I have A Big Bike Parts LED volt meter. I always have had it wired direct off the battery. It has always worked great. I have a question. Does it matter where you wire it into? I mounted it on my leftside compartment lid and run the wire down under the compartment and wired it into the wires going to the power port that is in the compartment. It seems to work fine. I just want to besure I am getting a correct reading by wiring it in these wires.
