Got a little 1050 that keeps burning the points after a few minutes.I have looked at everything and can not find the problem.Changed the key switch,regulator,stater generator,coil and so on and can not find a grounded wire anywhere any thoughts.

Did you try the condenser?

If the condenser is the correct one & good, then you may have a non resisted coil on there (or coil going bad). Got a ballast resistor to add, or a different coil?

Yea i put in new wisconsin points and a new wisconsin coil.But i will have to check that i grabbed the correct points and condencer off the shelf.This thing just has me baffled.

Is there a difference in condensers when using magneto or 12V coil?

I wouldnt think so...
Some of mine used to run on magneto's but I converted them to coil's without changing the condensors and have not had any problems...

Some thing is causing a high current at the points or an arc due to a condenser issue.
Coil Low resistance or bad or improper condenser.

From what I know if your burning up your points there's to much current going though them, like olcowman says put a resistor in the circuit to cut done the current. The condenser acts like a buffer, reduces the arcing when the points open and close, the more current the more arcing, may need different condenser for different current's??? "just my 2cents worth".

Just my 2 cents worth.
I coil that requires an external resistor has a primary resistance in the area of .2 - .5 Ohms.
If it is made to operate with out an external resistor you will see a primary resistance of about 1.2 - 1.8 ohms.
When checking a system with and external resistor you should see a voltage drop of 6-8 volt across the coil primary and the remainder of the system voltage drop across the external resistor. For example system voltage with engine running = 13.7 volts. Voltage drop across coil = 8 volts thus the voltage drop across the resistor will be 13.7 - 8 = 5.7 volts

If there is a short inside the secondary, effectively reducing the number of turns, then the secondary voltage would be lower causing the current to be higher. I don't know how likely that is or what kind of resistances you'd be looking for, but if you have several to test you could get an idea what to look for.
