well, yesterday....
Morrisons car park, started her up, starter kept running...
Bugger, turned her off, starter still turning over, so killed batt switch.
off comes the dash, pull the starter wire off the switch, nope still going, under bonnet, check wiring for shorts, nope...
ahh, relays, fuse box front off, pull the first yellow one, BINGO.. feck, now no ignition power AT ALL accessories yes, but no ignition...
after 3/4 of an hour trying to fault find, conceed defeat, and call RAC. uber fast response, he was there in 10 mins, as he pulls up I thinks, "ill check the ignitions switch"
Bleedin main power spade had come off, so as quick as he arrives, Mr RAC man goes, which is good as he admited "I aint gotta clue on these"
Still a knackered relay, but swapped it with one of the other yellow ones, and no problem now...
