My baby let me down today...ignition problems?

[msbuck]

Can't say I'm a fanatic, but when I can I'll do it.  Talked to the Service Manager about it today and his opinion was the reliabilty wasn't much different and with such a small price difference it makes sense to use the stock.  Don't have to worry about incompatible parts (mixing Bosch with other componants.)  Graham had a problem with the Bosch system on his Porsche years ago and his mechanic told him the problem was his aftermarket componants.  He went back to full Bosch and never had any more problems.  Not saying this is the case with ours, but it's just one less thing to put in the mix.  As I said, I had good reliable service out of my stock unit for 23 years and over 60k.

Glad I saw this one. . .took a look at my coil, and I'm honestly surprised it hasn't failed me yet. Pictures soon, and it looks like I'll be ordering a Dyna tomorrow.

Aïda, did you ask your service mangler about the ignition module?  I know I read somewhere (maybe on boxerworks) where somebody went to the "upgraded" coil and the parts guy told him he was supposed to change the module as well.    Did you say that yours was already the "upgraded" coil?  If so, then I guess it would not apply in your case...  The only reason I could think of for this would be if the new coil had a different resistance.  When you get your new coil please put a meter across the primary and measure the resistance - just to satisfy my curiosity!

Don't think I asked that question.  I should get the coil next week when I go back to work.  I'll ask him then and I'll be glad to ...

I have the original type now, not the upgraded.  So we'll see...


Mumford,
Mine didn't give me a lick of trouble till I was in the rain.  I think I would be ok as long as I didn't ride in the rain, but you never know.  I was quite suprised by the failure...I just knew it had to be the rain.

OK, I'm a bit slow here, but we have the new BMW ignition coil installed and WHAT A DIFFERENCE!!    I guess I didn't realize how hard starting the bike was until it's not anymore.  It was never hard to start, just didn't usually start the first push of the button, but it does now.  

We asked the Service manager about the ignition module and he had never heard of having to upgrade it.  He even did some research and couldn't find a different module available (BMW wise).  I did start out with the original non-upgraded coil and now I have the upgraded coil.  As far as the resistance across the primary coil, my first coil had about 1.6 ohms while the new one has about .8 ohms.      Does this sound right, Justin?  I'm not real familiar with all the terminology trying to test this stuff and got a little confused about it all.   :-/

Put the Dyna in a couple days ago. . .all of a sudden i have instant starts.  . .damp, cold, warm, hot, all instant starts. . .

Chalk another up for the good guys!!!   [smiley=1drink.gif]  I love it when a plan comes together...  

Aïda, I guess that the parts guy mentioned in the other post (I think it was boxerworks) just needed to pad his sales for that day.  The only thing that makes me wonder is the primary ohms, .75 seems a bit low (but I have no "new" old style coil to check) so maybe the "new and improved" coil has a lower primary resistence.  This may be why the parts goober suggested the module be changed as well...
