Hmm a bit of a difficult one to answer that.
Well the alternator times out at around an hour if that's the fault.
The draw test depends,
If and I stress if the current draw is there when being tested the all well and good,
But some cars have active modules like the alarm system that doesn't come alive for a certain time.
Best to say an auto spark will start by charging an hours labour to test the charging system and draw test it.
But like I stated if the current draw isn't apparent the time will roll on until it's found.
Electrics can be a pig,
10n hours to find a fault that take ten mins to fix kind of thing!!
But an hours labour is where it will start.
And fingers crossed it will be enough.
