Do you need an alternator on a motorcycle?

The simple answer to this question is yes—however very few automotive style external all-in-one alternators exist on motorcycles. Rather, a stator and rectifier/regulator handles the power generation task. What Is A Motorcycle Stator, and What Does a Stator Do on a Motorcycle?

What causes the alternator to run full blast with no rest?

If something caused the alternator to run full blast with no rest, the unit could be fried. One possible situation that could cause this would be a battery with a shorted cell. The voltage regulator stops the alternator output when the charging voltage exceeds about 14V.

When does the alternator shut down the battery?

The voltage regulator stops the alternator output when the charging voltage exceeds about 14V. If a cell is shorted, then the voltage regulator will never shut down the alt, which could fry itself, and boil out the battery.

What happens if you replace your alternator 3 times?

Replaced twice that would mean a total of 3 bad alternators, that is a serious problem. Lets assume your able to start the engine, which means your starter is good, your probably firing on all cylinders, which means good ignition coils, and a good battery.

Why do motorcycles use stators instead of alternators?

That’s why a motorcycle uses the system of a stator instead of a whole regular alternator. There simply isn’t the room to fit a large part like that on a motorcycle. A magneto was more widely used on earlier motorcycles before the implementation of stators.

Why does my speedo on my Harley Davidson not work?

Also heavy oil buildup on your crank sensor will cause speedo problems. I have a 2001 Road King FLHR that I bought used. It died on the way home and then two more times. When I started searching the bike for the reason I found the battery connections loose, tightened them up and problem has gone away.

What causes an alternator to wear down over time?

Over time, there are several components in the alternator that naturally wear down. In my experience, it’s either the brushes (magnets) or the voltage regulator that break down the soonest. With the brushes, it’s not very complicated.

When is it time to replace your alternator?

Your alternator needs to know when each one of those things is plugged in and turned on, so that it can increase power. More importantly, just like with your breathing, your alternator needs to know when to put out less power.
