No speedo after absectomy
Posted: Sun Jun 02, 2013 9:45 am
Have just done the absectomy as ABS failure(residual braking on rear brake circuit) followed the instructions regarding the electrics from ukgser as below
1) Remove the blue ABS relay from the fusebox. This will extinguish the 'Brake Failure' warning light on the dash and as a bonus can be used to operate the brake light !! (no need for new switches as in other methods )
2) Strip back the sheathing from the ABS multi pin connector - identify wires and connect as follows
a) Grey/White wire (tail light feed) Grey/Black wire (12v feed) cut both and join together - thats your tail light sorted.
b) White/Yellow wire (front brake switch) and Yellow/Green wire (rear brake switch). Cut these two wires and join them to link brake switches
Now the wiring to the redundant 4 pin ABS relay
c) Pin 1 - Connect white/blue wire
d) Pin 2 - connect the THIN solid brown wire in the loom to provide a ground ( careful here - there are several brown wires c/w coloured traces and a Thick brown wire)
e) Pin 3 - Find the Yellow/Black wire and the solid green wire. Cut and connect these together and then to pin 3 of the relay
f) Pin 4 - Connect grey/yellow (tail light feed) to this pin
That all there is to it - you now have working brakes and lights.
All appears to be ok and have brake lights front/rear and rear lights with headlight on but speedo is not registering.Speedo was ok prior to absectomy -perhaps there is an electrical connection that is required on r1100s ? seems a bit of a coincidence that the speedo/sensor has packed up , any thoughts/advise welcome.
