Often asked: What Should My Volt Gauge At Idle On A 2003 Harley Davidson?

What voltage should a Harley idle at?

I agree, idle should be between 950-1050 to support all systems on the bike and still charge the battery.

What should motorcycle battery voltage be at idle?

Now turn the motorcycle on, let it warm up for a bit, and check the voltage at the battery again. At idle, the voltage should be around 12-13V. At 3,000rpm, the voltage should be no more than 15V.

How many volts should a Harley 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).

Do Harleys charge at idle?

Running your motorcycle at idle WILL NOT charge your bike but in order to get some volts put back into it your battery, you need to get your charging system involved and to do that you need to put the bike under pressure by riding it for a period of time. Buy a Harley-Davidson® Battery Tender!

How do I know if my stator is bad on my Harley?

What are the symptoms of a bad motorcycle stator? The most obvious symptoms of a bad motorcycle stator include no spark, weak spark, or intermittent spark (also known as misfiring). Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced.

Does a motorcycle charge at idle?

Technically, a motorcycle battery does charge while the motorcycle is idling though it does not provide as much amperage as when the motorcycle is at higher speeds. During a normal ride, a motorcycle provides about 13, 14, or 15 amps while idling only provides less than 1 amp.

Does a battery charge while idling?

The answer is ‘ YES ‘, yes the car battery does charge while the engine is idling. As long as the mechanical action of the alternator is taking place; that is, being turned by the engine crankshaft. Then the alternator is producing AC current, thereby charging the battery while your car is idling.

How long should I ride my motorcycle to charge the battery?

Does a bike battery charge while riding? Yes. That’s what is designed to happen, so if your alternator and battery are in fine fettle, a 30 minute ride should easily be enough to top up the battery.

How do I know if my voltage regulator is bad?

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.

How do I know if my voltage regulator is working?

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.

How many volts should a Harley battery have?

The majority of Harley’s build in the last 50+ years are predominantly using 12-volt batteries. However, older Harleys do use 6-volt batteries.

How long can you let a Harley idle?

According to Harley-Davidson, carbureted models should be started on the enricher and allowed to idle for maybe 30 seconds; after that you can push the enricher back in as soon as the engine runs smoothly, and, of course, ride away.

How long should you let a Harley warm up?

Newer Harley models use fuel-injection systems. FI systems are better because they can circulate oil faster and do not need extensive warming up. Still, we’d recommend that you warm up your motorcycle for at least one to three minutes to allow the oil to run through the system and coat all engine surfaces well.

What charges the battery on a Harley?

The charging system consists of three main components: the battery, alternator, and the regulator/rectifier. Your motorcycle battery stores electrical energy for use and acts as a buffer for the bike’s electrical system. The alternator creates alternating currents to run the bike and charge the battery.
