Last week I took my K75s for its MOT yearly test, my ABS has been flashing from the second day I bought the bike it last summer. The testing examiner refused to test it as " any warning light on the dash should extinguish as per manufactures specification" I asked what would happen if I removed the bulb the answer was the same. So I contacted another garage and he asked if it could be turned off ? "why yes the switch is on the dash" I answered . Okay bring it over, so I disconnected the relays and bingo one MOT.
I have found the problem the rear ABS sensor has died, I have cleaned it and the wheel ring and re set the gap on the sensor but it is dead.
 I don't want to pay the £120 wanted for a new pattern part as I have seen loads on eBay for the oil heads at £20 to £30, but doubt they are the same as the older K bike sensors. Has anyone here in the UK got a rear wheel ABS sensor that is working and they would like to sell if so please could you let me know as I would like to return the bike to full spec.
Many thanks.
Don't wait now is the time, enjoy.

I have a front sensor off a 1993 K1100LT but I think the sensors are different between front and back. Tried EBay or David Walker (posted above) ?

Hello,

I have rear ABS sensors....Trouble is they are in the rear calipers and I don't remove them for fear of destroying them.

The sensors front & rear are different although the only (AFAIK) difference is in the length of the cables! The front sensor changed on the K1100 in 1993 as well just to confuse matters with a different plug.

I have known a couple of cases where users have grafted the correct plug onto the sensor with success - The cable is (my best description) a bit like a TV aerial co-axial cable and a join is apparently possible but I have not tried it yet.

Not sure how helpful that is?

Best regards,

David

As mentioned here earlier, I had an issue with the rear sensor and the cable, and as David mentioned above was able splice around the bad section. If I remember right, it's a cable with a braided shield. You have to take to keep the shield and conductor isolated, but splicing is easy enough if you can locate the break with a test light or multimeter. There was more than enough slack in the cable to cover the splice.

Hi guys, thanks for the heads up I contacted the two usual UK suppliers which is where the £120 figure came from  :eek:
My multi meter test showed the code for the rear wheel sensor, so I did the usual stuff, cleaned the pick up wheel ring and gently cleaned the sensor and re- set the gap. I checked the sensor wire up to the under frame connector got fed up with it and went for a ride instead. When I got home I put the bike to bed and whilst tucking it in and kissing it good night noticed I had not secured the sensor wire into its swing arm clip firmly enough. The result was that it fell out and rubbed against the rear tyre which cut it through. Dooh!
So I never did find out if it was the sensor that went bad or the sensor wire that went AWOL, best solution is replace the whole sensor and wire up to the frame connector.

David (hi Dave) mentioned having a whole rear sensor, wire and calliper as a complete item and I can understand why he would not want to disconnect the sensor. I have just (this time) managed to get the bike MOTd and the tester commented on how good the brakes worked so do not want to disturb the calliper and bleed the system just yet. But let me know how much you would want for all of the above Dave.
Many Thanks
Mac.

Hello,

I have 4 at the moment complete calliper and sender all in good shape. I list them at £20 so drop the fees of I would post within the UK for £17.50. Anywhere else in the world for cost less £2.50. Send me an email or PM if you fancy one and I will sort the best one out. PayPal is best (Gift much appreciated of course!)

Oddly front callipers sell very quickly but very rare to shift a rear one. However at that price a good opportunity to strip & rebuild into a perfect example!
