DT125R FORUM

I have tried another CDI still no luck. No servo cycle and no spark. I have tried three different stators and same result.
Because the replacement bits I .trying are second hand I have now way of knowing if they are ok. Is there a way to work through the bots one by one. For example can I connect the servo to the battery somehow to see if it works? I can turn it by hand so it's not seized. I don't understand why servo and coil not working. Please help.

Many thanks for the response. The engine and frame numbers don't match so you could be right. I have had lots of challenges with the wiring since I bought the bike. I do have that Haynes manual but it doesn't show the wiring to the servo.

Good morning all. I have a 1989 DTR125.
While riding the other day it started running rough then cut out.
Now when I turn on the ignition the servo doesn't do a clean cycle also when I kick the bike over I get no spark.
I have tried a second used CDI same result but second CDI may also be faulty.
I have measured the brown wire into the CDI and that is send 12v into the unit when ignition is on.
None of the other wires on the CDI send power out.
I would expect to see 12v leaving the CDI to the servo but I don't know which is the power line to the servo it is missing from the Haynes circuit diagrams. The servo has 5 wires to it. A four block connector and a separate single white and red wire.
All help much appreciated.
