805B, MEP-815B, MEP-806B, MEP-816B
The MEP-805B, MEP-815B, MEP-806B, MEP-816B, models of the Tactical Quiet Generator
(TQG) family of generator sets have a readiness problem. The problem is the loss of DC control power
during mission operations. The power loss is caused by a blown fuse located in battery charging circuit
between the alternator and the batteries. While the generator set is operating, the source of the DC control
power is the battery charging alternator. When the fuse blows, the source of generator set DC control
power becomes the batteries until available battery power is consumed. With no DC control power, the
generator set shuts down. This modification is designed to eliminate the battery charging fuse from the
DC control power circuit. This will prevent generator set shutdown and mission failure due to drained
batteries. These modification instructions are authority to modify the generator set until the formal design
change documentation is approved and disseminated to the field.
6.5.2 Parts Required:
6.5.3 Repair Procedures:
The following procedures are designed to allow the soldier to disconnect the control power from
its current location and move it to the positive terminal on the battery-charging alternator.
1. Disconnect the batteries in accordance with BATTERY CONNECTION INSTRUCTION PLATE,
figure 1, located in the battery compartment.
Figure 1 BATTERY CONNECTION INSTRUCTION PLATE
2 Remove wire # 165C16 from the positive terminal of batteries as shown in figure 2.
