We had a student with a long-term problem of dash lights that quit working on their Suzuki. I demonstrate how to use the Power Probe to diagnose this within minutes.
Do you struggle with electrical diagnosis? Wanting to be a rock-star with electrical? Let me train you!
Here is a solid flow chart for fast accurate diagnosis. Tip 1-4 HAS to be is good integrity ALWAYS. As I worked on my personal craftsmanship when performing electrical repairs, I've found that it's just good practice to "maintain" these items 1-4 regardless. I previously would work backwards on this list to diagnose problems the fastest. 
I found that building steps 1-4 into muscle memory not only made me consistent when troubleshooting electrical problems, but improved the quality of my work. 
Here is my list. Repair or maintenance as you go. Think: clean connections and dielectric grease connections!
Electrical diagnosis Checklist:
1. Battery testing (load tested!)
2. Ground Verification 
3. Locate Wire Diagram (This is a real time saver)
4. Fuse Inspection
5. Test for Power to component connector (vehicle side of harness)
6. Test for component Ground
7. Isolate component from vehicle and bench test with the Power Probe.
