How do i measure current being drawn from my new car stereo amplifier, using my bog standard digital auto-ranging multimeter? I expect it to be about 30-50 amps, and naturally didn't want to connect the multimeter's puny wires across this (since an ammeter has to be connected in series)
Also, to measure voltage across, say, a lampholder terminals, do i just turn the empty lamp on and probe the 2 terminals with range on AC volts? It just doesn't feel right!
