How does the solenoid work on a starter motor?
One, it helps close the circuit that moves current through the starter motor to cause it the start working. Two, the solenoid works a plunger that pushes the pinion drive to mesh the pinion gear with that on the flywheel. That transfers the energy of the spinning motor to the flywheel and causes the engine to start.
Can a weak solenoid cause a car to not start?
Although rare, a weak solenoid can allow the starter to spin without engaging the engine’s flywheel or flexplate. In such a scenario, you’ll hear the starter spinning, but the engine won’t crank. It’s possible for high resistance in the starter solenoid to cause the contacts to burn.
When does a solenoid need to be replaced?

How does the starter turn on a motorcycle?
The starter fits into the first gear, which drives a second gear, called the idler. That idler gear turns the clutch gear. That means the direction reverses twice, so the starter should turn counter-clockwise as you look at the output end, same as the engine.
Where are the starter gears on a Yamaha XS650?
This gear is linked to a gear that turns the gear you can justsee in the corner. The gear in the corner is on a shaft that runs to the other side of the engine. On the shaft on the right side is a small gear that engages a set of spring loaded gears that work like a bendix on a car starter.
Which is part of the starter engages the flywheel?
