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.

Four steps, in this order, every time
Diagnosis-first is the whole method: measure, write it down, then price it. It is also why every job, gas filling included, is quoted in writing after the checkup.
We test before we quote
The free 30-point A/C and electrical checkup runs first, about 15 minutes, with a written report of what was measured.
You get the estimate in writing
The report says what was found. Gas filling, like everything else, is quoted in writing after the checkup, and nothing starts until you approve it.
No work starts until you approve
Nothing is opened up or replaced before you say yes to the estimate. If the diagnosis changes the scope, you hear about it first.
Repaired, then checked again
The approved work is done and the car is checked again before handover.

My car starts all week and is flat on Monday.
That is a parasitic-draw pattern, what the car pulls with everything switched off. It is measured directly rather than inferred, alongside starter current draw.
How do you know it is the starter and not the battery?
Starter current draw is measured with an amp clamp. A starter pulling high current will flatten a perfectly healthy battery and get the battery blamed.
