ALT Fuel Relay Module

ALT FUEL RELAY MODULE






The ALT fuel relay module contains two replaceable fuses. Fuse 1 (3 A) protects the Battery feed (BATT) to the Compuvalve and Fuse 2 (10 A) protects the BATT to the ALT fuel power relay, in turn protecting the VPWR circuits of the Compuvalve. The ALT fuel relay module also contains two dual mini ISO relays: the ALT fuel power relay and the fuel pump cutoff relay. The ALT fuel power relay provides power to the Compuvalve when the key is in the ON position. The fuel pump cutoff relay interrupts the power to the gasoline fuel pump from the base gasoline fuel pump relay when the ALT/GAS switch is placed in the ALT position.
