How to test my Big 3? + Big 3 Question

[Nevalite 10+ year member]

Hey,

I left some of the stock wires on while doing my big 3 but I figured it doesnt matter because the electricity will take the path of least resistance. The only thing I was wondering about was if it mattered if the new wires were above the old wires on the battery terminals, should I have the 0 AWG as the first ring terminals sitting on the battery terminals or does it not matter? Should I unhook the old wires altogether but leave them in place?

Also how could I test that my big 3 is working? I tested the resistance of my ground spots to my battery negative and it gives the same reading as when I touch the two ends of the DMM together (0.05 Ohms) So I know they are good, any other tests I could do to?

Thanks

You could check the voltage drop difference from at your under the hood battery and your amps.

I wouldn't sweat it. Just make sure the terminals are bolted down very well.

x2,

as long as they are tight and makeing good contact, then it's all gravy.
