6.TROUBLE SHOOTING
● Your fridge has built in battery protection and needs a
minimum 10.9 V to start and 9.6 V to continue operating.
● During operation a load is placed on the power supply
and voltage can drop by as much as 2 V, especially if
the wiring in insufficient (less than 6mm direct to battery)
or if there is a loose connection somewhere.
● If this occurs when you try and start your SetPower and
the power supply drops under 10.9 V it will not start. If
this occurs when your SetPower is running and the
power supply drops below 9.6 V it will stop.
6.1 POWER CUTTING IN/OUT
11
Wiring
● Often the standard wiring from the car battery to the
12V outlet is too small.
● A minimum 6mm automotive wiring should be used and
the earth should be wired directly back to the battery.
6.2 COMMON 12V POWER SUPPLY ISSUES
Battery
● The car battery could be old, undersized or have a
dead cell causing too much voltage drop.
