What does a voltage regulator do on a dirt bike?
Voltage Regulators The Voltage Regulator is an important component of the electrical charging system, and keeps your motorcycle battery from being overcharged and damaged.
What causes a motorcycle regulator to go bad?
One of the primary causes of failure is heat. Different motorcycle manufacturers install the regulator rectifier in different locations of the bike, with some placing the part near the radiator or other sections of the bike that impede airflow. Depending on where your bike’s regulator rectifier is located, the part can overheat.
What causes a dirt bike to not start?
Spark – This is usually the first thing that everyone suspects when a dirt bike won’t start, but this can also be misleading because a plug will frequently fire out of the cylinder, but under the pressure of being in a cylinder, a spark plug will frequently fail to fire and light the air / fuel mixture.
Why are my crank seals leaking on my dirt bike?
Crank seals in two strokes can wear and start to leak, creating problems. If a crank seal is leaking it can allow gearbox oil to enter the crankcase and causes the bike to run rich. A typical sign of this is an oiled plug or oil dripping from the exhaust pipe.
How does a bike regulator rectifier work?
Some bikes have single-phase designs because they cost less to manufacture, in which case there would be two wires rather than three. In any case, the regulator rectifier converts the AC power into DC power, then regulates the DC power to ensure that the power doesn’t go over around 14.5 volts.

Where is the regulator located on a motorcycle?
In most motorcycles, the regulator and rectifier are located together in the same unit, but other older models have them installed separately. Here’s what you need to do to test your rectifier for failure:
