I have a 15 Yamaha MT-125. I am getting fault code 19 and she will not crank over. I tried checking the side stand sensor for voltage. She still won't start. Help?

I think error 19 can also be caused by faulty wires going into the ignition switch. Look for anything chafed or corroded around there.

There's probably a couple different possibilities. One could be a bad battery, regulator, stator, loose wiring connections. Do you have a multimeter? If so you can measure the output of the battery when trying to start the bike. If it's under 9 volts you might need a new battery.

Does the bike try to crank over? Or is there no noise to the ignition switch?
