NOTE:
Safe operation of electrical components requires proper grounding.
In all troubleshooting procedures of components that depend on
screws or physical contact for their electrical ground, use a jumper
wire connected between the component and the hull to check component
operation.
If the component then operates, a faulty ground is
indicated. When such a condition exists, clean the ground contact
surfaces and tighten the screws or repair/replace ground wires that
were found to be defective.

Troubleshooting The APU Fuel System.
Before attempting to troubleshoot the fuel system, the left projectile rack
must be moved to the rear of the vehicle. With the projectile rack at the
rear of the vehicle, the APU access plate removal procedure can be
accomplished.
To remove the APU access plate, remove 10 screws (Item 1,
Figure 10), 10 lockwashers (Item 2, Figure 10), the gasket (Item 3, Figure
10), and the access plate (Item 4, Figure 10).
Be sure to discard the
removed lockwashers and replace them with new ones.
