[QUOTE="Meroo, post: 296621, member: 8832"] Lol I have no need to I've done it a million times. No pms you don't need a load connected to a circuit to measure voltage drop plain and simple. get a battery and it's 13v. Get 8m of cable hook up the positive and negative measure at the other end of the cable with a voltmeter you may have say 12.6v. the loss is the resistance of the cable only very miniscule .Basically what your saying is you can't measure voltage off a battery terminal cas it's not connected to a load.. absolute bollocks. So when you have cables connected and measure the voltage at the other end of the cables it's exactly the same thing only you will register a slightly lower reading as you are getting a resistance loss over the cables and that is your voltage drop. :D [/QUOTE]
