Starter Switch Test
1. Set DMM or VOA meter to “Diode Test”
position. In ths position the meter will emit a
continuous tone, indicating continuity (complete
circuit). No continuity (incomplete circuit) is
displayed as “OL” and no tone will be heard.
2. Set meter to Ohms position and set selector to Rx1
scale, when required.
3. Zero the meter.
4. Test switch as shown in Fig. 12. With switch lever
in “RUN” (A) or “STOP” (brake) (B) position, there
should be NO continuity.
