Fault diagnosis - treasure hunt?

I am starting to post a series of fault-diagnosis photos on the OntarioACHI message board.

These are aimed at the newer Inspectors in Ontario and will have a period for answers, which I will not comment on, with a follow-up post sometime later with more clues to the original problem and the resolution I took.

The first one is here

I like Len, what a great idea!:smiley:

Here’s a new one for you. This will be another multi-part thread to assist new Inspectors in thinking outside the box, but inside the SoP to ensure they don’t miss anything.

It’s on the OntarioACHI site here
