Fault Code Guide

9. Use a suitable crimping tool and the crimp splice
from the repair kit to crimp the wires together.
9.1 Insert one of the stripped wire ends into
the crimp splice until it touches the wire
stop in the center of the crimp splice.
9.2 Center the crimping tool between the wire
stop and the end of the crimp splice over
the wire.
9.3 Crimp the splice on the wire.
9.4 Check the crimp to be sure that the wire is
held in place.
9.5 Repeat the previous substeps for the
other wire.
10. Place the solder sleeve over the crimp splice and
center the solder ring over the crimp splice. Then
apply 250°F (121°C) to the solder sleeve until
the solder flows into the crimp splice and the
plastic sleeve has shrunk against the wire and
crimp splice. Be sure to keep the heat source
well away from the heat shrink by sliding the
heat shrink at least 4 inches (102 mm) from the
splice joint.
11. Allow the solder sleeve to cool for a few minutes.
12. Place the heat shrink over the splice and center
it as best you can. Then apply 250°F (121°C) to
the heat shrink until it has shrunk completely
over the wire insulation. Some of the sealant ma-
terial should be bubbling out of the ends of the
heat shrink.
13. When routing additional electrical wiring, make
sure all circuits are properly protected and se-
cured.
14. Connect the batteries or turn the battery discon-
nect switch to the on position.
15. Verify the operation of the electrical feature(s)
connected to the optional switch output.
16. Remove the chocks from the tires.
