Before installing the power cable, be sure to remove the
negative lead from the battery for safety.
After installation and wiring, be sure to double check for
correct installation before reconnecting the negative lead
to the battery terminal.

has not been damaged by short-circuiting, etc.
Then replace with a new fuse of the same rating.

heat resistant tape to protect against heat and moisture.
