Black or black/white is the earth, blue and yellow brake and tail light, swap those if it's the other way round

@Calum apart from later 03+ engines, re etc...

Cheers guys, ordered from Performance Lab the other day, will update my build thread/make a new one with progress setting up this ignition and my PWK 32 carburetor on the new DTR engine shortly

Hello, buy yourself a Haynes manual, they are all in there

@DTR-NSR i deffo don’t have that !

Any wireing diagrams or pictures of your work please ?

how do you use both you push the switch for main beam

i would put a multimeter on the wires sounds like its not getting enough power if its dull

@BlueMoto yes I've got one on mine. Works a treat - bit of wiring to do and I made a mounting plate as the one you get with it is a bit naff.

Not a huge job though

Bargain 🙂

@admiral323 just an update on this issue incase it helps anybody else.i spliced the red wire from the ignitech into the brown coming from the ignition and have never had a problem again

@Calum im just putting on a new wire i think, do you have any idea where it should go to?

Probably the switch for the lights as the tail light runs off the battery and the headlight runs of the yellow and black wire from engine, take switch apart and squirt some electrical contact cleaner on the parts or WD40.

@notgotaclue You can download the service manual for free from here;

And well worth the money is a Haynes manual;

Both have lots of tips and troubleshooting guides!!! 😉

can some one with a dtr confirm the fuse is 15 amp?
a photo would be be helpful too

Yeah definitely should be a plug in there. 1 or 2 cables for the starter solenoid (to spin the starter) and then 1 or 2 for power to the rest of the bike

It's only on the RE do mains come on with engine off, but only after you start the engine.
