Core Diagnostic
Turn vague electrical fear into a structured test-first approach built around voltage, current, resistance, and wiring logic.
Use the DVOM like a diagnostic tool, not a decoration.
Refresh the electrical basics that matter in the bay.
Avoid false readings and bad assumptions.
Capture intermittent faults with the tools already in the drawer.
Learn where voltage-drop and loaded-circuit testing beat resistance checks every time.
Find bad connections under load instead of chasing ghosts.
Isolate weak grounds and shared-ground issues quickly.
Work battery-drain complaints without wrecking modules or losing the draw.
Read the map, choose the right checkpoints, and know when you have enough proof.
Turn wiring diagrams into a simple test path.
Separate input, output, and command problems cleanly.
Apply the full electrical workflow to a real shop-style problem.
