TEST OR INSPECTION
Replace switch S6 if open indication is obtained.
Step 14. Connect ohmmeter between 6V battery terminal and STARTER + INPUT binding post. Set
BATTERY CIRCUIT SELECTOR switch S6 to 6V position. Check to see that 6 VOLT indicator DS4
lights, and ohmmeter indicates continuity.
If 6 VOLT indicator DS4 fails to light, proceed to step 15; if ohmmeter indicates open circuit,
proceed directly to step 17.
Step 15. Set circuit breaker switch CB1 to OFF position. Remove lamp from 6 VOLT indicator DS4, and
check filament for continuity with ohmmeter.
Replace lamp if open indication is obtained.
Step 16. With lamp removed from 6 VOLT indicator DS4, check for 39 ohm ±10% indication across resistor
R2, using ohmmeter.
If resistance indication is not as specified, replace resistor R2.
Step 17. With circuit breaker switch CB1 set to ON position, check for 24 to 30 volt DC indication across coil
terminals of relay K1, using DC voltmeter.
If DC voltage indication is normal, replace relay K1; if no voltage is indicated, proceed to step
Step 18. Set circuit breaker switch CB1 to OFF position. Disconnect leads from one coil terminal of relay K1,
and check for 60.3 to 70.4 ohm resistance indication across coil terminals of relay K1, using
ohmmeter. Reconnect leads.
If resistance indication is not as specified, replace relay K1.
Step 19. With circuit breaker switch CB1 set to OFF position, check for continuity between arm of BATTERY
CIRCUIT SELECTOR switch S6 and 6-volt position terminal of switch S6.
