WARNING
High voltages are present at capacitor box. Whenever possible, keep one hand away
from the equipment to reduce the hazard of current flowing through vital organs of the
body. Avoid grounding yourself when touching any electrical components. Failure to
follow this warning can result in personal injury or death.
Capacitors are electrical storage devices that are designed to hold a charge after
power is disconnected from them. For this reason, extreme care must be taken when
working on or around capacitors. Discharge capacitor with a shorting probe before
performing maintenance on capacitors. Failure to comply with this warning can result
in severe electrical shock resulting in serious injury or death.
1. Disconnect battery negative (-) terminal (WP 0053, Disconnect).
2. Remove four bolts (Figure 1, Item 1), flat washers (Figure 1, Item 2), and nylon washers (Figure 1, Item 3)
securing capacitor box cover (Figure 1, Item 4).
3. Remove cover (Figure 1, Item 4) and gasket (Figure 1, Item 9).
4. Discharge capacitors (Figure 1, Item 6) with shorting probe.
CAUTION
Make sure that wires are tagged before disconnecting them from the capacitors.
Failure to comply can result in damage to equipment.
5. Tag and disconnect electrical connections (Figure 1, Item 5) from capacitor (Figure 1, Item 6).
6. Discharge capacitors (Figure 1, Item 6) with shorting probe.
7. Remove hex nut (Figure 1, Item 7) securing capacitor (Figure 1, Item 6) to capacitor box frame (Figure 1,
Item 8) mounting strap.
