Fuse verification and replacement
6. Skip this steps if you are not verifying the power entry module fuses.
a. Use a flat blade screwdriver to open the fuse compartment cover and remove
the two fuses.
b. Use an ohmmeter to verify the fuse continuity. The resistance should be short
circuit, close to zero ohms. Replace any fuse that measures significantly high
or an open circuit (infinite resistance). Only replace with 2.5 A slow blow rated
fuses.
Fuse spec: 2,5 A slow blow fuse
