Its been a while since i pulled the Mk3 apart, didnt take enough photo's and cant remember or find a "logical" point close to where these two wire terminate (LH Side).. One is absolutely obvious with the factory fittings. But where ive attached the red wire to the chain gaurd securing bolt just dont look or seem right.. there seems no other termination point close to accomadate the red wire... Only place that would be a good fit would be under the "brass" fitting (earth point)... Therefore are these two wires terminated on the heat sink.. Anybody know the correct point of contact




Earthing Point
 
The correct point would be under the zener diode. [brass fitting]


Correction,
After looking at an unmolested MK3 I see the ground is under a long bolt w/nut which is used for the rear footpeg mounting.

I'm not sure about this, the diode depends on good contact with the aluminum as a heat sink and a copper ring terminal would defeat this purpose. The left foot peg mount on my MK3 is secured with two studs and nuts at the front and one longer bolt at the rear. This bolt is long enough after being tightened to the 'Z' plate, to secure the ground wire's ring terminal with a nut on the inside I'm pretty sure it was always like this.
 
Thanks for the replies,, ON recollection the diodes had a compound/putty type adhesion substance on them when i stipped down, thats why i didnt choose that point straight off. When i replace alloy brace and fitted the studs i used 3 equal length for the foot peg support.. Maybe one was longer but didnt notice. I dont have many nuts bolts etc without an allocated place to be, and definately no stud/s left.. I did package stuff(38 bags) on teardown to eliminate this sort of thing, but thats the way it is..

I will use that third bolt on the foot peg support arm as a home for the wire ... I will find/make/source a longer stud but wait the obligitory week before buying because the "shed fairys" might put it back in my assortment of bits..

Yes, but the rear footrest "bolt" [17] goes outside the Z plate with the earth ring terminal under the nut on the inside.

The diagram clearly show 17 as a bolt, and 2 studs to secure footrest.. To me, the bolt is posistioned top front of footrest, and relooking at situ there is no room to fit a protuding bolt/washer etc, ??? the rear most stud/bolt of the 3 is the most accessable.. ... #17 bolt in diagram is strange?? why would they fit 2 studs and one bolt, particularly top/front location of the three anchor points...... I will use the rear most point!!

The parts drawing is slightly misleading.

The "bolt" [17] 061246 is actually a fully threaded "hexagon-head screw" (or "set screw", note the AN part description = "HEX.SCREW - FOOTREST MOUNTING" not "BOLT").


All three L/H Z-plate footrest mounting holes are threaded, however, fitting the Hex. screw in either of the other two (stud) positions would indeed make the job of removing the L/H footrest arm even more difficult than it already is, as the ring terminal retaining nut on the Hex.screw does have to be removed before the Hex.screw can be unscrewed in order to release the footrest so the rear position is the most accessible. :)
