Set meter to 10a and move the lead
Disconnect one side of the power to the LED module
Put meter in series ie. The disconnected wire to black and the disconnected side of the LED module to red. Best to connect up unpowered and then power on.

this is not measuring in series. i was told to measure A in series = under strain.

Fixed intensity LED driver modules provide a constant current across a voltage range. Any flicker if this is the problem or the fear could only be caused by fault in regulation loop or electrolytic capacitors aging.

Variable intensity LED driver of low profile design often uses voltage PWM and thus it often shows flicker, even faintly audible, although frequency is usually high enough to make it less noticeably than common 50/60/100/120Hz flicker.

i could dismantle this and hook up stronger capacitors. this is faulty by design.

Why not just buy a new driver from the many offerings? Here are a few:

I don't know what power consumption you need, but those ones are all 700mA output.
