3.7.15 On the 5 & 10 kW TQG's, if not already performed, rotate the slave receptacle so
that the positive terminal is on top. This ensures that the wrench does not short out on the
back terminal of the slave receptacle when disconnecting the battery terminal.
3.7.16 On the 3 kW TQG, Frequency Converters that have evidence of sand or dust shall
be minimally cleaned IAW the following procedure. The Frequency Converter is an
ESDS (Electrostatic Discharge Sensitive) device and shall be handled using all ESD
protective processes/procedures. Cleaning is not required on Frequency Converters that
have no evidence of sand or dust.
1. Inspect the unit for damage. In addition as the unit is disassembled, inspect for
damage and defective components. Damaged units must be repaired.
2. Remove both side covers and top plate.
3. Remove the bottom plate with fan.
4. Remove the bottom side rail then slide the metal shell up from the electronic
assembly.
5. Remove the Control Circuit Board and Capacitor Circuit Board from the sides of
the electronic assembly.
6. Clean the circuit boards using isopropyl alcohol or other electronic cleaning
solvent (which does not attack the polyurethane conformal coating on the circuit
boards).
7. Clean the metal plates/covers.
8. Reassemble in reverse order.
3.8 Air
Intake and Exhaust.
3.8.1 Air cleaner elements, breather filters, and rubber seals shall be replaced. Clean air cleaner
housing as required. Breather screens shall be cleaned or replaced. Exhaust muffler shall be
inspected per the appropriate TM. The 2 kW MTG and 3 kW, 5 kW & 10 kW TQG mufflers
shall be inspected for clogging and excessive carbon buildup. Clean, repair or replace all

back of J15 inside the bottom of output box.
3.9.2 On the 5 and 10 KW Mil Std sets, verify/test Convenience Receptacle (CR) voltage/polarity at all
three generator output voltage connections. On the 5 and 10 KW Mil Std sets, verify that the CR `HOT'
is wired to the circuit breaker than verify that the other side of the circuit breaker is wired to terminal L3
on S6. Verify that the CR Neutral is wired to terminal 6 on S6. And verify that there is a AWG #4 jumper
wire on S6 between terminals 6 and L0.
3.9.3 On the Mil Std sets; the convenience receptacle shall be replaced with a GFI type, NSN TBD.
3.10 Electrical Harnesses and Cables. All
