DT250MX Electrical problem

External Since: Feb 09, 2005 Posts: 2

Hi all,

Not sure this is the correct forum but here goes.

I don't suppose anyone out there knows how I can check out if there is a
problem with my CDI unit on my '80 250MX. A week ago I used the kill switch
to cut the engine and - no more sparks. Unfortunately that is how it has
stayed since. I have checked out everything I can think of, the bike was
rebuilt recently and the wiring is in good condition. I have checked for
breaks and bad earths but it all seems fine. The rectifier, regulator and
magneto check out OK so I am left with the CDI (as I see it - suggestions
welcome). I only have a Clymer manual which says 'get the CDI unit checked
out by a main dealer' but I don't think any of my local 'pile em high, sell
em cheap' dealers are worth a visit.

The CDI has 6 wires coming out - Orange, Black, Black/White, White/Red,
Brown and another unused black. Does anyone know how I can check out the
CDI unit?

Any advice appreciated, Paulie
