Question about Honda Shadow 400 Motorcycles
1981 honda cm 400 E no spark, was running then just quit and will not start checked for spark by removing plugs no spark then some but very little have new battery can you help me @
Hi, Garryrrobert 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. Faulty run/off switch
11. Tilt sensor needs a reset.
12. Security alarm failing to disarm needs reset

i could not find a schematic of a 96 cbr400rr, so guessing this bike is not from the USA. however, there should be a master fuse near the battery on the positive side mounted to the battery box somewhere. i would check this fuse first to see if its burned out.
also, is battery fully charged? might have to top charge the battery to get good juice if its old (>3 years) and been sitting for a bit.

I would get a test light and check if i had power to my coil and to my cdi module .You more than likely lost powerto one of them .those cdi last for every. check your switch make sure you got power there to. Hope this help

Check the fuses. Next, check for spark but with a new spark plugs. How good is the battery? Try a jump from your car battery. Is the kill switch on? Does the side stand have a kill switch? Is it working properly? Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Be sure you have power coming out of the switch.
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.
Please rate this answer. Thanks Dan!

SOURCE: 1981 honda goldwing wont start
while trying to start an engine, and only the solenoid clicks, there are these 3 things- no juice from the battery, starter corroded contacts(the big cables) or starter is shot. so first make sure the battery is charged, next make sure the cable mounts from battery to starter are clean(no rust), if that is all good and doesnt start , remove starter and have it tested.

Hi, your plug number for an NGK plug is D8ESL As far as the plug socket size it is a 13/16 deep well socket. The gap should be set at .07-.08mm.
