How do you check a Sportster coil?
Set the ohmmeter to read resistance on the “Rx1000” setting. Measure the resistance across the two larger terminals on the coil. The ohmmeter should read between 10,000 and 12,500 ohms. If the meter reads outside of the ranges for either of the above measurements, then the coil is faulty and should be replaced.
How do you test a coil on a Dyna?
Connect an ohmmeter to each end and gently pull and twist the wire to check for breaks. Check the spark plugs. Replace if excessively fouled – do not clean. Rrst check the primary resistance of the ignition coils.
How does the ignition coil work on a Harley Davidson Sportster?
The ignition coil on later model Sportsters. The crankshaft position sensor is used to determine the crankshaft’s speed and position. The E.C.M. or ignition module uses this information to correctly time the spark at the spark plug with the piston.
What should the ohms resistance be on a Harley Davidson ignition coil?
The specified ohms resistance for the primary of a 2000 carbureted Softail will not be the same as the primary of a 2005 Ultra. Therefore, it is important to use the correct electrical manual for your ride. When testing your Harley Davidson ignition coil you will be testing ohms resistance.
Why is my Harley Davidson Sportster not igniting?
One of the most common sources of electrical problems is the battery. Test the battery’s state of charge and current capacity by reading Step 2 of the article Electrical Diagnostic Guide. If no spark is present at the end of the spark plug wire, the air/fuel mixture cannot ignite.
What are the symptoms of a Harley Davidson ignition coil misfiring?
Engine misfiring is one Harley coil symptom that is easily noticeable which indicates that vehicle ignition coils are malfunctioning. Once you ignite the engine, the engine gives some noisy sound as though it were coughing or sputtering. Usually, if your bike is at high speed, the engine will jerk and spit, making some unpleasant vibration.

Where is the starter on a Harley Davidson 883 Sportster?
Connect your red probe to the solenoid positive wire. This is a fat 12 or 14 gauge wire on the cylindrical portion of the starter. Connect the black probe to a known good ground. 12v should be present in this wire at all times. Figure 3. The starter location on a 883 Sportster.
