Re: Dead bike
i'm not trying to be pedantic i'm trying to let readers understand how DC vehicle wiring works. its a common misconception by a large majority of the public that a "ground/earth" on a vehicle has no power so is never tested. if people replace the word ground/earth with common they might remember that its also live. most people when testing vehicle wiring with a DMM/CT only test the "live" wire from end to end but completely forget to test the "common". they also use either the frame or battery negative as the return (common) when testing a "live" wire, this in turn completely misses out an important part of testing.
once you understand that there is no earth/ground and start thinking return/common then you will find DC vehicle wiring much easier to work with. every single wire is either on or off regarding power and that includes the common.
a common is a convenient point/collection of wires in which to return power to the negative battery terminal and most of your vehicle electrical circuits use them especially true of lighting circuits.
