poo'joe not sparking

Hey gang I have a 102 sp peugeot. I got it at a swap meet real cheap and have been cleaning it up. Thanks to zippy and Don in ohio I managed to check and find out that I have great compression and it seems like everything is now working (after replacing all the cables) Except for the small ( coughs) fact that I have no

spark. I took the cover off the magento??? Well it looks like a mini alternator of sorts.. looking at this I would swear it was brand spanking new. Also the plug is pretty new by looks. I soaked almost everything

I could get the little straw near in carb and brake cleaner. Also I did try doing it with the switch on and off ( lol zippy) hehe The plug wire does have continuity

Now what???????

Re: poo'joe not sparking

Does it have points ??


Then clean and set the points like it says in "How to fix Your Moped"

(click on 'resources' then 'articles' above)

Re: poo'joe not sparking

that would be much easier if I had a clue what the points looks like.

I'm totaly lost sorry for being lame guys.

Re: poo'joe not sparking

I also read somewhere that some mopeds if your missing a light will not spark sometimes. well is this true becuase I have no headlight bulb. Thanks.

Re: poo'joe not sparking

On some peds the points circuit goes thru the taillight... so if the taillight is out.. you also lose spark.

This is a set of points... they are inside the flywheel on one side of the motor.

They are only about an inch long (this photo is way bigger than lifesize).

The actual points are 2 small round metal pads touching each other in this photo.

The long straight metal arm is what moves to open and close the points as the engine turns.

Look through the holes in the alternator flywheel, you should see a pair of electrical contacts which are opened and closed by a cam on the shaft. If you can't see this, you may have electronic ignition. Mentioning the year of your ped might help someone who knows Peugeots to help you.

Btw, I am not aware of the Peugeot having the lamp interlock, but if it does, it is usually the tail lamp.

It's one of those fancy foreign words.

Re: poo'joe not sparking

Hey should the puegeot spark with the decompresion button not pressed. I think it should right?

here is my thing i think the points are right.. on the bottom of the tank agianst the frame some idiot must have had a small crack there and decided to fiberglass the hole up.. no biggie normaly but he acutaly fiberglass and resined over all the wire and the brake clutch throtal cables.. I know for sure it messe dup all the manual cable becuase the gas lever wont budge and the brake lever wil not even move..

I ripped the brake cables off as best I could from the fiberglass cut and in hooke dthem and wired in new cables now they all work fine.. however my electrical wires are still fiberglassed under partly. What a mess!. I think that might be where my problem i but before i go rewireing the ped without a manual i want to make absoultly certain. I would like to test the spark plug wire butit is actualy connected to the coil it wont come off (almost like it is all one piece.) I wil;l check and reset the points tonight or tommorrow. but is there anything else to check? Thanks a bunch.. i feel lost.. the motorcycle shop here in hicksville wont touch a moped... :0(

Yes to your question about the decomp, it should spark either way.

If cleaning the points does not work and you can get your hands on a vom, here are some generic instructions for checking the ignition system and coil testing .

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.
