DC power supply table
Intercepts the low voltage connector
In the following table you will find the colours and signals of the refrigerator connections of interest.
You can intercept the
You can act on the predisposition
Typically, the wire to be tapped is the violet-coloured wire which is located on Pin 1 of the predisposition connector.
Wiring
The section of interest is DC
In particular, we are going to act on the DC section and the “LOW CURRENT” part, everything else must remain the same
We intercept the purple cable
Cut power to the control section
Removing the positive to the control section (purple = +12V) will prevent the refrigerator from switching on.
Conceptually
Switch on remotely or manually
In a conventional installation, the violet has a voltage set at 12V.
When the power supply is first connected, the refrigerator switches on and automatically searches for the available source (Gas, 220V, +12V).
By having the +12V supplied by the CamperCheck the refrigerator will switch on remotely.
For manual switching, a switch can be provided locally.
Practically
Insert a relay to carry the load.
For correct installation the CamperCheck must drive a relay that will act as an ignition switch for the refrigerator, as shown in the block diagram.
Thetford n3000 series
It always lights up in the car
In the case of Thetford refrigerators of the n3000 and n4000 series, they will always switch on in auto mode as soon as +12V is supplied to the purple wire.
