Always problems with the ignition coil

Unfortunately, I forget to turn off the ignition key and then burns the electronic ignition and the ignition coil.
Now I have the problem that I have after changing from 2 ignition coils always after about 5 to 6 KM misfires the car and the engine is difficult or impossible to start. When the engine has cooled down, it starts again immediately until it is warm again. The last time the car was lying down, I just installed another ignition coil and everything was fine. However, after a few miles the car stopped again. It looks as if both ignition coils have the same error, unfortunately I have no other ignition coil more to check.
Both coils have 5.5 ohms when they are cold.
Unfortunately, shipping to Thailand always takes a long time.
I had set the ignition timing to 5 degrees before TDC, I think that the engine has no elevated temperature. The spark plugs, I had already changed because they sometimes break and run in the cold and no longer work in the warm. For advice, I would be grateful and if someone knows something, if there is not a right electronic ignition, then I would be very interested.

The 24V coils are easily overheated. Most of the aftermarket 24V coils produced today are very easily overheated. When they overheat they quit providing spark. Having spent several years in Thailand I am very familiar with the high temperatures during the day.

An item often overlooked is the distributor vent system. It was put there to evacuate the ionized gases to reduce the chance for an explosion inside the housings. This vent system will help coil these coils in extremely warm climates.

Tubes M & K cool the distributor housing & coil.

Hello Wesk, with my last coil I had no problems. I'm glad to hear that I was already desperate what's going on with the engine. Is there a possibility to buy a better quality and where?

And you know i need the condenser when i install the hall ignition?

and yes, in the night i dont have the problem

If I can not get a coil then I can possibly resort to this solution. I've already tried it with a 12 volt coil, but the put in then 12 volts. But I thought that the ignition temperature is not the same and I would like to expose my new engine no unnecessary risk.

The only 24V coils that will not give you trouble are those still wrapped in the millitary package.

Have you vented your distributor?

And you know i need the condenser when i install the hall ignition?

You do not need the condenser (Which is really a capacitor).

We do have a member of our site "JAM" who has successfully adapted a late model civilian 12 volt coil to the military distributor. Ihave photos of his work in my album: http://www.willysmjeeps.com/v2/modules. ... _album.php

He adapts one of these modern individual cylinder coils to the military distributor.

Here's the link to his discussion: http://www.willysmjeeps.com/v2/modules. ... sc&start=0
