Hi Everyone, my (refurbished) Webasto thermo top C seems to have a problem. It usually doesn’t start tho I have had it running a few times and it’s great but has never worked twice in a row. Lately it has refused to start altogether because the fuel pump isn’t clicking . I bared the fuel pump positive lead to test it and it works fine. If I tap it against the positive battery terminal i can see the fuel moving through the (temporary) transparent fuel pipe and even get the unit to fire up whilst doing this but when I stop, the fuel stops and of course it shuts down. . Have checked the continuity between both ends of the pump wiring harness and its fine but there’s no voltage pulse from the unit to the pump. The batteries are good and voltage is 14v when the sun is out.
Have tried all the restart/ on,off /5 seconds/ fuse out bollox and now i’m all out of ideas and considering abandoning it and putting it down to ( a bad ) experience.
Shame coz this is the time of year when we could do with using it because it’s cold in the mornings but not cold enough to put the Rayburn on…and it’s cost me about £800 up to now..Argh !!
Can any clever person think of anything I’ve not checked ?
Cheers
