if this uses a regular can coil like is on a auto,youll be money ,time, and agravation ahead by simply walking into any parts store and telling them you want a 12 volt coil that uses no ignition resistor. if you dont want to go this route no one here can say unless we know the resistance of your existing coil,OR the new one you buy since yours is likely now bad. the idea is to simply limit the amp draw on your coil to a level it can handle without over heating. you typicaly will want a amp draw of around 3.5 amps or so on your ignition for long life and performance,so youll want a total ignition circuit resistance of around 4 ohms.this may be high a little but your alternator is putting out around 14.5 volts instead of 12. if you calculate it on straight 12 volts youll want a resistance of your total ignition circuit of @3.5ohms .so measure your coil(its MY opinion you should buy new as i believe once one overheats and tractor dies youve damaged it, but you could get by possibly) between the two small posts,find a external resistor to make your total resistance in ignition circuit between 3.5 and 4 ohms and you should be pretty close. as you can see, a coil that needs no resistor is far less complicated far less connections to go bad etc,but its your call .thats the theory behind the resistor anyway, i hope this helps!

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I�m handing him tools and he says, "give me that..." and I�ve already got it in his hand or "hand me that....."and I�ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th
