Answer

CHECK: proper voltage to the coil.
Spark plug condition/gap
Condition of plug wires
Condition of battery
Test for spark on front & rear cylinders.
If you only have spark on the front cylinder, swap plug wires (front to rear, rear to front ). Now see if you (only) have spark on the rear cylinder.
If you do not have power to the coil; Use a small jumper wire and power your coil directly from the battery. This will will bypass your harness and switches.
If this gives you proper voltage/spark, you need to repair a dead short or break somewhere in your wiring harness.
If you have a Tachometer, disconnect it. A bad tach can interrupt proper coil function.

    I’ve got a 2003 wide glide. The gas gauge lights up and gauge goes to full and never goes any lower, even when fuel is low. I replaced the gauge and it does the same thing. How do I get into the fuel sending unit?

    My Harley is a 2007 883 sportswriter.
    It is working with a fob and when I am trying to start the Harley the alarm goes off and don’t want to start.
    Please can you get me some advice.
    Can I remove the alarm and will it still start without the alarm and fob.

    Hello, my 2007 sportster 1200 has trouble starting.
    The battery is good, but when I hit the switch nothing happens. Just a low click. But when I mess with the shifter it starts eventually, but honestly I’m not sure what it is that I’m doing to get it to start. It just starts or doesn’t, and eventually turns over but again i don’t know what it is that makes it start or not start.
