Dam Webasto again

[pcatterall]

Have returned to trying to get my inherited Webasto working again.
Discover that it is an ST model ( Airtop 2000 ST) it is certainly different than the model I had before. That model had the two leads for the pump coming out of the air inlet and they were black. This one has all the wires going in and out of one 9 way block I guess that the red and brown are normal battery and that the single black is the switch on lead ( as per the old AT 2000, but which leads power the pump baffles me. Judjing by wire section alone it may be the orange and green leads. Has anyone got this model by chance?? If so very grateful for any info.
Regards Peter

Thanks for trying Rob, you got me all excited!! but, alas, that is for the AT2000 The AT2000ST is quite differently wired.
I'm always getting heaters to mess around with and one drawback with webasto seems to be the way they swap and change things which could remain standard. With Eberspachers they seem to stick to their coding so that you know what is what.
Thanks again.

Thanks Cliff, I'm a bit embarrased after your efforts to say 'I've seen that one as well'!! This model looks much more like the one I have but my 2000ST is quite different inside, The 2000S has a mother board with all the componants visible, the ST mother board has them all contained in a capsule thing.
Many thanks, who is going to get the free beer now??
