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.

Electrics Problem Maybe CDI -
Electrics Problem Maybe CDIGood 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.
