laverda 1200ts mirage, problem on high revs

ok, thanks, for sure  I will replace the sparkplugs, but... for sure this is not a reason for foulty ignition box ? 
should I buy even single cylinder ignition coil the same as I have double one, Dyna brand ? can a coil damage the eletctronic Ignition? 
Maybe I had a bad contact in fusebox, from where 12v input goes to ignition box, and this burned it..  IM happy for any suggestion.

thanks
 
I've no idea what Sasche do to protect the output in their black box in the case of faulty coil. However, I suspect that as you have a good spark on two cylinders then the box is OK.

You may have a faulty coil - you don't need to buy another Dyna coil, but it would be sensible to try a different coil with 2-5 ohm impedance.

Sasche do have a history of trigger plates going faulty. Do both LEDs flash when the engine is running?

A bad electrical contact wouldn't cause the ignition to be damaged.  But it can prevent the ignition from working correctly.

 
yes As I described, to test sprak plugs and coils , I tried to change outputs on ignition box. Output 1 on box is only working. 10 is dead. Double and single coil and all three sparks are working if they get signal. I jave sent the ignition box to germany again, hope that it can be fixed as previous time.

ROB:
the led on plate is working when pistons in TDC position, I didnt check when engine running. I also checked if signals is coming from the plate to the box trought tat small cables. So I changed them between them, and signal came from both 180 degres sensors. Just output 10 on the box is not working in any way.

How many of you have this sachse ignition kit on your bikes? Am I only one to have the fault already two times?is
 
I?ve got a Sachse too, but only for 10,000km - so far no problem. I?ll be interested to know what Sachse say (if anything)

P.S. I suggested changing the plugs because it?s the easiest thing, and you hadn?t tried it yet. I didn?t understand that you had changed the outputs to prove the coils and plugs  :D

I agree that the box must be faulty with the additional information and symptoms you describe.

Me too - misread (or missed) that you checked by crossing over parts - a dud box for sure. A new one rather than another repair would be the best outcome.
