Before you start
Gather the appropriate supplies and review the specific equipment manual.
- DC panel circuit list
- Battery monitor
- Notebook
Step-by-step instructions
Set a safe baseline
Record current with known appliances off while preserving vital bilge pumps, alarms and required systems.
Observe the normal overnight trend
Many refrigerators, network devices and safety systems draw power intermittently.
List circuits by function
Map DC loads from the panel labels and document any appliances that bypass the panel.
Isolate noncritical circuits one at a time
Use the normal panel switches and note changes in current without disturbing safety devices.
Investigate the specific circuit
Once located, have damaged wiring or unexplained load diagnosed by a qualified technician.
Safety note
Never disable bilge pumps, smoke alarms or other essential protection simply to make the monitor read zero.
Key takeaway
Small always-on loads can add up to a large daily energy demand.
