So last night car is dead as a proverbial. This am I remove the middle relay (top and middle are the same) to get a part number. Wander in to garage an hour later and think i'll just turn the key and hey presto car starts so ignition relay must be the top one then, but middle relay is still out by my PC so indicators not working. Put middle relay back in and evrything is working. Problem is i'm now unsure of taking the car out as I do not want to breakdown again. I think the answer id to get a voltmeter diagnostic done on the fusebox/relay ignition system by someone who knows what they are doing.
