Sounds like there is a problem, but why use a flashlight to try to=20
confirm it? (I assume you know different, but just in case you have some=20
sophisticated flashlight with some clever control circuitry, or PWM etc)
Just to be sure, why not just use a battery + resistor to produce a=20
predictable current. Or a bench supply if available.
Test on a few ranges too.
As Bob said though, dodgy leads/sockets sound like a distinct possibility.
Is the voltage (or resistance) working okay? Have you tried the test=20
method suggested there? I think you would have far more chance of=20
success that way. IME, cheap multimeters can be terrible at measuring=20
current but *usually* not too bad with voltage.
