[QUOTE="helotaxi, post: 1777394, member: 550915"] 5 ohms? Are you crazy? 5 ohms would mean a drop of 5 volts with only a 1 amp draw. Basically if you can measure the ground path resistance in ohms with a basic DMM, it's WAY too high. The only way you should be able to measure it with normal equipment is indirectly with a clamp meter measuring the current and a voltmeter measuring the voltage drop from the amp to the battery neg post and then calculating the resistance.
