A friend of mine is a mechanic, and long ago he told me if my motorcycle’s battery fails and I can’t get another vehicle to help me with jumper cables, what I have to do is have the ignition ready, get it into 4th gear, and after giving it some momentum to suddenly release the clutch.
How does this work, and why 4th gear specifically?
In: Engineering
So I’m not sure about bikes, but cars have alternators. Alterators, when you first start your car, your using power straight from the battery, but as soon as the car starts running, there’s a bunch of loops of copper and a magnet in the middle, inside your alternator. So, your engines on, the alternator is spinning the magnet which creates enough power to recharge the little bit of juice taken from the battery and run your lights, radio, etc. I can’t imagine why motorcycles wouldn’t have alternators. So what he’s saying is, put it in 4th gear, so that the alternator spins when you push it, let it spin fast enough and long enough and it will charge the battery just enough to start the bike. Let it sit a minute and run and the battery will charge up.
Hope this helps. My first big explanation on this page.
Tl:dr Car tires spin, magnets spins, electricity is generated, car go brrrrr
