Happy-Time Magneto Installation Video

which wire goes where ?

Hi Large,
I read that post before, and it seemed to confuse me a bit.

I'm no expert on wiring these motors or motors at all,
in fact I'd go as far to say I may have caused more issues
than solved so far with my bike.

The reason I'm posting this is to be sure myself.
IE get somene to confirm who knows more than me.

But I see three simple wiring choices here.

1. Wiring the white wire to Kill Switch. ( I thought this was called Overloading)
2. Wiring Direct to the CDI ignoring the white wire and Kill Switch.
3. Wire the Blue wire to the Kill switch. (I thought this was called shorting).

If you see this link

At the start of the Vid, I show my initial Setup of 1.

Then I wire in the format of 2.
You may have to freeze the play to see this.

Option 3
I am not sure how to setup this option, but think I could guess it.
(famous last words)

I think a wiring diagram/pictures will help here,
as words are harder to grasp when new to this.

I'll look to create the diagram, even for my own benefit.
Can anyone confirm my wiring in 1. and 2. above being valid ?
You will need to check the vid.

the way it works is...
the green/blue(+) and black(-) have to be connected in their own side of the loop (circuit)
if you connect the blacks together, and then, connect the toggle switch in the green/blue side, you can see how opening the switch (off) would break the loop...killing the engine from no spark, rather than grounding thru the magneto, as in the stock kll switch

btw... I have been doing this since last spring (my deviate days)
I started doing it after my kill switch shorted and zapped me big time

I never even realized the benefit of longer mag lifespan... but it helps

hmm,

as an update, my bike is a statue.

here's the diagnosis.

The electrics:
I get no spark,
the coil resistance has dropped.
to 80 Ohms.
Occasionally it hits like 240 odd when you poke
the magneto solder points.
I have changed the CDI for one that worked before,
which made no difference.
I'm not sure how to fix this.
at least i know its not worth trying to start it.

the emotions:
pure depression.
I'm about ready to rip this motor off the bike
and chuck it in the bin. after so long,
i'm still have no ride.

the reality:
maybe i could buy a spare motor and use this one as parts.

the interaction:
I had a chain saw user help me diagnose the bike mag,
was interesting hearing his view/insight into the motor.

ok, so there's a cross section of the last week.

anyone have sugguestions or questions, post away.
as I'm outa ideas.

Try this; ( process of elimination test )
Clear fuel tank or cover fuel lines and fuel tank.
----------------------------------------------
1. Remove lead from spark plug.
2. Remove spark plug from motor.
3. Use a philips ( star ) screwdriver and place the tip of the screwdriver in the lead where it connects to the spark plug.
4. Using the handle grip of the scrwedriver, place the middle stem of the screwdriver about 1/8 " from an air fin near the spark plug hole with one hand.
5. Peddle with the other hand so the engine turns.
6 While it's turning, check to see if there is a spark between the stem of the screwdriver and the fin.
7. If there is a spark, then place the lead back on to the spark plug.
8. Place the the spark plug on the same fin and turn the motor over again and check to see if it sparks at the electrode end.

If it don't spark at the spark plug end, but sparks with a screwdriver, then try another spark plug and try a new lead.

voltmeter query/test.

Hey Bolts,

Thanks for the test.

I tried my standard plug test just after I installed the mag,
IE Place plug on a fin and wheel the bike around
and it showed good spark across gap.

Then a couple of days later, its shows up no spark.
I Have tried a brand new plug with no spark.

Something I didn't mention is that I tried a voltmeter test
across the magneto, which gives a more quality reading.

That is,
connect Blue magneto cable to the red voltmeter cable.
connect Black magneto cable to the black voltmeter cable.

Put meter on 20 Volt option.
Hold back wheel up and pedal bike by hand.

It showed a variable reading 2-3 Volts, which I think (not know) is too low.
Maybe I could connect voltmeter to CDI output, and pedal by hand.

What voltage should that show on a functional magneto ?
Also, one other question,
Is it possible to test the CDI with a multi-meter ?
IE, Is there a resistance or voltage value the CDI should have ?

so my brand new magneto is dead.

 

[BoltsMissing]

Can you supply pics. of the Mag. in all angles, to show wires etc. ?

I'm wondering if a wire is frayed and touching earth or something unoticed.
Also others can take a look and see obvious signs or faults during and after install.

All the best....,

Um, no...you want to test for resistance, not necessarily voltage output. Didn't you do the test for your magneto on a previous occasion?

Place volt meter on the ohms setting and 2000 on the dial. Place leads onto the blue and black: It should read 320ohms(even a bit lower) - mine read 364which is good. Lower readings equals bad magneto.

Try this: go to supercheap and get a set of drill attachments for sockets. There should be three for the different size sockets that you may have for your socket set (only seven bucks). You plug the right size socket onto the end of it (the other end into your electric/cordless drill). Now, where your magneto is, there is the flywheel nut and place socket onto this. Make sure that you take your sparkplug out and earth it out to the head & turn on drill (make sure its clockwise). You should be able to play around with the sparkplug so that its earthing properly to get a spark happening. Please be gentle when doing this otherwise its possible to damage motor IE. make sure drill is square before turning drill on. If you use cordless drill, its better because it has less power. If your really game, put sparkplug back in and do the same and motor may even fire. Be quick and remove drill attachment in time in case it does start!!! This just saves time having to pedaling/pushing around everywhere. All the pros out there may go against the above advice, but its up to you in the end.

I know what your going through. I tried and tried to get a spark out of mine but wouldn't but there wasn't any thing really wrong with the bike. Just operator error.

Take your time and by the way, the CDI unit should read around 2.3 to 2.4ohms when you have the multimetre on the right setting.

hi watcher,

I like that idea, simple yet powerful.
its a test that can be done by one person.
I can see my next vid already.

Um, no...you want to test for resistance, not necessarily voltage output. Didn't you do the test for your magneto on a previous occasion?

I've done both voltage and resistance tests ( before and after install)
thanks for the CDI test.

I had 218 ohms at the start now 80. you're saying I should have had
320 ohms at the start.
So maybe it was always faulty.
the motor had low power when running,
compared to when I first rode it.

Bolts:
The install I did is shown in the vid link at the start of this post.
[90 pictures there]
you can see the meter reading there for resistance.
the whole install start to finish.

thanks for the comments.
I'll try the ideas when I can.
