Good morning all - recently purchased a Series 3 which has had a Perkins Prima fitted with some lovely wiring behind the dash! Never having owned a Series 3 before, I find that the indicators and all other circuits are 'live' even with the ignition key removed (column mounted switch) - Should they be? The main fusebox, in the column cowling is powered by a constant 12v, is that correct? - Any help gratefully received, thank you
 
THE WHITE CABLES ARE IGNITION ON FEEDSSO SHOULD NOT BE ACTIVE WITH KEY REMOVED

Thank you all - Especially mystery, for that diagram. That will definitely help, far better than the one's I've found so far. Cheers
 
If its had wiring mods its hard to know. But many circuits on old cars did bypass the ignition sometimes for good reasons. The sidelights and headlights are often on the same fuse and it s legal requirement for sidelights to be available without the key (for parking at night) so the headlights can often be left on. Same with indicators, they are often wired on the same circuit as the hazards, because separating them is a pain, so the indicators are often live all the time. I would leave it alone for a while, drive it, then decide what you want on and what not, then work out how many extra fuses and relays it will take (quite a few). I did do this on mine but it takes some working out.

Thank you - That may well be what I end up doing
