(4) Place and hold ON-OFF load circuit breaker assembly in ON position.
(5) Check for continuity between terminals COM and NO, and terminals A and B.
(6) Remove shrink wrap and check diode assembly CR2 as follows:
(a) Using multimeter, set for ohms, note resistance across terminals. Reverse
leads and note resistance.
(b) Resistance should be high in one direction and low in the other. If resistance
is high or low in both directions, replace entire ON-OFF load circuit breaker
assembly.
(7) Remove and replace entire assembly if any continuity/resistance check is other
than indicated above.
(8) Close and secure instrument panel.
