how wierd fuse box

[Guest cortinamad-gonetoo]

how come for a good year (maybe a bit longer)

 

my central locking worked taking the live from the fuse box (which i tested and it was live with ign off)

 

so a few moths ago it started playing up and i couldnt get into my car

 

i just left it untill today i decided to investigate, the said live from the fuse box was live and central locking worked then just stopped working and upon testing the fuse box again its now not live without ign on

 

it seems intermitant that some times its live with out ign sometimes it needs ign on

 

looking in my cortina manual its the fuse for wiper motor,washer motor,reversing lights

 

so maybe it shouldnt be live until ign is on

 

(anybody know??)

 

but how come its live some times my central locking worked for at least a year wired up to this fuse?

 

plus the inline fuse to the central locking unit was playing up too so that wasnt helping matters

 

if it packs up his time im getting a new cetral locking unit as thats all it can be now, its wired to the fuse box at the cig lighter clock flashers etc so tht is live all the time

Dodgy fuse connection probably, try cleaning up the contacts

That's an ign live for those not constant but if you have water in the fuse box (which is unusuall) or the multiplugs under it (more likely) you can get all sorts of strange happenings,.

On me wifes escort diesel it wont turn off if it's been raining and the lights are on

well it must have had water under there for a bloody long time

 

its not till i looked in a haynes manual last night i realised maybe that shouldnt be perm live??

 

weird

No ign relay on a corty, all done by the ign switch and lots of wires solderd together
