Fuses
IMPORTANT: Always carry spare 5 and 20 amp fuses.

correct the cause of the overload. If the cause is not found, the fuse may open again.
1. Open the fuse holder and look at the silver colored band inside the fuse. If the band is broken, replace the fuse.
2. Replace the fuse with a new fuse with the same rating.
