Notes to self, as no one seems to be paying any attention to these posts :-) auto box sensor locations: http://www.fordgalaxy.org.uk/ford/index.ph...amp;#entry84002 "Relay 30" as popularly known in these quarters is identified by Ford as R27. The relay is on all the time and runs hot, and as such it's MTBF is reduced a lot. To increase its MTBF it ought to be operated cooler, somehow, maybe add a ballast in series the coil or a heatsink, or maybe just replace the relay with a better one, rather than keep trying to 'restore the car back to its condition as it was designed' yes, its proof that "ford is designed to last" ok, last for a few years then conk out.
