It’s been my experience that the majority of problems........(And by that I mean things that go bump in the night)......can be solved by coming to this site and:
1. describing what the events or conditions were that led up to the problem
2. remembering unrelated events that may have been a contributing factor

....and usually within a day or, the back and forth chit chat and ridicule from these experienced folk will give you a to do list that will save you money and/or time. Even if you can’t turn a wrench you will be able to go to a garage and look them in the eye and describe the solution..... and scare them with your troubleshooting skills. Don’t go in like an unmarried school marm for they will ravish your pockets.

quite a number of their solutions will be following their directions and simply doing some fairly uncomplicated stuff........the exceptions to the untrained are multimeters, reading
schematics, and learning what screem means.

when you were younger learning clefs, metronomes, and taking piano Lessons ....these guys were under a car in the driveway.
