What to do if your Harley Davidson Sportster has an electrical problem?
Move your ignition switch and coils from the front of the bike, under the tank, and open up the whole look of your Sportster. Know where your fuse box is and which fuse does what, because it is the first place to look when you have an electrical issue.
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 can I identify stator problems in Harley Davidson?
Take a test light and clip it to the negative terminal of the battery and then touch first one pin and then the other on the plug that goes to the regulator. If you get even the slightest amount of light from the test light the regulator is toast.
Where are the ground wires on a Harley Davidson Sportster?
There is one main ground wire routed from the battery’s negative (black) terminal to a stud on the primary case. This is the largest of the ground wires on the Sportster. Start with the larger ground wires first, as they will have the greatest impact on your electrical system if a failure occurred.
How does the electrical system work on a Harley Davidson?
