Where is maxi fuse located on Harley Davidson motorcycle?

The Maxi Fuse is usually located at the first main wiring "intersection" or "branch" device (rubber/plastic) housing coming off the main RED (+) battery cable, usually alongside the battery. When you remove the cap/lanyard, the fuse measures 1 1/2" L by 1 1/4" W x 1/2" w/ color coded/labeled body and 2 blade contacts. You can look inside and see if the fuse link element is clean, intact and no parts of the fuse should show corrosion or open conductor...or use an ohmmeter to check fuse for continuity.
