What a helpful lot you are.
Going to check one myself today and good to have back up from you guys.

A good tone & trace kit can be your best friend with jobs like that, especially on bigger systems.

I went to a job in a flat the other week where the boss just gave me a 'bell 501' handset and said 'go change that over'.
Wasn't as easy at that! There was no logic to be used, looked at new schematics, no good. Tested old for microphone and power but no solid evidence of what would go where so being 12v dc max I got the daughter of the flat owner to go stand by the door, I phoned her on loudspeaker and tried every combination of the six wires until we got it. Thank you vodaphone, thank you daughter - yeh Thanks Boss!

Thanks for the update OP, glad you got it sorted.

What update DPG ?

 

[DPG]

The OP told us he'd found the fault.

 

[Rpa07]

Not the OP @DPG was a SP (secondary) - he might update us but he hasn't been yet! Confused. Com!

 

[DPG]

I see what's happened. The op did tell us the outcome but it was in May! I think someone has resurrected an old thread.
