You asked: How do I know if my motorcycle voltage regulator is bad?

What are the symptoms of a bad voltage regulator on a motorcycle?

Symptoms of a bad motorcycle charging system

  • Motorcycle won’t start. This one’s the big, obvious one. …
  • Spluttering as you drive. When voltage is low, it’s hard to keep the motorcycle running.
  • Lights light up and dim as you rev. …
  • Battery warning light comes on.

How do you tell if your voltage regulator is not working?

Symptoms of a bad voltage regulator may include:

  1. High voltage output.
  2. Low voltage output, sometimes.
  3. No voltage output.
  4. Lights dim or flicker.
  5. Faulty high-beam headlamp bulbs.
  6. Engine working erratically (weak or flickering ignition system)
  7. Adding water to the battery frequently.

What makes a voltage regulator go bad?

They usually fail because they‘re under rated for the constant current draw. Running the motor with the battery disconnected – or even a poor contact on the battery terminals – can also blow them.

How many volts should a motorcycle stator put out?

For example a 32-amp stator should put out 18 volts AC (VAC) per each 1000-RPM. At 2000 it should be 36 VAC (18×2). At 3000 RPM it should be 54 VAC (18 X 3).

Can I drive with a bad voltage regulator?

A bad voltage regulator may cause it to simply not work or behave erratically. You’re not likely to be able to start the car at all, but even if you could, it wouldn’t be wise to do so without knowing how fast you’re driving, how much fuel you have left, and other critical info.

What happens when the regulator rectifier goes bad?

In general, there are two primary ways that the regulator rectifier can fail. First, the diode can burnout and cause the battery to drain. … 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.

Will a car start with a bad voltage regulator?

Dead Battery

A burned-out voltage regulator will diminish the vehicle battery’s ability to charge or stop it altogether. … If the battery is recharged, the vehicle will start, although the faulty voltage regulator will only cause the battery to lose power rapidly.

Does a rectifier need to be grounded?

Re: rectifier grounding

The stock rectifier doesn’t need a case ground. But, some rectifiers need a frame connection to aid the heat sink function.
