2nd gen Ignition Coil issues..

[Winddancer]

Hi All

 

I seem to be having a major issue with coils..

After test my new LA Chopper exhaust, decided I needed to tone them down a little so I put back on the old exhaust..at that point it started sounding a little funny, so I checked the header pipes and found a dead cylinder, so I checked carbs and cleaned them, still no luck.. check checked the spark nada.. nothing.. swapped wires to right side good coil and got a good spark, ordered another coil of ebay, swapped them.. all's good, until now, a few days later, going to work on exhaust again.. and again it sounds funny.

do my header pipe test.. now the right rear is dead.. checked plugs very weak spark, ran a continuity check on both right and left.. numbers are the same.

tested with different plugs, swapped ends from old one, cut off a section to get fresh new contact, and just about everything I could think of, still just have aweak spark..

does any one know what's going on and why this is happing..

do I have yet another bad coil, or is there another place I should be looking at?

This has me lost, I have never yet in my motorcycle life had a bad coil,

and now I have 2 in 2 weeks..

 

Thanks for any help you can give

Yes, unfortunately the coils do fail, but I think you are the first to have 2 fail in 2 weeks...
