2000 coil replacement question

If you are technically minded, a real 6 volt roundcan ignition coil will measure about 3 ohms and a real 12 volt coil will measure about 6 ohms. Exact values not critical for determining wheather 6 or 12 volts. Difference is about a factor of 2. Understand?

On the coil, (+) to battery (+), and (-) to battery (-). That means if your tractor is positive ground, then the coil (+) goes to the points which are "grounding". Understand?

Lastly, a real 12 volt coil on a real 6 volt battery system ain't gonnna have 'nuff sparkies to even knock ya on yer buttt let alone light off your engine.

I'm very suspicious, based upon your reports, that you DON'T HAVE a 6 volt coil..... .Dell

I should have been more explicit and said: there are some "Ford/New Holland dealers" selling a generic 1-size fitts all, roundcan ignition coil as a 6 volt coil that is labled for 12 volts and sez: must be use a resistor. And then the electrically challenged mechanic trys to use it on a 6 volt system WITH a 12 to 6 volt converting resistor, and wonders WHY his new ignition coil don't gotts NO SPARKIES????

So the general rule is: IF the coil primary resistance is about 3 ohms, its a 6 volt coil and use NO resistance. IF the coil primary resistance is about 6 ohms, its a 12 volt coil and ya gotta get a different one 'cuz it'll never work on 6 volts..... .....Dell
