i'm trying to find out what each relay does in my 405 . i'm having a problem with the permenant live circuit ,the alarm stopped working the cetral locking and the interior light . i bought the car stolen recoverd and some of the fuses were missing so i replaced them . when i put the fuse in the perminant live (fuse 15 ) i heard a relay go and all worked but as i was using the central locking to work the alarm all stopped and hasnt worked since so i'm hoping its this relay i heard as i cant find anything else wrong .....anyone out there have any ideas......thanks shane
