Thats why I thought it was fat matt taking the p!ss

There is a clear level of lacking on both basic industry and technical knowledge

Sorry but Its got bad news written all over it.  We all started somewhere, but wow

Well indeed. Ask these sort of questions fitting an alarm to your uncles garage, or playing around with an old panel in the shed,

not before you start an URNable job!

 

HOWEVER, lets not make the OP run off, saying we are a bunk of w**kers just yet; as that will only propagate the issue...

diode for visual confirmation Whistle??

What you mean visual? Or you talking about LED , 

 

As a house bashers I assume he's talking about when relays lock up without a diode

 

But your asking for visual, that would be a light emitting diode , unless your thinking it can be used in the same way
