Product Usage Instructions
Installing an AM-1
- Mount the AM-1 ammeter into a BB-55 battery box.
- Connect the 3 ft (.914 m) cable of the AM-1 to the charger at JP3.
- Connect the positive and negative leads of the AM-1 to the battery terminals.
Installing a VM-1
- Mount the VM-1 voltmeter into a BB-55 battery box.
- Connect the positive and negative leads of the VM-1 to the charger output circuit.
Installing an MPM-3
Note:
The MPM-3 must be installed with the supplied mounting hardware.
- Remove any original mounting screws from either power supply’s PC board at the MPM-3 installation site.
- Mount the MPM-3 onto an MPS-24A or MPS-400 power supply using the provided mounting bracket.
Introduction
An ammeter (AM-1), or voltmeter (VM-1), or both (MPM-3) can be installed for use with the CHG-120 charger. Refer to Table 1 for descriptions of optional connectors on the charger. If mounting an AM-1 or a VM-1, mount the meter to a BB-55 as shown in Figure 2. If mounting an MPM-3, mount to a power supply (Figure 3) installed in a CAB-3. Table 1 contains descriptions and part numbers for these optional meters.

Installation
Installing an AM-1
Perform the following steps to install an AM-1:
- Cut jumper JP9 on the charger (refer to Figure 1).
- Connect the AM-1 harness to JP3 on the charger (refer to Figure 1). Be sure to observe proper polarity.
- Mount the AM-1 into a mounting slot on the front of the BB-55 (refer to Figure 2).
Installing a VM-1
A VM-1 can be connected across a charger output circuit. For example, to install a VM-1 to measure voltage from charger output circuit 2, perform the following steps:
- Connect the positive lead to TB2 Out 2 (+) (refer to Figure 1).
- Connect the negative lead to TB2 Out 2 (–) (refer to Figure 1).
- Mount the VM-1 into a mounting slot on the front of the BB-55 battery box.
Installing an MPM-3
Perform the following steps to install an MPM-3:
- Connect the AM-1 (refer to Figure 1).
- Connect the VM-1 (refer to Figure 1).
- Mount the MPM-3 onto an MPS-400 or MPS-24A power supply (refer to Figure 3).
Note:
The MPM-3 must be installed with the mounting hardware supplied with it. Any original mounting screws in either power supply’s PC board must be removed from the MPM-3 installation site prior to installation of the MPM-3.
