True, & btw Eddie, I noticed you mention wanting those wires to be longer, but I can corroborate what they told you about altering them, I've heard from a number of guys who either shortened test leads, or replaced them with longer ones, & each & every time it DID affect the test results one way or another(though this is mostly referring to guys using the Robi, but I suspect it's also applicable to most ALL dynos). I really wonder if there's a way tomeasure thetotal resistance of the whole works & possibly usethe wire lengths to fine-tune a number of dynos to read much more closely to each other(though I only have my Robi, so I don't have any way of testing the idea)...oh, & I also agree about testing voltage, that's one of the reasons I chose the Robi, because it can be set to test a motor at ANY voltage I'm likely to use in a car(including 4 cell racing)....
