Still learning about my relatively new (to me) 850 Commando MK1. Bike is positive earth. Went to replace the battery today and, in the process, the fuse holder just broke off the lead wire. Must have been hanging by a thread. What I believe is likely the original Lucas 35 amp glass fuse was still in it. Fortunately, I had a couple of mini fuse holders on hand which I put in its place. But I am baffled by the skinny lead wire that is fused at 35 amps??? I could only find 30A mini fuses at my local auto parts store, so that’s what I put in. So, I have 2 questions:
1. How can the circuit get by with such a skinny wire but carry a 35 amp fuse?
2. Do you think I’m OK with a 30 amp fuse instead of a 35 amp fuse?
Hopefully those of you with more experience can enlighten me. Thanks!
