Hall sensor 2005 R1150GSA SE

Out of curiosity, does anybody know whereabouts the wiring is known to fail on these?
The bike has been misbehaving recently. A couple of times it's cut out and been difficult to start again soon after setting off and occasionally stuttered a bit on a run.
In the past couple of years I've replaced the coil sticks and TPS so guessed it was time to change the HES in any event as the bike has done 65k miles.
The new one is fitted but I haven't run the bike yet as I'm waiting for some new fuel disconnects to arrive.......
Anyway I thought I'd look at the old HES wiring to see if I could see a fault and it looks clean, pliable and undamaged.

PS I'm hovering over the bike so tempted to remove the abs and servo while it's accessible. It just grieves me to fix something that 'ain't broke'. I know I'd prefer the braking without it and the weight loss wouldn't go amiss. I suppose it could always be refitted if a new owner wanted it sometime in the future. Just pondering......

In my experience used abs/servo modulators do not like being kept on a shelf unused and fail in a very short time if refitted or bought used and fitted.

Thanks Neil. I remember we discussed this at the time you diagnosed my intermittent TPS fault. The conclusion then was leave it on if it worked! If I could be sure I'd have the bike long term it would be off but who knows......
I'll leave it for now

All back together and running sweet as a nut so far.

I won't fret over where the fault is on the old one

A bike with ABS is in general, inherently safer than one without. So if it ain't broke, don't fix it.

HES wiring - comparison with the failure-prone old style wiring as compared to the later setup with the 'softer' sleeve, which is slightly more resistant to the constant cooking which the HES unit is subject to from the crankcase.

Failure of the wiring normally occurs directly underneath the unit, where you can't see it without removing the plate. It's where the little bracket holds the tiny loom wrapping in place.

Thanks Al.

I had the new style wiring on the sensor which may or not be the original from 2005. I just couldn't find where it might have failed on the one I replaced. Anyway it's much better now with the new one fitted

I will leave the ABS/Servo there for now.....I think. It would have been convenient to remove it while it was all apart especially as I have to replace the gear position switch - see other thread.
