R-B3-ISOLATED-RESERVE · FAULT
B3 is the isolated reserve — B3 charges from the system but cannot be drained by other banks. It is the jump/inverter reserve — the contract with the owner.
no path drains B3 into another bank
Luke's brief to Dave [12 Oct] — the contract
VIOLATION
R-CH3-FROM-START · FAULT
Battery input must come from the start battery — BATTERY INPUT + lands on the start battery via a 70A breaker within 20cm of source.
roof_solar split leg 1 + → enerdrive_dcdc Port 2
DC2DC+ manual p15 WARNING + p19/20
BY-TEST
R-LITHIUM-DIODE-DROP · FAULT
No diode isolator upstream of lithium banks — A Schottky diode isolator drops ~0.5V into the charge path; lithium banks needing 14.2-14.4V absorption never reach full charge. Use FET class (~0.1V).
Physical swap — decided by T-FET-DROP, not the diagram
Measured 0.5V [Luke, 11 Oct]; Enerdrive lithium profile [manual p11]
VIOLATION
R-NEG-VEHICLE-SIDE-BSM · FAULT
Input negative lands vehicle-side of the sense module — Smart-alternator vehicles: the input negative must connect to the vehicle side of the battery sense module.
roof_solar array negative → enerdrive_dcdc Port 3
DC2DC+ manual p19/20 note
PASS
R-NO-BATT-ON-MPPT · FAULT
No battery on the solar input — A battery must never feed the MPPT solar input — the charger expects a high-impedance panel array, max 45VOC.
no battery feeds the solar input
DC2DC+ manual p19: max 500W/45VOC
VIOLATION
R-SHUNT-ONE-SIDE · FAULT
Shunt: all battery negatives on B-, everything else on P- — A shunt measures differential current. Batteries on both sides produces garbage readings.
battery_3 negative post → shunt_monitor P-
HardKorr monitor manual p8
PASS
R-STARSHIELD-MANDATORY · FAULT
Starshield 48V converter is mandatory — Starlink Mini runs on 48V. The 12V to 48V converter may never be removed from the feed.
starshield_48v 48V out → starlink_mini power
