Wisconsin troubles - fries points

[ohiocowboy1277]

hi all I seen this ad on craigslist and and shot the guy an email sending him here for advice this was his question :

I have a wisconsin 12 horse engine with a coil ignition that fries the ignition points when trying to start.cant find any shorts anywhere. replaced points and condenser at $40 and it still smokes and heats the points and looses the spring tension so they won't close. any ideas? please help

anyone have an idea that might cause him to have this prob?

You need a resistor coil. There is too much voltage going to the points. You can use a resister coil or install an external resister btween the coil and distributer. You need only 6 volts to coil. You must have a 12 volt system?

after talking with the guy i went over to take a look at what he had and discovered the coil was wired backwards so i hooked it up the right way and it fired right up it was converted to 12v and already had a resistor in line but was hooked to neg. side as soon as i reversed it and replaced the points it was running great . Im glad for that as this is the first wisconson ive ever seen and worked on only ever seen pictures of them before this so it was a great moment to see one of these oldies in person and hear it come to life . now i gotta get one when i get some money lol i dont know why or what ill do with it but still gotta get one im sure you guys know the feeling though . thanks for the help
