Hi,all

I have own Aprilia Climber 240. Also lost the spark , checked the plug, took the flywheel off and cleaned everyparts, coil and burn-in. Eventually I made a conclusion that doesnt work the condenser (ECU).

I have one question.

Please advice me how to remove the condenser that silicon bounded in the ECU box (CDI).. 

Any suggestions ?

Basically, you can't, all the components are in the resin and will be damaged on removal and you won't be able to get replacements anyway. I think a guaranteed second hand one is the best option

If your sure it's dead and you have time on your hands, you can dissolve some potting compounds. Worth trying if you have nothing to loose.

Dissolving depends on the type etc, Try google search on 'dissolve potting compound'. But then unless you know what you're looking for or can test the components you could be on a road to nowhere.

Worth a try if all else fails, but as mentioned above swapping it out is probably going to be the way forward.

Hi all

I’m so sorry that I can’t reply at once.

Thank you foy some good advices and I was overwhelmed with several advices.

Then My ECU was mounted to other Aprilia Climber so that I can check again my ECU unit.F

It was good working order! 

Next step, I measured zero-power ohmic value of the exciter coil (generator).

I found out some trouble and slightly malfunction. My exciter coil 320Ω (common 800Ω).

I could fix my generator by replace the exciter coil.

Thank’s a lot !
