My genny is a three lug type. Field and Grd on the can and ARM on the end. No current adjustment screw. Haven't opened it yet so don't know if it is a 2 or three brush.
My amp gauge always reads a slight bit on the discharge side when engine running. I have no lights.
Troubleshooting:
Volt meter on battery reads the same 6.33v after battery manually charged whether engine running or not.
With engine started and around 1200rpm. I put my volt meter across the ARM and grd (either the GRD lug on generator or chassis bolt), I expect to get at the very least 6 Volts but actually measure 0 volts.
If I jumper ARM and BAT at VR I measure battery voltage (6.33 v) at the generator ARM to GRD.
I remove ARM to BAT jumper at the VR and disconnect field wire from VR at the generator and connect another wire to generator field lug and to grd and still measure 0 volts across the ARM.
-My meter is fine. I have a few flukes and Beckmans that I have
used in the field for years.
-All my connections are tight and bright.
-Replaced all old connectors and re-soldered them.
-Wires are not old and cracked.
-Ohm'd out wires from genny to VR and readings show no open readings
My question is, I want to isolate the generator from the electrical circuit and want to make sure that the genny is putting out 6+ volts? I would have thought just running the generator with all wires disconnected and a VM across the ARM and Field lugs on the generator should have given me a reading.
What am I missing.
