My congratulations Mike on solving a long term mystery!
Now to the practicalities for us who have no idea what elec components are or do..
I realize that quite apart from the actual FBH there are other items = fuel pump, a fan blower of some sort, elec feed to some sort of glow plug, exhaust system, etc etc that may now fail to work due to lack of use over the years..
I don't mind paying, and am willing to travel to get my FBH working, but it may need more than just repairing the circuit board.. So is anyone planning on making a comprehensive repair service available in the UK for those of us who need it please??
