Heres a detailed step by step procedure to diagnose the cause of Non Charging and in Para 5 how to determine if the problem is the Genny versus the Voltage Regulator, or manual Low High charge control in your situation....My Motor Test also tells how to bench test a genny

The Field circuit consist of coils of wire around a soft iron core on each side of the genny. Passing current through those field coils produces an electromagnetic field in which the armature rotates thus inducing voltage into the armature windings. Therefore the Field circuit must be continuous and cant work unil the FLD post has a ground either via a voltage regulator or a Low High manual control switch such as the LHDB switch on the dash which must ovbiously also be well grounded.

In my Seminars and Workshops I spend at least an hour explaining all this and cant cover all that here so post back any questions and read my procedure which may help

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract. ... [Read Article]
