Hello,
The ignition unit will have to be replaced. Repair parts for the EI unit are not available.
I'm really sorry to hear that and I'll consider this information regarding Fuji customer support on my next purchases, for what it's worth.
Anyway, I solved the problem soldering the cable using a steel stick as a bridge and soldering the whole thing. The engine is working fine, no problem or RF leak. It solved the problem with the 5 bucks cable and saved me $160 dollars on a unit I don't need.
Thanks anyway,
Flavio
