Measured with an amp clamp rather than judged by ear. A starter drawing high current flattens a healthy battery and gets the battery blamed for it.
Parasitic drawWhat the car pulls with everything switched off. This is the check for a car that starts fine all week and is flat on Monday morning.
Battery voltage recorded either wayResting and cranking voltage go on the report even when the starting complaint turns out to be elsewhere, because they are the baseline if the car comes back.
Fault codes read exactly as they appearOBD codes are recorded verbatim. A part is never replaced to find a fault, which is the fastest way to spend money without fixing anything.
