I have a starclass 695 and have been told that Knaus do not wire up the fridge on 12v as the current pull is too high for the car to cope with so fridge warms up on a journey. Has anyone else come across this cheers

Isn't there a wiring diagram in your manual, the majority of other vans do not have a problem but then again German car manufacturers are well known for exporting vehicles not wired correctly to international standards.

I don't know what you mean by not wired correctly to international standards. The standards only state which applications are assigned to which pin, but they don't require all pins to actually be connected.

Thats a new onesurprised

The problem is /was that most modern cars fitted with "smart?" Alternators need to be kept under load to supply power for any thing other than what is fitted to the car

ie the fridge on caravans, 

I would do as suggested and check your c/van wiring diagramme to check that 

A decent tow bar fitting company can sort itwink

Have you connected the car and checked to see if the fridge operates on 12v?

One can only assume that they dont wire their motorcaravans to run on 12 volt whilst on the road!!!!The electrical connections would be through a relay and thereby not be a huge load!!!wink

Commercial vehicles alternators are normally capable of much higher output than a car, as they are very often asked to do a lot more than a car, and the length. of cable would be much shorter than to a caravan combination surprised

Really. My Hobby has everything working when connected to a factory fitted towbar on the Mercedes.

You are of course correct, I was generalising and should have said "some German car manufacturers".

The vast majority of car alternators will easily cope with the relatively low power demand of an LV absorption fridge running on 12v therefore the cabling does not need to be extra large.  Of course it would help if the OP was to give the fridge model number and car details.

ISO standards exist to ensure quote "products, processes and services are suitable for their purpose". how can it be suitable for purpose if it is not connected.
