Hi,

I have some problems with wiring the dc dc charger.

When wiring up like this i hear a ticking noise from the charger and i measure 12.8v on the output of the charger.

If i disconnect the + cable of the trailer battery the voltage is 14.4v on the output of the charger.

The charger shows a blue light.

All the cables are 35mm2 except the d+ cable

The connections and cables shoes are solid.
