Scantronic 4600 door contacts not functioning

Do you need it, can it not be disabled, if your using the terminals? It's been ages since I seen one.

Repurposing a reed from something else maybe hit and miss they are fragile.

In your shoes Id buy a grade 1 surface contact and remove the reed from that

This is worth the try 

 

Providing you know how to solder and not butcher

I'd suggest it's past it. But if you want to keep it I'd bridge the Reed and use the external connections only. But as its the oldest electronic thing in your house it must be time to upgrade or if your not fussed just decommission it

You ought to look into wireless polling etc not just assume a signal will make it. The rf environment is way different now than when that was considered good

Actually that might be better but you could also cut the reed up top and use the legs to solder to rather than messing the board up

 

Agreed about rf

If he's using the external terminals the jumper on pcb bridges the reed ?

[datadiffusion]

Exactly if it's the on board reed, just wire externally and jumper the on-board.

 

(I mean honestly I'd bin the lot as discussed ad-infinitum but that is at least a no-solder solution)

Changed the reed switch. All works fine now. Good for another 20 years

Thank you so much to everyone that responded

you'll now be able to put you feet up & listen to your 8 track or maybe give your talbot solara another coat of autoglym...
