Fix My Hog Answers First check to see if you have any stored diagnostic trouble codes. You may have a bad crank position sensor or a bad ignition. If you have no further clues, try the crank position sensor 1st.

      Take it to a qualified Harley Davidson MECHANIC. Not a job for the faint of heart.

      I see your question was posted in February. Has this been resolved? You say a 1981 4 speed, is it a Sportster or a Big Twin?

    I was riding a backroad about 20 miles from home when my FLHX sputtered then quit. Had plenty of gas and still had lights on dash, but wouldn’t start. Long story short, turn out to be battery voltage too low. Never noticed any problem cranking bike before, but new battery solved the problem.

    I have Harley 2007 Sportster 1200C. I removed the security system and replaced with stock module. Now bike starts and runs for five seconds and shuts off. Any help troubleshooting would be appreciated.

    I have a 2000 Heritage Softail Classic. I turn the ignition switch on and the speedometer does not light up, the odometer does not work and the engine light does not work as well as the turn signals, the neutral and oil pressure light work as well as the head lights. the bike starts and runs. even with the bike running the speedometer and odometer still don’t work. Any suggestions on what would cause this and how to fix.
    Thanks,
    Ron

      My 2006 Sportster 1200L does the same thing. It used to be intermittent but has been like this most of this past summer. It’s always been suggested to me that it is a loose ground somewhere. If you can judge your speed by gear and sound, it’s just a simple annoyance. And of course you don’t know exactly how many miles you have on the bike if that’s a concern.

    I am no mechanic but the 1st. thing I would do is clean all battery terminals and you might be surprised how simple of a fix it might be….good luck…

    You might want to check the run/off switch on handlebars. I had one go bad once and had same findings.

    EXCACTLY what did you do when testing for spark at the plugs?
    How did you arrive at the conclusion that the coil was faulty?

    I have a 2000 FXDX. For the past year it will start, run fine for about 10 minutes, then the electricals shut off. Everything! I’ll reset the ignition and it runs for a few seconds before doing it again, and on, and on, and on. I did nothing electrical to it before it started acting up. Any ideas before I bring it to a shop?

      Don’t need a code reader. Google how to read the codes for your make and model, you can do it from the bike. Then google the codes you may get and read all boards on that topic.

    I have the exact same issue on my 99 Sportster, the ignition module is bad. It can be easily tested by removing the plate to expose the module. with the key in the on position (make sure your in neutral) hit the starter button, if the light on the module blinks while cranking, it’s no good. My bike has only 26,000 miles on it! Screaming Eagle Sucks!

    Tengo una Softail Delux 2008 al salir de trabajar ya no quizo encender pensé que la batería estaba muerta pero en un intento encendió sin problema alguno, al día siguiente ya no quiso encender nuevamente cargue la batería y tampoco, compre batería nueva y la instale y no quiso revise códigos de error y me marca número de piezas P68925-07 y P67439-08 entiendo que uno es el modulo de seguridad pero si recibe señal del llavero pero no deja encender el motor solo deja hacer chispa muy baja
