Installing Optional Meters
You can also order and install a ammeter (AM-1) or voltmeter (VM-1) for use with the
charger. If mounting an AM-1 or a VM-1, mount the meter to a BB-55 as shown in Figure
14. 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 13).
2. Connect the AM-1 harness to JP3 on the charger (Figure 11)—making sure to observe
proper polarity.
3. Mount the AM-1 into a mounting slot on the front of the BB-55 (Figure 14):

Installing a VM-1
You can connect a VM-1 across a charger output circuit. For example,
to install a VM-1 to measure voltage from charger output circuit 1, follow these steps:
1. Connect the positive lead to TB2 Out 1 (+). See Figure 13.
2. Connect the negative lead to TB2 Out 1 (–). SeeFigure 13.
3. Mount the VM-1 into a mounting slot on the front of the BB-55 battery box.
