RR Classic EAS Timer Relay Issues
This is a re-hash of an old topic for which I can't find any recent posts/replies on this forum. Accordingly, I decided to post a new thread.
I've been suffering with intermittent malfunction of the EAS timer relay on my 1993 RR Vogue Plus for several years now and had some success with the substitute 4-pin standard relay approach suggested by many "victims" on various international forums . The problem with that is the 5th pin on the original AMR 1111 communicates with the EAS ECU (and other parts of the system) and without that, as soon as the system experiences anything unusual it goes into fault mode and won't clear until I refit the original AMR 1111 and use EASunlock to reset the system.
I did mess around with my original AMR 1111 (after obtaining a second-hand working one to keep my RR functioning), and discovered the problem is that the miniature PCB relay(V23072) doesn't like lying on its side, which is the orientation in the AMR 1111 designed mounting position. This because the relay armature wears over thousands of cycles and can stick. The AMR 1111 assembly sits with the pins facing downwards but the PCB is fitted into the enclosure vertically with the miniature relay sitting with the pins to the side. If I remove the assembly and its mounting socket from its mounting tab and lie it on its side the fault doesn't occur.
I've removed the V23072 relay from the PCB and replaced it with a new one I obtained from AliExpress. Bingo!
