Review: Fundamental Electrical Troubleshooting by Dan Sullivan
The book centers on the idea that 80% of all electrical faults are located within the circuit rather than the components themselves. By assuming the fault is in the circuit, technicians can significantly improve their diagnostic "batting average".
- Not for Engineers: If you are designing power distribution grids or calculating load calculations for a new facility, this is not the book. It is strictly for troubleshooting.
- Basic Electronics: While it covers control circuits well, it does not dive deep into PCB-level component repair (like soldering microprocessors). It focuses on field-replaceable units and industrial controls.
