Neutral Relay Inspection

Inspect the neutral relay in the following procedures:
1) Remove the neutral relay. Refer to "Neutral Relay
Removal and Installation (Page 1I-7)".
2) Check the insulation between "A" and "B" terminals
using the multi-circuit tester.
3) Apply 12 V to terminals "C" and "D" ((+) to "C" and (–
) to "D") and check the continuity between "A" and
"B". If there is no continuity, replace the neutral relay
with a new one.
