Fbh number.

lathbury · 14th November 2013, 13:48

I have a cdt 02 75 with a fbh problem, I need to know which model I have so I can either add 12v or short the relevant pins. I don't see either of the two numbers I am supposed to find, they are not on the Webasto label on the front. Anyone help please?. Thanks, John.

Hi John

The number is on the label at the front of the heater below what looks like a bar code. It is difficult to see with the heater inn place - easier if you loosen the fixing bolts and ease it up a little.

Many thanks Boater and FrenchMike, that is my job for the weekend. I don't understand the numbering of the pins, is it bottom left is number one and bottom right is number six?.

The last type has a white /red wire going to pin 2 (Kbus)

I have done as Boater suggested, lifted the fbh up amd written down the numbers, they are"9004621B and 98570C", which is the model number. I have a red/white wire in pin2, to test it do I remove the wire from the heater and put the test wire in the hole and does the ignition have to be on or off?.

Never mind ignition
