revere cdi unit wanted that's faulty

[Steve O'Conner]

Just wondered if anybody had a old CDI unit they could donate to see if they can be repaired as I'm sure they will become hard to find in the near future and there are no pattern suppliers of this unit.

Well..... I have one lying about somewhere.
It's the one that turned out to be the problem here: www.stoeretassen.nl/My_NTV650/Ontsteking/Ignition.htm

I'm willing to donate it for a good cause. But I'm not very keen on paying the price for sending it to the UK.

BTW, otterparts.nl/still have one or two good second hand ones:

Thanks for the offer if I can't find one here in the uk I don't mind paying postage. Has anybody any experience of repairing these units ?

Are they `potted`? Can they be got into would be my first question.

[Steve O'Conner]

Not sure as never looked inside one but even if potted it may be possible to remove the potting compound. There does seem to be a good supply of these units secondhand but that might not always be the case.

I tried to fix mine. This is what they look like on the inside:





As I couldn't find the problem, I replaced it with a good second-hand one.
See my site for the whole story.

Really good to see inside the unit. Because there are two identical coil driver electronics inside fault finding should be fairly easy. I used to work within the electronics industry repairing faulty obsolete circuits boards so I might be able to repair these units. Many thanks for the help so far.

And just an anti vibration and moisture / corrosion sealing resin too. Yes interesting to see inside a unit.

Hi Steve
I think my CDI may be faulty - did you have any luck deciding whether they are repairable?

Hi russ, I haven't had a look at one but I've done a few others from other manufacturers. If your stuck I'll gladly take a look at it.

Cheers
