The legacy circuit breaker box houses seven [7] 30 Amp auto resetting circuit breakers (always
check for a failed breaker prior to replacing the entire circuit breaker box) however if the box fails
it must be replaced with the current circuit breaker box. This requires a new mounting bracket
and harnesses which must be ordered by contacting Hale Customer Service (800-533-3569) and
providing the information from the systems ID tag. Refer to the SAM OIM (FSG-MNL-00210), SAM
Numbering and Specifications References (paragraph 2.1), Hale ID Tag With Sample Markings
(Figure 1.) for details.

Circuit Breaker Checks
All SAM circuit breaker box (and legacy CB junction box) use auto-reset breakers. Perform the fol-
lowing to check for a failed breaker verses a short circuit condition.
A.
Isolate harness wiring from circuit breaker as follows.
If legacy CB junction box, perform following.
a)
Remove junction box cover.
b) Tag and disconnect wires at suspect circuit breaker.
(Bus bar removal is NOT required.)
If current circuit breaker box, perform following.
a)
Tag and disconnect electrical connectors.
b) Use cover label (see Figure 84, page 115), Figure 85 (page 115), and Table 66 to de-
termine associated connector pins.
B. Set multimeter to check continuity. (The continuity setting is typically indicated by
a microphone symbol.)
C. Check for continuity as follows.
Place negative multimeter probe on one circuit breaker terminal (or connector pin).
Place positive multimeter probe on other circuit breaker terminal (or connector pin).
Listen for tone. (Also look at the reading on the multimeter, it must be near 0 Ωs.)
D. If there is NO tone (and much greater than 0 Ωs displayed), replace the associ-
ated circuit breaker. (See the applicable procedure above.)
4.10.7 SAM Tablet
DO NOT HARD SHUTDOWN THE TABLET (POWER OFF BY HOLDING THE POWER BUT-
TON FOR LONGER THAN 5 SECONDS). A HARD SHUTDOWN MAY CORRUPT THE OPER-
ATING SYSTEM, MAKING THE TABLET UNUSABLE.
To check the tablet charger (Figure 89), perform the following.
•
Check for constant 12 VDC power and ground at source connection (location may vary).
•
Check for blown fuse at tablet power supply converter.
