A thermal scan should be done on all AC components associated with the DC 
power system. 

Perform thermal scans on all battery and DC power connections, DC buss-work, 
and circuit breakers. 

Conduct the following annual maintenance: 

• 

Inspect Batteries: All cable connections and inter-cell connections. Check for 
oxidation at terminal posts and clean as required. 

• 

Check for leaks or seepage at terminal posts and battery jar seals. 

• 

Replace the battery jar if any leak or seepage. 

• 

Torque battery terminal and strap connections nuts and bolts to 
manufacturer’s specifications. Power Battery CSL-12100 Specification is 115 
in/lbs. 

• 

Verify battery voltage and mid-point voltage. 

• 

Perform Midtronics battery analysis using digital battery analyzer (optional). 

Conduct the following semi-annual maintenance: 

• 

Visually inspect all RFS components for loose or foreign items and for visible 
damage. 

• 

Confirm that each component is receiving power (refer to the troubleshooting 
tables listed in 7.3 Corrective Maintenance, next in this chapter). 

• 

Verify that all RFS components are operational (refer to section 5.3.1.2 
Checking the Status of RFS Components). 

• 

Verify coverage validation by conducting spot tests described in section 5.4 
Coverage Validation. 

• 

Verify iDEN functionality by conducting spot tests using the procedures 
described in section 5.6 RFS Functionality Test. 

The fault indications identified in this section provide a guide for isolating failures 
to a Field Replaceable Unit (FRU). The service technician should perform 
troubleshooting whenever a failure occurs during normal operation that cannot be 
resolved by the Operations and Maintenance Center (OMC).
