I try not to appear too contrary, but for those not too expert, and using faithful analogue meters, if there is any live volts anywhere, measurement of ohms is best avoided as sooner or later volts will be encountered and wreck the meter.
Ohms Law is ohms = volts/amps and the approx amps can often be deduced from the ammeter reading.
(Analogue meters have the advantage that show erratic connections better, less affected by igniton, dynamo hash, other static like voltages etc, The very cheapest good enough for old auto work,except for setting voltage regulators or otherwise checking precise battery voltages.)
