What should battery voltage be on Harley Davidson Sportster?
Attach the red probe of your multimeter to battery positive and the black probe to negative. Set your multimeter to the DC volts position. The voltage reading should be 12.2 volts or higher. This test only checks the battery’s charge level; it does not check the battery’s ability to supply current during engine cranking.
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.
How to check for parasitic draw on Harley Davidson Sportster?
You may notice this as a headlight that remains dimly lit even with the switch off. To check for a parasitic draw: Turn the ignition off. Remove the positive battery cable. Set your meter to read amps. Connect your multimeter in series (one probe on the battery positive terminal, the other on the positive wire) and record the reading.
How to measure current flow on a Harley Davidson Sportster?
This tool measures current flow without being directly connected to the circuit. Place the amp clamp around the large positive wire between the starter and battery. Face the amp clamp with the arrow on the clamp facing towards the starter (direction of current flow). Start the engine and record the reading.
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.

How often does a Harley Davidson battery drain?
Bike is under extended Warranty and they are saying SORRY we can’t fix it! Then they said to get a trickle charger, but I can’t don’t have access to plug it in! It discharges randomly, sometimes its 2 times in a week, sometimes 3 weeks it will stay charged.
Can a motorcycle run without a stator battery?
All the current required to run your motorcycle comes from your battery. The stator system charges your battery and replenishes it. You could actually run your motorcycle just fine for some time without a working stator as the battery has reserve current. Of course, the battery would eventually die.
