I think this is true with all trades
I got sent out to work with an apprentice on a job him and a journeyman (20+ years in the trade) had been working 2 days on. A lot of changed parts and phone calls. We fixed it in 15 mins with 0 parts needed. Someone was pulling on wires and must have pulled on off a relay and got it out back on the connection next to where it needed to be. The apprentice was in awe that it was that simple and fast. I told him it?s koting special I looked at the diagram and tested for power from one connection to the next and when I got to where it dropped, bingo no wire there but the wire I needed was on an under contact. Moral of the story start at step 1 and go though step by step. There is no level of experience that outweighs proper trouble shooting procedures. (Also is the first 5 of the same part don?t fix it, the next 5 won?t either)
Good look sounds like it went good
