i know this is in the wrong forum......but i also know that alotta you cool moped riders don't look at the buy/sell section... but my friend needs help with some parts....he just bought a sweet 1978 honda express and he's can't find a coil and condensor......probly because it isn't being made any more......well mabey in one loyal moped owners bacement.....if you own a honda express or have the parts that will fit then email me back or reply

I don't have your parts, but I am curious. How are you so sure that you need a coil and condensor?


Re: help!!!!!!!!

im not....thats just what he said....he said he's replaced alotta other things on it that could have been the problem....and his dad said thats what it needs (he owns a harley) so im just taking his word...i might take a look at it to see if thats what it needs.


save him some time and money

ho-hum... save your friend some time and money... Mr Harley probably doesn't have a clue... and likely the only thing that is wrong is the points need the 'sandpaper clean-up' as stated in my guide.

Do that FIRST... on any non-sparking ped... THEN proceed to buying parts.

(buy a spark plug first...)

already bought a sprk plug.....i looked on (best parts site) and i found one for him for only $25....and its high says its universal so it should work...what do u ppls think???


What do I think ?

I think you should follow the advice in my post above and clean the points BEFORE you buy anything.

Or do you want him to buy a coil for $25 ... and then STILL not have spark because the points are still dirty ??

Re: save him some time and money

try it out, but when taking advice for mopeds from people who have motorcycles can be bad.

b/c i have a ford escort doesnt mean i know whats best for a porche... same concept applies.

some problems could be just simple irritable ones that could save you time and money, as fred mentioned aboved.

Re: Ask if

..the switch on the handlebars is tuned to the "Run" position.

Are all the wires inside the headlight hooked up correctly?

Check the obvious before buying parts. Electrical parts are nono returnable!


Re: What do I think ?

Fred your so funny..

you crack me up... you kept telling me when I was green to look at your guide.. it answers all problems... I looked and I looked and after fiddleing with the moped and getting it running; I went back and sure enough everything I figure I did to get it running was useless becuase in the end it took a thin strip of sand paper and some carb cleaner.

There is lots of good advice here that I agree with. I also think that there are lots of things to spend $25.00 on that are much more worth while than a spark plug. I have never spent more than $1.00 for a plug and have had no problems.

Consider the number of posts on this forum regarding plug heat range and ask yourself how a "universal" can cover variations in this when it is governed by the mechanical construction of the plug.

If you know someone who can use a VOM and this ped has magneto (no battery needed) ignition, try the following.


If you have a vom, check the ignition components as follows:

Disconect the wires from the points. One of these wires goes to the magneto ignition power coil. You should read a low resistance to ground on this wire, 1-2 ohms.

Another wire goes to the condensor, read this to ground on RXMAX, that is your highest resistance range, the needle should kick, then settle down to infinity. Reverse the vom leads, same thing should happen.

Another wire goes to the ignition coil primary, this connection is also connected to the kill switch. Disconnect the kill switch wire only from the ignition coil, the wire to the coil should read 1-2 ohms to ground.

From the wire to the kill switch, to ground, you should read infinity with the switch in "run" and 0 ohms with the switch in "stop".

Connect the vom from ground to the wire terminal on the points and make sure they are 0 ohms when closed and infinity when open. This seems dumb, but sometimes points that look clean do not connect.

Re-attach all of the wires to the points. Disconnect the wire from the points at the ignition coil. Measure this with the vom, it should read near 0 ohms. If your meter is sensitive enough, you should see a slight deflection of the pointer as the points open and close.

With the vom still attached and set to about 12v DC range, spin the motor by hand. You should see some deflection of the meter needle.

Pull your plug (spark, that is) and make sure the piston is at or very near the top of it's stroke when the points open.

Re-connect the coil wire. Measure from the plug cap to ground, you should read 5-15k ohms. If this is infinity, unscrew the plug cap from the wire and read through it. This should be 5-15k ohms, if it is open, replace it, if greater than 15k ohms, it may still work, but replace it with a paper clip for test starting then re-install it after you get the ped running.

Read from the end of the plug wire to ground through the coil, you should see 1-5k ohms. If this is infinity, the coil is bad.

Lastly, using the ohmsX1 scale, verify that all of the grounds really are.

None of these tests are guaranteed to indicate a problem, especially where you read coil resistances and they seem ok. Substitution is the best test here.

To test the coil, connect a spark plug from the plug wire to coil ground, connect an ignition condensor (any will do for this test) between the points terminal and coil ground. Connect the negative of a 6V battery to coil ground and touch the points terminal momentarily with the positive lead. This should give you a spark at the plug.

Re: What do I think ?

Oh god man... 75 percent of all the questions here would be solved by simply cleaning the points and cleaning the carb.

I'm sure I sound like a cuckoo clock by repeating the same answers over an over again.

Re: What do I think ?

No,Fred! More like a wise old `different kind `o bird, I think. Hey! If it's true, it always bears repeating. (:^)

wow thx ppl

wow when i said "what do u guys think" i didnt think so many ppl would give advice..... thx everyone and ill tell my friend to try everything you said... its the real mopeders like you guys that keep this forum cool


crap didnt log in then

it was me in the last post (only do this cause of the hackers)....where have they been ne way???
