Certainly sounds like a short somewhere, hopefully not too difficult to trace.
If you stick your location in your profile it will help - maybe there is another member nearby who could have a look if necessary.

Any how will try the continuity test and if that fails try to fix the "BRAND NEW SWITCH" tonight. I will post some photos later if all fails.

Having read a lot of posts about parts for our bikes seems that quite a lot are substandard.

Thanks for advice

I think if there is a genuine manufacturing fault DS will be receptive. If not then we can take it up with them as a 'group'. We have done it before, me being 'piggy-in-the' middle' for it and getting flak from other members  ;D ;D ;D, who don't like him  :D....  but no worries I am Yorkshire thick -skinned trough and through!! Seriously though if it's faultly from the off, don't let it drop.

Just tested the switch out. Here are the results...Using Gunson Multimeter 1

Set to the 200 scale on the ohms .
Disconnected blk/white wire and black wire from the main harness.
Connected red probe to black wire and black probe to blk/white.
Turned switch to off position, meter reading of zero
Turned switch to on position, meter reading of 00.3
Turned switch to off position, meter reading of zero

So It looks like the switch is okay.
Hopefully I have tested it correctly !
Back to the drawing board. Dam

Those readings say to me the switch is duff! the only position where you should get a reading of zero or very close to it is in the "Run" position, the engine stop positions should be infinity (open circuit)

Just to add a bit of confusion,  I tried Mike the Bikes suggestion earlier.
Black is positive and black/white is the feed to the coils.  When the switch is on then 12V is supplied to the coils,  when the switch is off, then no 12V to the coils.

If you remove the tank, check the black/white on the coils.  It should be 12V
With the switch off, the 12V should disappear.

Measure the 12V with the red meter lead,  and the black meter lead on the battery negative or touching the engine.

The readings are Kill Switch off 0.00, With the kill switch on (run) 10.00.
Does this prove if the switch is good or faulty
