You’ll note signs right away like poor starts, fluctuating meter readings, and dimmed headlights. around 13 volts, the bike will start to drain the battery. When this happens, it’s only a matter of time before the engine stops completely.
How do you test a motorcycle regulator?
How to Check a Voltage Regulator on a Motorcycle
- Set your multimeter to 20 volts DC (Direct Current) and connect the positive (+) and negative (-) leads to the corresponding battery terminals. …
- Start your motorcycle and rev the motor to 5000rpm, maintaining the engine speed during the testing.
- Using the multimeter, test the battery terminals again.
What are the symptoms of a bad voltage regulator?
Symptoms of a Bad or Failing Instrument Voltage Regulator
- Dim or flickering gauges. One of the first symptoms of an issue with the voltage regulator is dim or flickering gauges. …
- Inaccurate or erratic readings. Another symptom of an issue with the voltage regulator is inaccurate or erratic readings from the voltage regulator. …
- Inoperable instrument cluster.

What happens when regulator goes bad?
A bad voltage regulator can even affect your car’s engine. For example, as this car part stops working properly, you might notice your car’s engine sputters or stalls once in a while. It might also have trouble accelerating as you drive.
Will a motorcycle start with a bad Rectifier?
The rectifier is part of the charging system. If you put a freshly charged battery in your motorcycle, and you have a bad rectifier, it won’t stop your motorcycle from starting, but your battery wouldn’t stay charged. The regulator/rectifier on your motorcycle performs two functions.
What are the signs of a bad stator?
The stator coil generates the power for the spark plug and other accessories on small engines Without a stator there would be no spark at all, meaning the engine won’t run. While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. Symptoms are often worsened as the engine warms up.
Are all regulator rectifiers the same?
They all work in the same way though and are pretty interchangeable. Once you get into slightly older bikes, you start to see seperate regulators and rectifiers. If they still have a 3 phase, 12v charging system with magnets, these are interchangeable too, and interchangeable with a modern, ‘one piece’ unit.
How can you tell if a voltage regulator is bad?
The best way to test a voltage regulator is with a multimeter, and what you do is you put your multimeter clamps directly on the battery terminals. Positive read to positive and black to negative. And you said it to voltage, and with the car off, you should have a little over 12 volts. That’s that’s a healthy battery.
What causes a voltage regulator to go bad?
It might be due to a host of other causes, including forgetting to switch off your lights, a problem with the alternator, or simply an old battery that needs to be replaced. But it could also be because of poorly managed current due to a bad voltage regulator.
Can a bad voltage regulator drain your battery?
This could cause the battery to run down over time. Diode failures may also allow AC current to leak into the electrical system. … A leaky diode also can allow current to drain out of the battery through the alternator when the vehicle is not being driven. A faulty voltage regulator can also cause charging problems.
How much does it cost to replace a voltage regulator?
The average cost for alternator voltage regulator replacement is between $351 and $392. Labor costs are estimated between $156 and $197 while parts are priced at $195.
Does a rectifier need to be grounded?
The stock rectifier doesn’t need a case ground. But, some rectifiers need a frame connection to aid the heat sink function.
What makes a stator go bad on motorcycle?
To answer why stators fail, it is because the coating on the windings breaks down, usually because of heat, causing a short which can also burn the fine wire of the winding in two at the short causing an open circuit. The way to prevent failures is to prevent the heat.
