NOTE
Ensure FRS 24 VDC electrical system is functioning properly.
Ensure MASTER DISCONNECT and 24 VDC panel switches are in the ON position for
voltage checks (TM 9-4940-568-10).
Check for proper ground inside junction box (1) for DC rechargeable handlamp charging station (2).
If proper ground is found, go to next test. If ground cannot be found, repair or replace
ground wire from junction box to DC rechargeable handlamp station (see schematic
Figure 2-5).
Check for voltage between input wire for rechargeable handlamp charging station (2) and a known good ground.
If voltage is present, replace rechargeable handlamp charging station (Para 3-13). If
voltage is not present, go to next test.
Open 24 VDC panel (3) (Para 3-3) and check for voltage between input terminal position 89 and known good
ground.
If voltage is present, repair or replace wire from output terminal position 89 and DC
portable light junction box (see schematic Figure 2-5). If voltage is not present, repair or
replace 24 VDC input wire to terminal block from generator main circuit breaker panel.
