All,
 
I originally thought my 1951 AC WD was converted from 6v to 12v by my late grandfather.  I now have reason to believe this may have never happend and perhaps it was another tractor that he had converted instead.  So here are my questions:
 
How do I tell if it is still a 6v system or not?
 
Will a 12v battery run the system but prevent it from charging?
 
If it is a 6v system and I put in a 12v battery would that short out my light switch (which doesn't work) but had briefly turned on before it went out?
 
Thank you in advance

If it has a generator, if it has a 6 volt battery, if it has 6 volt bulbs then it might be 6 volts.
12 volts won't hurt the light switch but it may pop the bulbs.  It may also cook the coil without a resistor.  Others will correct me if I'm wrong.  Stay tuned.Wink

I run 12v battery, 12 volt bulbs with a 6 volt generator and 6 volt coil.  The key is the resistor to reduce the 12 volt down to 6 volt before going into the coil.  Confused yet.
