Caps came today. This project will be delayed for a while as spring finally arrived. I will be giving a cap and the directions to a friend to repair his 056. Thanks for all the work on this problem, Foggy
 
Rick-- thanks for the feedback! Did you have any troubles implementing the fix? Others will certainly be interested especially if they own a "dead" ignition.

Stihlx8--- SPREAD THE WORD!!! Lets see if we can put this ignition issue behind us. AND YOU WILL "GIVE" THE CAPACITOR AWAY???? He must be a good friend..........you could sell that little blue cap for $25 + : - )

Great solution and write up Foggy! Many thanks. I'm off to buy an 056 mag2 tomm. No longer in fear of the dreaded ignition problem. Cheers, Matt.
 
Just a quick thought have you had a look at the echo 610evl coil prob,:rolleyes:
there would be a lot of people on AS that would be VERY HAPPY with a fix ;);)
Me as well.(mine still works ):confused:
for how long is the ?:(:bowdown:
 
No, I have not looked at anything other than what I posted in this thread.

But---------IF SOMEBODY SENDS ONE TO ME......................AND NO, NONE, NADA GUARANTEES ON MY PART.......I will take a look at it and that means ripping it apart. I have no way to test it but there are some things I can do though.

That is a great fix! Lakeside53 would be proud of you. He fussed around with some of those old Bosch ignitions on some amazing 056 restorations. I sure miss him. The thread is linked in my sig, but the pics are gone due to something that happened on this site a few years ago.

I am lucky to have gotten three 056s, and they are all mag 2s with SEM ignitions. Two of them work, one was in a basket.

Mag 2 is most likely SEM ignition, which I'm told is also used on the TS 360 concrete saw. I don't know if the fix can work on those as well.
 
Many thanks teacher man. Ended up finding that out a bit later. Didn't buy that Mag 2, was a lot rougher than it looked in the pictures and the comp was low. The vendor was v evasive with my questions. A better one will hopefully turn up. Cheers, Matt.
 
I have about 6 hours on my first fix the saw is working perfectly. I've gone ahead and modified a 2nd Bosch module and installed in the second saw. It has spark but I'm not finished putting the saw together. At this point the fix looks good. I'm looking forward to about 20 hours run time. If it works well after 20 hours then I would be confident enough to say: This is a good option to repairing the Bosch.

The repair method described by foggy is what I've been doing with minor minor changes. The soldering is not my strong suit. I messed the second one up but still seems to work (broke off the leg closest to the side but the solder to the farther side seemed to hold and work. The soldering iron I was using was larger than appropriate for electronic soldering. Yippee now I need a new tool, soldering station. Yes, I have one on order. deereguy
 
CONGRATS DEEREGUY!!!!

WE NEED THAT FEEDBACK, BE IT POSITIVE OR NEGATIVE! I used to have a sign on my desk as an engineering manager for younger engineers to focus on. It simply stated "YOU CANNOT ******** PHYSICS!"

The point being that one cannot just claim something ...or at least should not...... works when physics prevents it from working under the conditions described. Yes, there is a fix BUT IT NEEDS FEEDBACK!!!! WHERE ARE ALL THE OTHERS WHO WERE SO ANXIOUS FOR A FIX???

Come guys..... if you have failed ignitions, try the fix and report back. It the thing fails in the long run, the problem should then be re-examined!

I'm waiting on a pair of the MKP 378 Capacitors, the first one will be going in to a 056 magnum that has a failed SEM ignition, the saw will be fitted out with a complete Bosch ignition from a 056 Super.
 
For what its worth--- I have over 10 hours operating my modified ignition. NO problems with anything! My ignition fix worked flawlessly and the saw did get HOT with our weather being what it is.

Does anyone have an updated eBay link to this part? I can't find the 10pack of this part anymore. Was gonna buy some to put away just in case.
 
I looked, the part is no longer for sale on EBay. There is a comparable part but the guy is selling a bag of 80 pieces for $79. There is another part that should work. It is not pulse rated so it might heat up but I really think you should give it a try.

The cost is about $3 for 10 pieces plus about $2 for shipping.

Don't screw around.........ORDER IT!
