Bi-Fuel Relay Module
WARNING: This page is about a different car, the 2002 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The bi-fuel relay module contains 2 replaceable fuses. Fuse No. 1 (3-amp) protects battery feed (BATT) to compuvalve. Fuse No. 2 (10-amp) protects BATT feed to bi-fuel power relay which protects VPWR circuits of compuvalve.
Bi-fuel relay module also contains 2 mini ISO relays: the bi-fuel power relay and fuel pump cutoff relay. Bi-fuel power relay provides power to compuvalve when ignition is on. When ALT/GAS fuel switch is placed in ALT position, fuel pump cutoff relay interrupts power from gasoline fuel pump relay to gasoline fuel pump.
