I thought many of you could find this Honda Express scooter wiring diagram useful. This honda moped wiring schematic shows everything from headlight, to moped battery, to alternator, to scooter tail-light, and more.

JFK,
I need help! I've been working on my 1978 Honda Express for a month now and have it to the point where it should run, except for one problem. The spark plug isn't sparking. I got a new battery and charged it. So I'm guessing there has to be something wrong with the ignition coil? Do you have any ideas? I just want my express to run!

Thanks,
Silas

P.S. you can respond to my email if you'd like: xcsilas.freeman@gmail.com

Here are some guesses or tips that might help:

- Get a new spark plug (if you haven't)
- Check spark plug gap (page 8-6 manual)
- Clean the moped ignition point (see one of my recent posts for how to video on that)
- Take off all your wiring connectors and clean with wire-brush and electrical connector cleaner... then re-attach. Could be corroded connector.
- Check out the "Contact Breaker Point Gap" and other ingition inspections/adjustments in Honda Manual (page 8-4)
- Try testing ignition coil (see page 20-2 in Honda Shop Manual - found on this site)

Let me know how it turns out.
