Subject: Re: The Death of a CDI Unit


>electrical system, but I think my loved CDI is death.

look at http://www.uni-karlsruhe.de/~Philip.Herzog/motorrad/cti.html
since it is in german, I'll try in english here:

CDI's usually die of an internal bad contact at the backside of the plug.
Replacing them is very expensive (300-600DM), but fixing is easy :-)

Open the black box by milling about 2mm off the backside of the box, just
opposite the plug, so that the hard plastic is gone and you can see the
silicone-type filling. Be careful, don't go to deep! Otherwise you'll
damage the printed card inside. Maybe do it step-by-step.

Remove the filling carefully bit by bit with pliers or a dull knife (its
soft, so it's easy). Now you'll see the soldering points of the printed
card. Re-solder the ones that are opposite the plug.

Now seal the unit again with silicone, but cover the soldering points on
the printed card first with some plastic, since some silicone types contain
acid and in this case you can do the same job again 6 months later.

Take a look at the pictures on my homepage to understand my words :-) and
do it similarly with your CDI. I guess the one of the RD04 looks different
but the basics are the same.

And: no guarantee. Most times it works, sometimes not...


Gruss, Phil
