What kind of ignition coil does a Harley Davidson use?
Test the Harley Davidson ignition coil with a multimeter. Harley-Davidson uses a mutual induction-type coil in all its models.
What causes a coil on a bike to fail?
Insulation breakdown of the internal windings is the main cause of coil failure. Test the coil after it has been removed from the bike. 1. Set the multimeter to test for continuity. The symbol for continuity on the meter is usually something that indicates sound. It may be a sound symbol along with an omega or a sound symbol and a diode symbol.
How many ohms are in a spark plug coil?
Set the multimeter to test for ohms in the 1,000-ohm range. Place a probe on each of the secondary winding terminals within the spark plug wire towers on the coil. The meter should read 5,500 to 7,500 ohms. 6. Replace the coil if it fails any of these tests.
Where does the spark go on a dual fire coil?
Dual fire coils send spark to both cylinders, all the time. Regardless of which cylinder is on the compression stroke. Single fire coils designate spark to only the cylinder that is on the compression stroke. Spark is delivered to one cylinder at a time.
Is the ignition coil on a Harley Davidson repairable?
The ignition coil on a Harley Davidson motorcycle is an essential component of the ignition system. It consists generally of two sets of wires that are wrapped around an iron core. This component comes sealed, and is not a repairable item.
Which is the positive side of a Harley Davidson coil?
Discussion in ‘ Electrical ‘ started by fpd4308, May 12, 2010 . I was wondering which side of the stock harley coil is positive as neither post is marked. I have heard that as long as you put all the positive wires on one post and the grounds on the other it doesnt matter but wanted to check with the experts.
What should the ohmmeter read on a Harley Davidson ignition 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. Sometimes a coil will only give a faulty reading when it is hot from riding.
