Start with the Simple Stuff
Before you embark on a complex electrical diagnostic, it’s wise to begin with the rudimentary steps. Inspect your spark plugs as a starting point; if they are recently installed, confirm that they’re of proper type and correctly gapped.
The next step is to assess your spark plug wires. Look out for the resistance measurements that are provided in your Harley Davidson manual, and make sure they meet the requirements. If you observe any damage or wear on them, have them replaced right away before continuing with further inspection.
Check the Ignition Circuit
If the spark plugs and wires look good, it’s time to inspect the ignition circuit. Begin at the battery and make your way towards the spark plugs. Examine all components of this system including: kill switch, coil, as well as an ignition switch for any potential issues. You can get access to primary/secondary resistance specifications from a user manual or ask someone with knowledge in these matters for assistance.
Look at the BAS and CPS
After you ensure that everything in the ignition circuit is working properly, it’s time to assess the BAS (Bank Angle Sensor) and CPS (Crank Position Sensor). To test your CPS, attach a VOM across its two wires while cranking the bike. You should notice an alternating current signal indicating proper functioning of this AC generator.
Check the TSSM
With a TSSM (Turn Signal Security Module), it’s essential to first examine the part number. This will allow you to identify if it is indeed causing an issue with your ignition, as certain models will disable the switch should they be malfunctioning. Furthermore, when you turn on the ignition and observe flashing lights – this is indicative of a tripped alarm that won’t even permit your bike to crank over. With all these signs present, there’s no doubt that a faulty TSSM is likely at fault here.
Other Things to Consider
After exhausting the above steps and still failing to determine the cause, double-check any fuses or wiring for breaks or tear. Be sure that your battery is completely charged and functioning properly as well. If you recently installed aftermarket accessories, verify whether it could be causing electrical problems.
