HEllo!

I have problems again. Seems that Electronik-sachse Ignition is faulty.  Talking about Laverda 1200TS Mirage, year 82.

All hapened really strange. Last week  I had a ride, and when I came home, stopped the engine and trying to run it again, it didn't start. Refiled batter,, and it started.
I checked the voltege, and alternater filled about 13,5 v at 2000rpm.  Maybe I had to long ride with long lights, dont know. I also tried to change a spare regulator, but same voltage.
OK, This is not the major problem now.

When in disatached battery, connect cables, whatever, looks that i made some electric short contact, and burn the ignition. This is only possible option from my point of view.
I put spare park plugson cables, to see the spark, and turned the engine. Ignition is working(giving output signal) only for single Coil (output 1 on ignition), but not for Double Coil (output 10)

If I try to change output, between connector 1 and 10, means , to change signal to Coils, again, only output 1 is working.  Both coil are working, giving spark, if they get signal.
I tried  to change even inputs (small cables ) comming  form optical sensors on crank, and seems that both works. I tried all combinatins.  Output 10 on blaxk ignition box, never give signal.

Maybe is important, i noticed also that Dual coil (new, Dyna brand) was kinda hot. lets say 50 degrees. Is this normal? Because single coil isnt hot.

Im so angry, because we have a Laverda meeting in Slovenia near me in a week, and I can't be part of it.

What is naw to do? any suggestions?  I heard that this mister, who produced this boxes is not more alive. Is this Ignition fixable?  who would be able to repair it?
Tanks for any advices.

Thanks, I wrote mail to them, but no answer yet.

Did anybody had problems with this Ignitions already?  Can I try to give to some local electrical guy, to change some trannsistor? Something...

thanks


 
Update.
They, the father and son, who bought the company from Volker's wife,  are answering the phone, and speak fluent english. I have sent the ignition to Germay, they will see if there is somehing to do. If not, I will have to buy another set.

thanks
 
Hi,

I sent a 'Volker' unit back to the new owners - turned out to be the ignition back plate not the black box. Just normal wear and tear no one's fault.

All sorted efficiently and inexpensive.

I'll buy from them again.

Nick :-)
