Q: Which fuse or MCB protects which circuit, and what rating should I use to replace one?
Fuses on the PSU (fuses 2-10 have a red LED underneath that lights when blown; the charger fuse has a green LED indicating the charger is working): Fuse 1 (25A, white) - Charger; Fuse 2 (7.5A, brown) - Permanent 12V; Fuse 3 (10A, red) - 12V Sockets; Fuse 4 (10A, red) - Appliances/Fans; Fuse 5 (15A, blue) - Compressor Fridge (when fitted); Fuse 6 (10A, red) - Pumps; Fuse 7 (10A, red) - Light Main & Dimmer 1; Fuse 8 (10A, red) - Light Main & Dimmer 2; Fuse 9 (5A, tan) - Awning/Entry Light; Fuse 10 (10A, red) - En Route/Electric Step; Fuses 11-13 (15A/7.5A/5A) - Spare; Fuse 14 (15A, blue) - Solar (rear fitting). MCBs: MCB 1 (10A) - 230V sockets/cooker; MCB 2 (16A) - Extra 230V sockets/heating system; MCB 3 (10A) - Fridge/Separate Water Heater/Charger/Aircon. Always replace a fuse with one of the same rating - never a higher value, which could damage the wiring harness. If a replacement fuse keeps blowing, do not keep replacing it - investigate the underlying fault and contact your dealer.
