☀ Solar BMS DiagnosisStep 2 of 4
Check the BMS protection fuse. Is the fuse intact?
The BMS protection fuse is located in the fuse holder on the BMS input cable, inside the saloon bilge. Pull the fuse holder and inspect the fuse element — a blown fuse will have a visible break in the wire. Replace with the same rating fuse from the spares kit.
AFuse was blown — I have replaced it.BFuse is intact — BMS still not powering on.CI cannot access the fuse.Battery
