I'm working on a 730 diesel for a friend,
the charging system isn't working and
hasn't for a long time. First off I DO have
a JD service book and have been studying
the wiring schematic and understand this is
a 12/24 split load system, the problem is
the generator light on the dash will not
come on, the bulb and socket is good as
well as the switch, I have tested those. I
also had the generator tested and checked
at a reputable shop. I have also cleaned
the contacts in the regulator but need
advise on how to test that and what voltage
readings I should get at which terminals. I
have also found if I unhook the wire from
the gen light (the one that goes to the two
white wires) and leave the other hooked to
the gen terminal at the switch and run a
jumper wire to the one I unhooked to the
positive battery terminal that goes to the
starter I can get the gen light to come on
and off using the ignition switch. Any help
and advice would be greatly appreciated.
