@Neve: Locate the resistor on the PCB in the battery pack. Place the two meter tips at its two ends and measure the voltage (!). Should be something around 6 V. Divide this voltage by 0,365 to get the charging current in mA.

Alternate method: open one of the two connections between the NiMH cell pack and the PCB (leave the other one connected). Set the meter to DC Amps and place its two tips at the two ends of opened connection, i.e. these two points are now connected by the meter. Now you can measure the charging current directly.

Dieter, I would if I could. But I partially sealed back the pack after rebuilding it. I don’t really feel like reopening in again unless I really have to.

But thank you for the idea.
