Advice for all you car people!

I do see people just shuffle others off to Read the FSM as if it is the answer to everything.
Sometimes the pictures in there do help. Sometimes though the FSM was printed at a point long before a flaw was found, a replacement superseded it or a modern fix had been found.
In some cases, the text of the FSM is a bit abbreviated and hard to follow.
Mine for a '70 Charger/Coronet has several wiring diagrams that don't show some of the wires my own car has and my interior harness was 100% original before I got the car. The FSM is great but in many cases, real life experiences can explain how to fix something in a way that is much easier to understand.
