I have a 1989 T25 which I've owned for less than a year. I've noticed that when I'm driving I can lose the function of my temperature and fuel gauge (usually temporarily). Funnily enough it has happened when I put the window wipers on! The van has just be serviced and is tickety-boo in most other respects but my garage tell me the costs could mount if they have to do a lot of electrical tests. Has anyone else encountered this?

Think its a case of checking connections in the dash pod and cleaning all the earth connections on the crowns
