200 Series 36V
Controller Power Through Contactor
Use “V” setting on the meter.
Make certain that the resistor has been re-installed if it was disconnected in a
previous test.
Place the black probe to a good chassis ground such as the negative (-) post at the
350 amp fuse or where the ground cable attaches to the frame.
Place the other at the controller’s “B +” position on the cable coming from the
contactor. It should read approximately 30 volts.
Action
If the required voltage is not present, wiring must be traced to locate the item that is
disrupting the circuit.
Additionally, check for a hot resistor across the Contactor. This
indicates a failed controller.
Meter Result
Approximately 30V
Controller
B + terminal (Farthest rearward
