Ian. OK, as you say, there loss. If you are free tomorrow I would like to take you up on your offer to look at your wiring. I'm technically still on call this weekend so I'll call you Sunday, after a suitable lie in of course! For all of you still following the ins and outs of my electrical problems I would now say that the 'wiper control board' on the electrical diagram may be at the route of several weird DMC problems. The board *seems* to act as the ground for the obviously connected indicators, wipers and seatbelt/door warning buzzer. Not so obviousis the fact that wobbling this board also causes the gauges to move and the air con and fans to cut out. I am not sure why this should be, but with the board suspended all my gauges ZERO CORRECTLY. The revcounter, and temp gauge all go to zero and stay there. More info when I get chance to compare to Ian's unmodified car! John Chapelhow DOC 19 : 'Boeing' 0737
