My 600 bobcat has a Wisconsin motor and I am redoing the ignition. I am thinking I have a bad condenser or coil. It has a ballast resistor and then the coil. Can I just do away with the resistor and run the wire to a regular 12 volt coil?

Maybe. I do not know if the Wisconsin feeds full 12 V on the starting circuit. I'd leave it as-is. All 12 volt coils are is 6 volt coils with the resistor built in. If it would have been such a good idea we never would have had external resistors on millions of vehicles.

I thought there was external and internal resister coils?. only Wis I have left has a Mag.
Asked for a 6 volt coil at Auto zone once, old guy said he had been parts man for over 29 years and never heard of a 6 volt coil. Asked him what the hell you think we were using before things went to 12 volt? 6 volts don't fry the points like 12 would. I would get a internal resister 12 volt coil and by pass the ballast, then check voltage at the points to make sure you have only 6 volts. Only reason I didn't do this on my IH tractors is I liked the original look.
Don't know if this is any help, just my2 cents.

Your man at Auto Zone must have spent his evenings in front of the TV. The coils he was selling were 6 volt all along. They were labeled on the box "12 volt - Use external resistor" so he didn't know any better.

What Ive been told by many is the ballast resistor works like this-when system is energized it will feed 12v then drop to like 8v after a bit its so you dont burn up points.
Ok on another note I have bypassed this setup and it works fine but I think you will burn up points quicker, how much quicker I dont know.
If it were mine I leave it in there. Just my 2 cents :)

Thanks guys, just confirmed that I can go either way but need a resistor coil or ballast resistor.

If you go to NAPA you can buy either an Echlin coil or a cheaper import. I'd go with the Echlin. (and even those may be made in Mexico)
