TEST
1. Remove two lock nuts (Figure 1, Item 1) and washers (Figure 1, Item 2) securing battery box top bracket
(Figure 1, Item 3) and L-bolts (Figure 1, Item 4) to lower bracket (Figure 1, Item 5) enough to slip rods free from
lower bracket.
2. Remove bracket (Figure 1, Item 3).
WARNING
Batteries contain high amperage and can explode if short circuited. Never allow any
metal to cross between the battery terminals or between the positive terminal and
any part of the MTRCS frame. Personal injury or death could result.
3. Remove battery box cover (Figure 1, Item 6) from battery box (Figure 1, Item 7) to access battery terminals.
4. Start refrigeration unit (TM 10-8415-222-10, Operating Procedures).
5. Set multimeter to DC volts scale.
6. Measure voltage across battery terminals by placing red multimeter lead on battery positive (+) terminal
(Figure 1, Item 8), and black multimeter lead on battery negative (-) terminal (Figure 1, Item 9).
DC voltage on multimeter should read 13.0 to 14.0 volts, indicating steady and sufficient charge into battery.
If less than 13.0 volts DC is indicated on multimeter, troubleshoot alternator (WP 0004).
7. Remove multimeter leads from battery terminals and turn multimeter to OFF position.
8. Shut down refrigeration unit (TM 10-8415-222-10, Operating Procedures).
9. Install battery box cover (Figure 1, Item 6) and secure to battery box (Figure 1, Item 7) using bracket (Figure 1,
Item 3), two L-bolts (Figure 1, Item 4), washers (Figure 1, Item 2), and lock nuts (Figure 1, Item 1).
10. Tighten lock nuts (Figure 1, Item 1) securely but do not use excessive force that could damage plastic housing.
