Question about 1993 Harley Davidson XLH Sportster 883
I tried to start my bike but it will not start. checked the fuel and spark. fuel is good but the coil shoots only once. please help!
It sounds like you are losing power to your coil. This is why it will fire only once and then quit. To verify this, connect a test light to the small connection on your coil that has the white wires runing to it. Turn on the switch, the test light should come on. Now press the start button. If the test light goes off and stays off, this is what is happening. It may come back on after a few seconds. If so, you have a short somewhere causing your igniton circuit breaker to trip or the circuit breaker is bad or you have a bad ignition control unit. The control unit is very difficult to diagnos since Harley uses a particular type of meter to do their testing with.
Using a DVOM (digital volt ohm meter) test the resistance of the primary circuit of the coil. Remove the white wires and pink wires from the small connections. Now, put the meter in "R X 1" scale. Touch one lead lead of the meter to each of the connections. You should read about 3-4 ohms of resistance. Any more or less than this, your coil is bad and you need a new one.
