8.2 Troubleshooting Guide
PROBLEM: NO 110/120-VAC POWER OUTPUT
POSSIBLE CAUSE
SUGGESTED SOLUTION
Inverter switch in OFF position. Turn inverter ON.
Poor contact with 12-VDC battery supply. Switch OFF the inverter; clean input
terminals, reconnect input terminals
and cable ends; reconnect cables.
Input power source below 10-VDC. Recharge or replace power
source batteries.
Total appliance current draw Reduce appliance load to 3000
watts maximum.
Inverter in thermal shutdown condition. Allow inverter to cool down; ensure
adequate air circulation around
unit; reduce current load to 3000
watts maximum.
DC fuse is open (blown) Ensure inverter is properly connected
to12 VDC power source with
correct polarity. Call Vector™
Customer Support. Remove
overload from inverter. If resetting
the front-panel mounted circuit
breaker(s) does not resolve the
problem, the inverter MUST be
returned to the manufacturer for
professional inspection of the internal
circuitry and internal fuses. DO
NOT ATTEMPT TO OPEN UNIT:
THIS WILL VOID THE WARRANTY.
Tripped circuit breakers on front panel Inspect circuit breakers.
of inverter Reset circuit breaker(s).
Excessive input voltage. Ensure that inverter is connected
to a 12 VDC to 15 VDC
power source.
Short circuit or neutral is grounded. Correct wiring. Inspect internal
circuit. Correct wiring.
