I have a 85 TRX 250 and it has no spark! I have replaced CDI coil and spark plug. I took off the Left Hand side cover and oil came out. Thanks in advance
Well having oil come out is a good thing - motor will lock up without it.I have a 85 TRX 250 and it has no spark! I have replaced CDI coil and spark plug. I took off the Left Hand side cover and oil came out. Thanks in advance
The oil is coming out if the left hand cover that has the stator and the pickup coils is that normal?Well having oil come out is a good thing - motor will lock up without it.
First step to getting spark; Do you have 12v on the blk/wht wire at the CDI box?
So if I have replaced the cdi coil and spark plug what would the problem most likely beIt is normal - the alternator and ignition pulse coil run in engine oil to aid cooling the stator windings.
No voltage on the blk/wht wire at the CDI unit or a faulty ground on the green wireSo if I have replaced the cdi coil and spark plug what would the problem most likely be
Where would the green ground be at?No voltage on the blk/wht wire at the CDI unit or a faulty ground on the green wire
Good question - I suppose it will be somewhere on the frame - the service manuals are not that specific, they expect you to use your or someone else's eyes to see where they are attached - many times they ground at the coil.Where would the green ground be at?

What reading should I get from the blk/wht wireThe coil that goes to the spark plug
When I took of all the plastics I found the ground and it seems to be fully on there.There is no reading on the blk/wht wire - blk/wht is connected to ground to kill the engine
Curious - where did you get a CDI unit since they are no longer available from Honda? How do you know the old CDI was bad?
Check the CDI charge coil for continuity and peak voltage - resistance should be 50-200 ohms if it is a Nippon Denso ignition or 250-400 if it is a Mitsuba ignition (you can tell by checking the CDI unit (it will have an ND or Mitsuba marking) - peak voltage is usually about 45 volts (checked on the DC scale of a peak voltage meter).
If that's all good then the CDI unit is at fault - make sure the CDI box you got is an AC and not a DC unit. Who ever sold it to you will know.
