✓
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
