Fuel Pump Relay
- Power from charging circuit relay runs through fuse/relay box fuse No. 5 and diode box "A" to energize fuel pump relay. Relay is also energized from diode box "A" through oil pressure switch circuit in case of charging system failure.
- When energized, fuel pump relay closes power circuit from main fuse No. 1, through fuse No. 2, through fuel pump relay to fuel pump. See appropriate wiring diagram in WIRING DIAGRAMS
article.
- To test relay, remove fuel pump relay from fuse/relay box on right fender panel. Using jumper wires, ground terminal No. 4 (Black wire) and apply battery voltage to terminal No. 5 (White wire). See Figure
. There should be continuity between terminals No. 1 and 3 with relay energized. If continuity is not present, replace relay.
