For the part of you with thirty open tabs that never became anything.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Quick Wins and Power Rescues and Finding the Invisible Break. It starts from scratch.

Key ideas in Car Electrical Basics
- The donor battery only provides enough power to crank the starter motor
- Positive terminals are connected first to minimize short-circuit risks
- The car must be driven for 20-30 minutes to allow the internal charging system to work
- The dead battery is the primary source of dangerous hydrogen gas
- Turning the engine off immediately will likely result in another dead start
- Connecting the final ground to a metal engine part keeps sparks away from explosive battery fumes
- Understanding that a jump-start is only a temporary fix to start the engine
- The safe sequence for connecting cables to avoid sparks near the battery
- Corrosion creates high resistance that prevents the starter from getting power
- The battery's main job is just to start the engine
- Cleaning the terminals can often 'fix' a car that won't start without needing a new battery
- The alternator generates electricity to run the lights and radio while the engine spins
- Metal-to-metal contact is required for the high amperage needed to start an engine
- Most lead-acid car batteries have a reliable lifespan of 3 to 5 years
- Identifying corrosion as a physical barrier to electrical flow
- Batteries often fail without warning once they reach their age limit
