8 volt coils that were common prior to the introduction of HEI (high energy ignition) Bosch makes two lines of coils. The Blue line (part #00012 and the black line (part #00015). The Blue Line coil is their premium model and it puts out almost 50 percent more voltage than the standard black coil but of course, it costs more money. Call your local UAP or NAPA auto parts stores and price them both. NAPA should also have an OEM KOHLER coil available as well. Get them to price that one just for comparison sake. NAPA has a huge Outdoor Power Equipment catalogue so don't let some goofy know-nothing counterman tell you that they don't sell stuff for lawn and garden tractors.

If his current coil is defective, how would he go about determining the original resistance of it?

Just asking. :confuse:

Hey Daniel, wasn't you that posted over on small engine technical forum that the coil needs to be a kohler coil with a internal resistor, I believe it's a 5 ohm coil

Could have been, but I can't remember for sure. I do know ohms makes a difference and best to stick with near same. I usually just go to Autozone & ask for the old style coil for points with internal resistor. I never think to write down the part #.

The only true 12 volt coil for an automobile is from AMC corp.kohler coils are true 12volts as well.

Hope this helps.
