- 01Battery testing from start to finishCustomer says: “It just clicks in the morning.” Is the battery actually bad, or are we about to replace the wrong part?Free preview35 min
- 02Voltage on a real vehicleA component has 12 V at its connector but still does absolutely nothing. How can 12 V be there and the circuit still be faulty?Members only35 min
- 03Grounds and bad earthsStarter turns slowly, lights behave strangely, multiple systems complain — yet every positive feed looks good.Members only35 min
- 04Voltage-drop testing properlyThe cable looks perfect and continuity says it is good, but the starter still cranks slowly.Members only35 min
- 05Multimeter use without blowing it upYou move the lead into the amps socket, forget about it, then try to test battery voltage. What actually happens?Members only35 min
- 06Current and amperageWhy can a tiny sensor use milliamps while a starter motor can pull 200–400+ amps from the same 12 V battery?Members only35 min
