Electrical troubleshooting is, for many of us, a challenge. I think it’s similar to a pilot who flies in VFR (Visual Flight Rules) conditions versus one who flies in IFR (Instrument Flight Rules) conditions. The VFR pilot relies on outside references to maintain control of his airplane; how the nose of the plane looks compared to the horizon, how the wing tip angles on either side align relative to the horizon, and the G-forces at play on his body. Sure, the instruments play a role just as they do when we drive a car, providing speed and other important information to further that control.
The IFR pilot, though, is dependent on those instruments and must actively ignore what his eyes and senses may be telling him. Often, there is no outside visual reference at all – nothing but sheer white caused by the enveloping clouds gathered around him. Imagine driving your car without outside visual clues!
