If the charging port is OK check that the battery fuse is in
good condition. With the batteries disconnected remove
the fuse cap, inspect the fuse to see if the fuse is blown.
To make sure the fuse is not blown, set the meter to ohms
and measure the resistance across the fuse. See (figure
A1.4.2). If the meter reads more than one ohm, change the
fuse, or else proceed to the next step..
