HELP I HAVE A SPARK WHEN IGNITION IS OFF BUT NOT WHEN ON



  • PLEASE HELP

    Hi all I have a dtr 125 I am currently baffled by what is happening I have been over and over the wiring diagram and am 99.9%sure it's exactly how it should be however when the key is off I'm getting a spark when the key is turned on the power valve boots up but I lose my spark somebody had tried to steal the bike in the past and all the wires had been cut I have had 3 of these bikes in the past re wired all 3 off them myself but this one is stressing me right out how could I possibly have a spark with the ignition unplugged I have also noticed that when I disconnect the battery I can get a spark with the key on or off but obviously this means the cdi is getting no power and the power valve will not operate and also the bike wouldn't cut out with the key being turned off any help is very much appreciated thanks in advance
