Installing Optional Meters
You can also order and install a ammeter (AM-1), voltmeter (VM-1), or both (MPM-3) for
use with the charger. If mounting an AM-1 or a VM-1, mount the meter to a BB-55F as
shown in Figure 16. If mounting an MPM-3, mount to a power supply (Figure 17) installed
in a CAB-A3F or CAB-B3F. Table 6 contains descriptions and part numbers for these
optional meters:
Installing an AM-1 To install an AM-1, follow these steps:
1. Cut jumper JP9 on the charger (Figure 15).
2. Mount the AM-1 into a mounting slot on the front of the BB-55F (Figure 16).
3. Connect the AM-1 harness to JP3 on the charger (Figure 15)—making sure to observe
proper polarity.
