Maintenance
For best DC-DC performance, periodically check the unit and related wiring monthly as well as
the installation location:
1.Inspect the wiring and note any wiring cracks, wear, tear, corrosion, or loose wiring and
replace immediately. Inspect wiring terminals and ensure they’re tight as they may become
loose during vehicle vibrations.
2.Check that the battery charger is free of dust, liquids, or heat sources and ensure the DC-DC
is receiving some ventilation. Improved ventilation improves performance.

1.Inspect your connections for tight, secure, and undamaged
wiring to and from the DC-DC
2.Check fuses for any breaks and replace them to continue
normal operation.
3.Use your multi-meter’s (check with manufacturer) continuity
test to individually check each line (positive and negative) at the
input and output to verify consistent connection. Audible
multi-meter Beeps indicate continuity. No sound indicates
connection break.
