Thats how it works in A.C. but does it work that way in D.C. as well?

I don't particularry agree with the example of the starter. If the current draw increases as the voltage drops it is becasue the back EMF of the starter has decreased becasue it is turing slower.


For the purpose of wire gauge,it really doesn't matter why the line current increases,the point is that since the current increases,you need a larger cable to transmit that current without overheating.

Yes, I mentioned volts in the context of using it to determine the amperage of a load specified in watts.

What gauge did you use from the battery to the fuse block?

I went to Radio Shack and got their 30 amp fused wire and it comes with 10 gauge wire. I went from the battery to a relay and then to the fuse block. I also ran a wire from a bike fuse that is not energized until the ignition is turned on over to the relay coil and then from the relay coil to ground. Now nothing extra is on unless the bike is running, which means no more accidentally leaving the auxilliary lights on and killing the battery, or the Auto-Com and GPS and phone charger, etc.
