Replacing the Fuse
Your HTX-242 (and vehicle) are protected by a 15-amp fuse in the
HTX-242’s positive (red) power wire. If the HTX-242 does not turn
on, even when you are sure the power wire is properly connected to
a 12V DC power source, check the fuse and replace it, if necessary.
1. Snap open the in-line fuse holder.
2. Remove the fuse from the holder, and slide the fuse out of
the end connectors.
3. If the fuse’s filament is no longer intact, replace the fuse with
a 15-amp 1
1 / 4
× 1 / 4 -inch fuse (Cat. No. 270-1073).
4. Replace the fuse in the holder and snap it closed.
Caution: Use only a fuse of the recommended size and type. Using
another type fuse, or defeating the fuse protection, could damage your
vehicle or your HTX-242. If the fuse frequently blows, there is a problem
with the HTX-242 or its wiring. Have that problem fixed as soon as possi-
ble.
