Yes--- you should feel real, real bad but only if you hurt your back carrying them to your truck : - )
Better do it before word gets out about a fix!

Maico490.. I bought 10 winging there way to the U.K..
Just a case of waiting for them to turn up.

I just captured all the pix and pertinant text info into seperate .jpeg's and saved to disk to make sure i have a handy referance on this subject that wont dissapear someday like so much that has been lost on this forum.
i hope the situation on the " other " wires on the unit is made more clear when i actually have a unit in hand.

There are not many "other" wires to make things complicated. There are two yellow wires displayed that attach to two terminals on a new capacitor.... not polarized. On the other ends of the yellow wires has one attached to a grounding lug while the other is soldered as displayed. The black wire is a replacement for the existing wire whose insulation is rotted away. Oh the large wire in the ignition is the spark plug wire.
Your worries about lost information is true. This free repair instruction should be made a sticky but I will leave that to the moderators.

Tnx for clearing that up,,been so long since i seen one needed clarification.
even as a sticky the info could be lost,,as happened not to long ago
where abouts south of my border you at ??
I did get the capacitors through e-bay and have one saw coming in for the fix ( after the crops are in the ground ). Have another 056 setting here that has bad coil but it is not the Bosch set up.

ok,curiouse,,,I'm about and hour or so north of Boston.
Weeell............your's can be number three. Do the fix on yours and get back to us with the results. And be aware of the insulation failure on the shut off wire. Either add new insulation such as shrink wrap over the wire or cut it at the ignition and splice a replacement wire to the cut.
can't do the fix on mine. Axlr8 has about 2.5-3 of these things I sent him and he's making 1x 056magII for me. He's real eager to run a 056magII so he wanted to get my points figured out. I was just wanting the points b/c I didn't want to mess with failing electronic parts in the future. I think some assumptions were made about parts failing on these due to moisture and heat. However, it seems you have a good solution to a long term problem. Now we just have to find a company willing to make the special sized clutch side bearing and seal for us. If they blow out... GOOD LUCK finding a cheap NOS replacement for them! I was lucky enough to find the some modestly priced parts to round out 90%-95% of that magII Nich (axlr8) has.
I'm sure he will turn up over here in the next day or so... Then he can run the fix on my saw and send it home!
PS: foggy... I think i understand the wire routing you used but a side pic or two of where the 3 wires are running into the "coil" would probably be better. Some of us just turn wrenches and don't know the proper terms for all the electrical pieces you were talking about unless you have a pic that has lables pointing to the parts... Good to see we have someone good with electronic stuff around now!!!
PSS: I'm with Neal... crack open one of those Dolmar 6400-7900 coils and tell us how to dissable the "electronic limiter" that keeps the rpm band under 13,000(?need a number check?) RPM. PITA to tune a limited saw when it's bumping the limiter at WOT. I've got a dcs6401 I can send you if you want to take a shot at it!!!!

You make a good point regarding a side picture. I'll try to do that a little later when I have my camera with me. But maybe a few words will help.
My pictures show two yellow wires. One wire is clearly visible where it was soldered and later covered with hot glue. The other yellow wire has a wire connector crimped onto it and is attached under one of the screws holding a coil to the assembly. That wire provides a ground connection. I placed it under the screw to keep the electrical path length short.
The black wire is the wire that goes to the shut off switch. But your right, another picture showing how its routed might help. I have a "gutted" ignition that I can use later to take some pictures for you.
I cannot help you with your Dolmar problem. I don't have a saw [ and no--- please don't send one to me :- ) ] and I really don't have the time to dig into the problem. And again---- I will stop correcting those of you who call the failure a "coil" problem. There is really no need for anybody to know what the individual components are called.

awe shucks!
where is the dislike button when you need iti would love to do this to nates saw, but all i have for electronic ignitions are SEM that are untested. I threw 8-9 bosch units in the garbage cause they didnt work last fall..

Does anyone know if the husky 2100-2101 Bosch ignition is the same as this one repair wise?

What other coils would this type of repair work on? What brand is the "dogleg" on an 064?
My guess is that if the ignition is made by Bosch, and if it looks the same, it probably is the same. So if it was me that owned a failed husky, I would try the repair. Once you have dug out the potting material and see if the internal PC board has the same copper run that needs to be cut for the repair, the detailed repair most likely will work. Now of course, it will be up to you to find a mountable location for the new capacitor which is not a big deal.
I do believe some of the huskies do use this ignition.

Joe, Sweet.... Your fix worked well. I mounted the capacitor in the same location that you did. Although, I used a couple ties to anchor the capacitor. It started after a couple of pulls. Didn't seem to be any timing issues. I'm planning on running this saw this afternoon for a couple of hours. rick in Shelton,wa.
