Parmakit race ignition 1.0kg

Hello everyone.
I have a problem with my new Parmakit, not firing, the facility is perfect, and it seems that failure of the electronic unit with variable timing [:@] , where I can find new? Must have warranty I think.
Has that ever happened to you? Greetings

may the prob is the connection of the black earth cable----- this has to be a VERY GOOD CONNECTION to Body or better to the ignition itself

 

maybe this helps you out:

The installation is OK. The problem is the electronic unit with variable timing, can I send us this part and change it? The ignition must have warranty or no? I need solutions quickly because is the Vespa of a client
 thank you very much
