But of course even if the connections were OK the resistance measurement would be above 75R due to the other components. I think ( but may be wrong ) this would need to be done with a digital meter and probably with the unit powered down to avoid the possibility of damaging the circuitry?
You cannot connect an 'ohm meter' of any sort to live circuitry. You can only measure current, voltage and frequency.
