| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | Habitation battery charging status is very low | — | The leftmost LED on the display bar starts flashing to show the habitation battery needs charging. | DIY Safe |
N/A | Alternator isn't topping up the habitation battery while driving | — | Work through this checklist: check the 50A fuse feeding the ancillary battery near the starter battery, check the 40A fuse feeding the combined unit, confirm the 'motor running' signal is present at the input module, and confirm the SMP 439-10 combined charger/booster is actually active. | DIY Safe |
N/A | Battery sensor has lost its voltage reading entirely | — | You'll need to recalibrate it by hand: make sure nothing's drawing 12V power, open the battery circuit breaker so the superstructure electronics switch off, then leave the sensor to calibrate itself for roughly three hours with no 230V mains connected. | DIY Safe |
Frequently Asked Questions
Q: How do I switch all 12V devices and the system-controlled 230V devices back on after first connecting to the 230V mains?
Press the main switch, or press any other control key instead, to bring every 12V device and every system-switched 230V device back online.
