1978 Honda Hobbit PA50I

Postby vbskimer » Mon Mar 10, 2008 9:28 am

Hey Gang!

I have just aquired a 1978 Honda Hobbit PA50I.

Trying to get a spark.
I have:
Cleaned the points with sandpaper
Checked all wiring.
Checked all head and tail lights.
Tried multiple spark plugs.
Inspected the ignition coil

Couple of questions.
1. Should the head and tail lights light up if I turn the flywheel fast enough with a drill on the nut of the flywheel? Something that I read in another post.

2. Do ingition coils usually go bad?

3. The points and gap look fine. Is there a way to test the points?

Hopefully I can get this thing running so I can top it out at 20mph. Boo.

Thanks for any advise that you can provide.

Yes, the lights should light up, even when you are pedalling it.

What can I do to troubleshoot the lights not comig on?

Can I bypass the lights while I am trying to get a spark?

What is the best way to go about this?

Thanks

I have a voltage meter. How can I test if I am getting any voltage from my stator/magneto?
Do the headlights have anything to do with faulty points? I thought that if the magneto is turning that voltage should be produced.

Send me an email and I will send you a copy of the wiring diagram.

And yes, any time the magneto is turning, electricity is being produced.
The ignition switch is on as well as the run/off switch on the right handlebar, right?

Mike,

I do have a wiring diagram, but don't have it in front of me at the moment cause I am posting from work.
The key is turned on and the On/Off switch is turned on also.
Do these have anything to do with voltage coming from the magneto?
I was wondering if there is a way to tell if my Magneto is bad by rerouting the electrical to take the lights and kill/ignition switches out of the mix.
Maybe somehow take the electrical down to the minimal circuit needed to run the engine/produce spark.

Thanks again!

Well, the black/white wire that comes out of the magneto goes to the rectifier and then directly to the coil. The engine kill switch and the ignition switch are just grounding devices to kill the ignition circuit.

I am no electrical expert but it looks to me that you could wire the b/w wire that comes out of the rectifier directly to the coil, thus bypassing the kill switch and ignition switch. On another page it shows that the wire coming out of the magneto is black/yellow and the wire coming out of the rectifier is black/white.

That's about all I know

Thanks for all of your help.

I am going to try to bypass all NonEssential electrical and will report back!

You guys on this forum rock!

Oh Well - That didn't work for me.

Hopefully selling the Moped tonight!

Get a lil profit for nothing.

Thanks again SilverFox for all of your insight.

Maybe see some of you at the Richmond rally later this month.

assuming you've correctly tested and done all you have said, very likely something is grounded (shorted) in the circuit. probably a wire has worn through. trace each wire of the whole circuit and look carefully for worn wires, or anything else touching the frame.

also have you verified the plug wire isnt cracked, or the boot not making contact with the wire?

Many times the kill switch or keyswitch goes bad. Unplug the wires to the killswitch
