Can anyone recommend a good step-by-step fault finding book or guide?

I'd like a decent book (or even online guide if possible) that has a good step-by-step approach to fault finding. Does anyone know of one? Similar to the Part P Doctor book by Alan Lynch would be great. Many thanks in advance.

Thanks very much for that. Does it list such things as fault finding for tripping RCDs? I think I'm OK with things like Polarity faults, Open circuits and short circuits.

with RCDs tripping faults, i think that you will find more info by reading threads on this forum than in any book. LOL. basically, it's like any other type of fault finding. narrow it down again and again until the fault is traced.

That's what I've been doing, with regards to reading. So, does it cover this issue though? Thanks again.

with RCD tripping, you 1st need to trace it to 1 circuit. then split circuit , e.g. if a RFC, open ring at approx. mid point, find out which leg gives the low IR reading, then split that leg, and so on, till you trap the fault at or between 2 sockets.

Thanks very much, I think that all makes sense. This kind of knowledge is invaluable in the real world, as opposed to anything learnt in a college classroom.

Just brought wiring systems & fault finding by Brian Scaddan from amazon,good read.

Wherever you start it's sods law that it will be the last one you come across! Agree though you narrow it down by getting the midway point.

With tripping RCD's I always ask the customer what they were doing when it happened - more often than not this gives me a clue where to start.

there is no such thing as a book on fault finding, they are a catalogue of another persons experience, fault finding is a skill linked to a logical mind, logic, like Murdoch mentioned above^^, "what were you doing when the fault occurred?", clue one, "what circuit is that on?" "what controls that circuit?", "if the control for that circuit was defective, what other symptons would i see??"" etc etc,
ask yourself these questions as you approach a situation, if its test readings you are assessing and you truly understand them, the process is exactly the same.:17:

There is no how to book for fault finding, I often thought of making my millions by writing a book purely on fault finding untill I realised it would be a very short book as the techniques used are pretty similar for all fault types, so learn the few methods used and apply them to whichever fault your trying to locate.

On RCD tripping 99 out of a hundred will be somthing pluged in or switched on! DONT trust the customer when they say everythings unpluged!! and rember switching off the socket normally only breaks the live which isnt good enougth so it needs unpluging.
As for books I think hands on is the best way to learn, but that can take years
