continuity of the components listed in Figure 6-41. Also
see Section 8, Wiring Diagrams.
Figure 6-41 gives resistance readings for functional
components. A zero reading on the ohmmeter indicates
continuity. No ohmmeter reading indicates very high
resistance or an open circuit. A measurement that
varies significantly from the value shown in the table
indicates a

Note: Disconnect the generator set battery before
performing continuity checks to prevent damage
to the ohmmeter.
