D17 Eating points

Points burned up and I knew regulator was bad so I changed regulator, points, condenser, rotor, etc. Now a week later, new points burned up. Any clues?
 
You stand about a 95% chance your condenser is bad. A condenser is a spark buffer for the points and when bad it causes the points to burn up very fast

Thanks Old, I changed it also; but, wouldn't be first time I had a new one that wasn't good. I'll try a new one. Have a great day.

If tractor is 12 volt and you are using the wrong coil that can also burn points. You need one that has built in ballast resister with about 3 ohms resistance, or an external ballast resister that will accomplish the same. Kip
 
I tend to agree with Old there, an improper sized or bad or bad grounded condensor can cause premature point failure BIG TIME.

Overcurrent can also cause premature point failure, so if youre at 12 volts make sure you have EITHER a full true 12 volt coil (some call internally ballasted) OR ELSE if a 6 volt coil then a series voltage dropping (12 to 6) external ballast resistor wired after the ignition switch and before the coil. NOTE if you run a 6 volt coil at 12 volts (i.e. no ballast resistor) it will get HOTTTTTTTTT so hot you can barely lay your hand on it once warmed up PLUS burn up the points quickly......

if voltage is staying on the points it will burn them up or no resistor or bad resistor between the coil remember 6 volt points sometimes 12 v hot coils get em. then again d17 are newer than wds so they may have had 12 volt system from factory im not for sure if they did disregard all that if they came with 12volt systems.
