My 1980 GS1000G has been starting pretty easily for the past month or so. I even went away for a week and it sat with no float charger, and it started with little hesitation then when i returned. Then the next morning it wouldn't turn over. It seemed like a dead battery (relay clicks, motor tries and bogs, lights dim) which made no sense considering the battery is only about a month old. I tried to jump it from a deep cycle marine battery i've used for this before on several occasions, it still wouldn't turn over and the motor-side terminal on the starter relay started to smoke. So i temporarily gave up, put it all away and went late to work. When i got home i found that the bike battery reads around 12.5v with the key off, and stays there with the key on, but drops to around 5 or 6v when i hit the starter button. I tried jumping it again from the big battery, which did get it to turn over and eventually start, but it made that terminal smoke again (insulation was melting near it), and also the battery ground and positive wires got hot too.
To me, this says the starter motor is drawing too much current. It doesn't smoke when i use just the bike battery because that can't supply enough current to heat up, while obviously the big battery does. Does this seem like a reasonable explanation? This would seem like i need a new one right? Or at least a rebuild
