peugeot 103 no spark

help a newbie out.

i bought this moped and from somebody who seemed to know what they were doing.

i cant get a spark.

i replaced the condenser and the points (new from treats).

the ignition coil and lighting coil are not stock from what i can tell (??).

also got a new spark plug.

maybe my wiring is wrong because i am confused by all the electrical diagrams.

on the first exploded diagram here i am seeing 3 wires going to the condenser.

however, i followed the wiring from here in order to try what is recommended in the video to get a spark. didn't work.

https://www.mopedarmy.com/forums/read.php?6,4186329,4186329#msg-4186329

should my ignition coil be attached to my condenser instead?

here is mine:

if you cant see, ive got this order>>>

spark plug > ignition coil > points > condenser > ground(blue wire)

my lighting coil isnt attached to anything. (if i wants lights, where would that attach?)

im ready to ride and appreciate the help.

Re: peugeot 103 no spark

i gotta put in a word for trying to be crafty, it makes life easier the cleaner something is put together, yours is a mess. anything on the hot side of your ignition coil that gets grounded is gonna kill the spark. that includes the wire thats obviously rubbing on the flywheel. blue wire to ground. not to condenser!. organize tuck from danger!

Re: peugeot 103 no spark

YES to cleaning up that mess like Pat says.

The white wire I traced in yellow needs to be tucked in safe and where it joins the points lug screw it cannot touch or ground on any other part.

Get rid of the oversized crimp connectors at the condenser. Just use bare wire at first till you find your spark. Build a nice clean wire going to the points lug (traced in orange).

Get rid of that huge kill wire for now (green arrow) you can add that later.

Most of all (red arrows) no bare wires can touch the outer casing of the condenser.

Then set your timing using the poor mans method from the Wiki.

Report back.

Timing

Re: peugeot 103 no spark

thanks for making it obvious. i was expecting more trolling. (edited)

Re: peugeot 103 no spark

If all that fails try unscewing the whole spark plug boot and strip bac a tiny bit till you have clean wire and hold that close to the stator to simulate a spark plug.

Re: peugeot 103 no spark

that look any better?

do i have to have the kill wire on it when i try and test it like the video?

i tried 9-volt testing it the way it is in the image but i got nothing still...

Re: peugeot 103 no spark

i figured out how to tuck the white wire away more...

i'll give your other suggestions a run tomorrow.

Re: peugeot 103 no spark

No you dont have to have any other wire on it to make spark.

You may have to get a continuity/multi meter to pursue this hobby.

This one was free at harbor freight when the lady clerk threw it at my head for insulting her.

Re: peugeot 103 no spark

ive been borrowing one. those wires look decent?

Re: peugeot 103 no spark

much much better, for spark points gotta just open, n spark plug body gotta be grounded

Re: peugeot 103 no spark

still failing to get a spark.

i put it all back on the bike and added the kill wire which i have grounded (maybe thats wrong??)

time to strip back the boot.

A grounded kill wire kills the spark .

Re: peugeot 103 no spark

eliminated the kill wire. still no spark.

did the timing again and again and again. no spark.

not sure what exactly youre recommending here... im not seeing how the boot unscrews. wondering if its worth cutting to get bare wire cus this part could be faulty? any other recommendations?

Re: peugeot 103 no spark

You installed new points . Did you ever clean them ?

It only takes a fingerprint to fowl them .

I use brake cleaner or electrical contact cleaner , followed by running a clean dollar bill between closed points .

Re: peugeot 103 no spark

That original red 5mm plug cable screws into little barbed spikes that are in the ends of both that coil and the original boot. If they get corroded or burned they can be trouble.

You can unscrew the wire ans snip off a 1/4 inch to get fresh wire.

Also since you have your friends meter do this:

Remove just the white wire frome the points lug but leave the black condenser wire in place. Put a slip of paper between the points contact. Now use the meter to test for continuity between the points lug and the stator plate. You should have NO continuity. If you have any reading at all it means that your condenser or your points are internally grounded and wont work.

If you dont know how to set your meter to test for continuity just ask. (edited)

tried the cleaner and a fresh 5. nada.

Re: peugeot 103 no spark

Have you tested the condenser to insure its good ?

Just because it's 'new' doesn't guarantee it's as it should be .

Maybe try your old one ...

the "old one" is also a "new one"

i got a few days ahead of me to get some work in.

Re: peugeot 103 no spark

Test both of them or keep on guessing .

Seems better to know what's what .

Re: peugeot 103 no spark

Angela Cutshaw /

Isn’t there a way to hot wire just to see if there is spark and not worry about if lights etc are working.? I did get spark that buzzed my whole body yesterday but nada today

Re: peugeot 103 no spark

Test each component with a ohm meter. Exciter coils are mostly 1-2ohm, spark coils are 1-2hm across the primary and 3500-4500k testing the secondary to common terminal. Check points with no wires attached for go-no go continuity by opening closing contacts. Check the condenser if it will charge and unload with a ohm meter. (or if CDI check trigger coil 1-2ohm). Antiparasite cap should be 5ohm and dont use one if you are using a resistor spark plug.

USA wiring schemes have the core end of the windings on the ignition coil grounded via the tail light circuit or horn or brakes. Check the wiring diagram for which scheme or make a jumper from the core end to common (ground).
