Main Relay (Computer/Fuel System): Testing and Inspection

Control Relay:

Figure 16. Coil L1 & L2:

Figure 17. Coil L3:

1. Check continuity between control relay terminals, Fig. 15, with relay coil energized and not energized as shown, Fig. 16. To energize coils, L1 and L2, apply battery voltage across terminals 6 and 7.
2. Check continuity between control relay terminals, Fig. 15, with relay coil energized and not energized as shown, Fig. 17. To energize coil, L3, apply battery voltage across terminals 8 and 6.
3. If test results are not satisfactory, replace control relay.
