Re: Erratic ignition now no power, no start
I wonder if some of the confusion is coming from this: Although simple electrical items like lights, heaters etc consume less current with a lower voltage across their terminals some more complicated items like induction motors do actually draw more amps to maintain their power output.

you've just said the same thing, It's effectively an additional load on the system. However it also creates a problem on both sides, the component being supplied the power in the first place will have a reduction in voltage. It's rated at 12v however Suzuki designed the system and the wiring to run at 13.8v curvy or 14.9 pointy IIRC. Im sure the OP said a starter motor was used alot; because the bike wouldn't start, it would start to overheat the circuit, it's not designed to be used like that, eventually the weak link would be found. In this case the connector. Was the connector actually found to be rusty? Or just melted? I can't remember or mustav skipped that page |

Although the corroded connector should probably be described as 'an extra resistance' rather than 'an extra load' - but I understand that you mean a load in the sense that work is being done at that point by the current flow, the unwanted resistance caused by corrosion of the contact faces will cause extra work (heat) at that point. Second law of thermodynamics basically says 'All energy ends up as heat' On every car I have owned I have fitted one of these braided leads between battery negative terminal and engine block, I do not trust all those small rusty connections between body and engine... https://www.halfords.com/webapp/wcs/...ch=earth+braid
