- Generator Set:
- C175-16 (S/N: WYB1-UP)
Description of Change: The power to the fuel control module was originally routed through a power module.in the control box. The power module has been removed. The +Battery voltage to the fuel control valve is now routed through the engine ECM, which limits the voltage to the fuel control module.
Adaptable To: The change is adaptable to C175-16 Generator Sets back to first production. The change is effective with serial number WYB00428.
Illustration 1 shows the original configuration of the control box, including the power module. Illustration 2 is a schematic of the original circuit, and Illustration 3 is a schematic of the upgraded circuit.
