Charging-system health monitoring
The regulator doesn't just charge — it learns the output your alternator should make for a given RPM, field, battery voltage, and temperature, then flags when performance starts to deteriorate. Early warning of trouble, long before it becomes a dead battery at anchor.
How it works
While the engine runs, the regulator continuously logs what the alternator actually produces and learns the output it's capable of at each combination of RPM, field excitation, battery voltage, and temperature. That becomes a reference for your unit on your boat — not a generic spec sheet.
From then on, live output is compared against that reference. A meaningful shortfall — less current, or more field needed to make the same current — reads as deterioration, and the regulator flags it.
— live output vs. expected
Live health: how today's output compares to what your alternator should make.
It watches the whole charging path
Because the reference is built from real measurements, a shortfall can come from anywhere in the chain — so we call it charging-system health, not just "alternator" health. It reflects:
- the alternator itself (worn brushes, a failing diode, tired windings)
- the regulator's field-drive stage and field circuit
- the sensors feeding the loop (a drifting sensor reads as a fault — which is itself worth knowing)
- the belt and mechanical drive
Degradation trend + life prediction
Plotted against engine-hours, the health number becomes a trend line: a healthy system holds a roughly flat line, and a steady decline is the early warning. A separate physics-based life model predicts time-to-failure from your actual usage, so maintenance can be planned rather than discovered at the worst possible moment.
