What are the different types of voltage regulators?

Basically, there are two types of Voltage regulators: Linear voltage regulator and Switching voltage regulator. There are two types of Linear voltage regulators: Series and Shunt. There are three types of Switching voltage regulators: Step up, Step down, and Inverter voltage regulators.

How does a reverse breakdown voltage regulator work?

Electronic voltage regulators have an astable voltage reference source that is provided by the Zener diode, which is also known as reverse breakdown voltage operating diode. It maintains a constant DC output voltage. The AC ripple voltage is blocked, but the filter cannot be blocked.

Why are switching regulators more efficient than linear regulators?

Switching regulators are efficient because the series element is either fully conducting or switched off because it dissipates almost no power. Switching regulators are able to generate output voltages that are higher than the input voltage or of opposite polarity, unlike linear regulators.

When did I have to replace my battery in my Road King?

I recently had to replace my battery in my 2002 Screaming Eagle Road King. Everything was fine after the R&R. I managed to get one ride in before having to store the bike for approximately 2 months.

Why is the regulator on my Harley stator not working?

The regulator protects the battery voltage and when the battery voltage climbs too high it shuts off current to ground and bleeds it off as heat. That is what the heat fins on the regulator box are for, to dissipate the heat. If the regulator did not monitor the voltage to your battery it would destroy it.

What should the charging voltage be on a Harley stator?

You can use 13 as a good all around battery voltage. That is a good healthy battery staying charged just above 12 volts. Example only: Let’s say the stator is rated for 10 amps x 13-volt battery: 10 x 13=130 watt charging system. So you have a 130-watt charging system in this example.
