[AJD] 420 electrical system

[Ronald L. Cook]

More than likely, the problem is the voltage regulator.  If it is marked 
positive ground then you need to be running a positive grounded system. 
   Or, you could install a voltage regulator that is a negative grounded 
unit.  I would install the battery with the positive ground, polarize 
the generator, and give it a try.  It is supposed to be positive ground 
and I'm betting it will work with no funds expended.
