Hi all
Can anyone tell me the correct way to test the Webasto unit.  i have read to apply power to pin 1. does that mean to remove the plug and just attach to pin one or do you tap into the supply wire and leave the rest of the wires connected.
Thanks

Just run a wire from the battery jump/ charging positive lug in the engine bayto pin one whilst the plug is still in. It should Run and get hot. You can here the pump working too. If you remove the expansion tank cover you should see a jet of water in there too

Thanks for that.
