Current = Voltage across R245 divided by 6.2   :thumb-up:  We know that's what you mean't MJMP    :banana:

Check R245 is actually 6.2 Ohms as well - from the battery clip +ve to D42 anode (end without the black band) with power off and battery removed.

Edit:
Also check the battery clip resistance -ve to GND on the PCB is less than 1 Ohm.
