12 Volt Fridge Wiring Diagram

As an example a large fridge that is rated at an average of 2 1a at 12v a small fridge used as a freezer rated at 1a at 12v double the rated current use when used as a freezer 2a instead of 1a an led light rated at 0 5a at 12v that operates for a couple of hours per day and an 240v ac television rated at 180w used for a couple of hours per day.

12 volt fridge wiring diagram. A wiring diagram is a simplified traditional pictorial depiction of an electrical circuit. Battery reads say 12 6 volts but the outlet is only receiving 10 6 volts. Basically the fridge will turn off when the battery reaches a set voltage. The car battery can run the fridge 12 volt system because your car alternator can put out the 10 amp current the fridge will draw.

Most of these outlets state 120 watts max but when i put just a 100 watt 8 amps load on them they immediately drop about 2 volts i e. On some models of dometic fridge the fridge can be either a 2 way or a 3 way model the fridge model number does not inform the installer which model it is at times as a rule of thumb if the last number is a 3 in the model number it is a 3 way fridge. Upgrade your wiring to handle the demand. Since the van has it s own battery i would suggest you run the fridge from that and use the anderson connection from the tug to charge the van s battery whilst your driving.

The wiring is simply not heavy enough to supply a reasonable current at the required voltage and this is crucial. For more information spare parts or repairs. It reveals the components of the circuit as simplified shapes and also the power and signal connections in between the tools. The caravan battery cannot run the fridge itself only the light and igniter because 10 amps current would flatten even a big caravan battery overnight.

Most 12 volt camping fridges these days have a low battery cut out feature. The main issue that we find with your cars 12volt battery running the fridge is voltage drop. This happens when the guage and distance of the wiring from your cars main battery to the trailer plug is insufficient to handle the high current draw from the 3way fridge in your camper. I would suggest that you isolate the internal wiring from the fridge from the rest of the van s wiring to ensure it can t use the 12 pin supply.
