2.6 Optional Voltmeter/Ammeter Installation
An ammeter (AM-1) or voltmeter (VM-1) can be installed for use with the CHG-75
charger. If installing an AM-1 or VM-1, mount the meter to a BB-26 or BB-55F battery
box as illustrated below.
VM-1 Voltmeter Connections - the VM-1 can be installed on the CHG-75 to provide a
visual indication of the battery/charger voltage. When the battery is disconnected, the
voltmeter measures charger voltage only. The VM-1 can mount to a BB-26 or BB-55F
battery box. To connect the VM-1 to the CHG-75:
✓ Connect the VM-1 positive lead to TB2 Out (+)
✓ Connect the VM-1 negative lead to TB2 Out (-)
✓ Mount the VM-1 into a mounting slot on the front of the battery box
AM-1 Ammeter Connections - the AM-1 can be installed on the CHG-75 to provide a
visual indication of the charger current. The AM-1 can mount to a BB-26 or BB-55F
battery box. To connect the AM-1 to the CHG-75:
✓ Cut jumper JP5 on the CHG-75
✓ Connect the AM-1 harness to connector J4 on the CHG-75. Be sure to
observe polarity
✓ Mount the AM-1 into a mounting slot on the front of the battery box
