Question about 1980 Honda CX 500 A

1 Answer

1980 Honda Cm400a No spark

I rode the bike home, parked it, went to ride again, it would not start. I have new plugs, coil, swapped the cdi, swapped the wiring harness( not the modules, solenoid etc), swapped off the right throttle, kill/run control. The bike will crank but won't start. I pulled a plug, and with it in the wire cranked the engine nothing.
I am not sure what else to look at. I have searched google and see references to bypassing the kill switch but am not sure how to do this.
Any assistance will be greatly appreciated, it is too nice here to be in my car !!!!!!!!!!
this site does not list my yr and model I need

Hi and welcome to FixYa,

Bypassing the kill switch means removing the connection of the black / white wire either at the emergency stop switch (kill/run), ignition switch or preferably at the CDI connector.

Additionally, you can try:

  • start with the side stand up;
  • check/wiggle the 6 wires coming from the stator going to the CDI.

Would appreciate a postback on results / updates.

Good luck and thank you for using FixYa.

Hi, Anonymous and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Tilt sensor needs a reset.
11. Security alarm failing to disarm needs reset

Bike stalls after 45 minutes riding


HT coil, 99% certain, the one that's on the end of the plug lead. electrical stuff, particularly HT coils break down when warm. if it was a CDI unit it would likely go pop and that's the end of it. you can get the coil tested, or get a second hand cheap one or borrow one to see if that's it. I used to test them by putting them on a radiator to get really hot, faulty ones would give up real quick then.j

No spark


Check the side stand kill switch if your bike has one. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. Check the fuses. How good is the battery? Try a jump start from your car battery. Is the handlebar kill switch on? Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Install new spark plug.

If that doesn't do it, check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop. You can screw up a CDI unit checking it yourself.

No spark


I too have a 1087 Honda Shadow and after we rebuilt, cleaned and painted the bike, it would not spark.

Behind the battery, check the CDI box. Look inside and shake upside down, looking for the presence of water. Once we completley dried out the unit. The bike runs like a champ.

the other day I rode in the rain for 160 miles. Engine died. Went to the CDI, water was there. Dried it out and again the bike runs fine. I am going to seal my cdi unit now. and hopefully the problem will not come back.
