CAUTION:
a. When applying battery voltage to the Control Relay, verify power source connections are to the correct terminals. Otherwise, the Control Relay will be damaged.
b. The following test procedures should be performed in the order instructed. If not, inaccurate results and damage to the relay may occur.
1. Disconnect the Control Relay electrical connector, and remove the relay.
2. Check continuity between control relay terminals, with relay coil energized and not energized as shown. To energize coils, L1 and L2, apply battery voltage across terminals 6 and 7.
3. Check continuity between control relay terminals, with relay coil energized and not energized as shown. To energize coil, L3, apply battery voltage across terminals 8 and 6.
4. If test results are not satisfactory, replace control relay.
