Kreidler tm 1978

[JIMMYS]

Hello again my friends after a long time.
After these COVID19 days I decided to do a not small ride with my export model 1978 tm.
I push it too much as I reach to a 1604 meter mountain and there it started to happen this: with 1st gear it gets too hot and it get off..after 1 minute it starts again and to the next 2 km off again, wait 1 minute and starts again e. t. c.
It has all the standard parts and by now this didn't happen before.
Is the problem the coil?

You say this didn't happen before, but have you driven at such altitudes before without problems?
At high altitudes the air becomes thinner and has les oxygen.
If I remember correctly: thin air makes engines overheat more easily.

So couldn't it just be the thin air?

Je zegt dat dit nooit eerder is gebeurd, maar heb je eerder op zulke hoogtes gereden zonder problemen?
Op grootte hoogtes wordt de lucht ijler en bevat deze minder zuurstof.
Voor zover ik me herinner zorgt ijle lucht ervoor dat motoren makkelijker oververhit raken.

Dus zou het niet gewoon aan de ijle lucht kunnen liggen?

It seems like a ignition problem. High attitude’s are no problem.

Gaat hij alleen maar rijk van lopen.

Yes it is not the original Bosch but it will do his job.

Yes maybe it was the air that was the cause of the problem, because after the mountain and near the sea I push it 70 for 3km and happened again

ore easily.

It seems like a ignition problem. High attitude’s are no problem.

Is it wise to start with the ignition coil, or the contacts first?

[JIMMYS]

I check the spark : good, the sparkplug brown, just fine
The ignition coil is outside, over the cylinder, so it is the coil or the consedator?

[nozems]

I think the condesator. Try to replace that en then try again.

It’s also possible to measure your ignition, but i dont know how to do that and what good values are.

Ask Tjerry (Enzo)

I think it is a problem of the ignition coil(s).

It is a typical behavior, if the engine is cold, no problems. If the engine is hot, your ignition does not work.
Because the coil expand, if the coil becomes hot. If there are problems within the winding, there will be contact problems within the coil, if the coil becomes hot and expand.

If the condenser is defect, there will be big sparks within your contact, so that the contact will be burned in a short time.

Please consider:
Your ignition has two ignition coils, the black coil above the cylinder and another coil within the ignition (see first pic, big coil with a blue cable).
The coil within the ignition delivers the energy for the black coil.

At first I would change the black ignition coil.

Thanks s lot, I will look at it and I ll tell you what is the problem.
Thanks again

At the second photo the contact with number 15 is for the connection with the inside coil and the number one if for graunted?

[JIMMYS]

Is this the right connection?

[JIMMYS]

OK I find it, but at my Kreidler the connection was opposite, is that a problem?

[Enzo-tvdzijden]

why did you not look in the TM wire connection

you see 15 is massa
and 1 is the blue ignition coil

You create problems

[Enzo-tvdzijden]

and 1 is the blue ignition coil

Enzo I am confused
The 15 is for earth, as the TM wire connection. Right?
Why the Bosch and another mechanic here told me the opposite? It works and for the 2 ways but I don't understand why I see two different ways.

Look good i made a correction. faster than your quote. You can read and self see in the picture. With a little smartphone the 1 is next to the 2 button

Thanks

Enzo I notice your correction. I understand that.
My question is that as I observe the ignition coil works with 2 ways. I put the wires as the Bosch schedule and I didn't see any difference. But the TM wire diagram prefers another way, the way you say.
Finally the question is that it doesn't matter finally the connection?
