Title: Quick question.. Switch IDs ?
Post by: KCinSB on October 24, 2021, 11:14:59 AM
It’s getting colder, and I have forgotten which switch is which. Is the far left switch the Heated grips? And that far right switch is the ABS? If so, I guess the ABS is supposed to have an indicator lamp in it. Hasn’t been ther on my watch,…..  +/-15 years. For that matter, the Left has no light working either.

The heated grip switch will have three positions, a center off and two positions for high and low heat.

The ABS switch has two positions, an off position and a momentary on position that doesn't stay down when you take your finger off of it.

The other commonly found switch is for the hazard flashers.  It is a two position switch, off and on.

Got it! Thanks! Might try and get the lamps working at some point…..

A light in the switch itself was not standard equipment; it may have been a feature in the Presidential, Prime ministerial, and El Jéfe models, but there is an accommodation for one.

Here's the stock layout according to the K1100 Riders Manual downloadable from this site.

Thank You! Maybe its working as it should then, with no switch internal indicator lights.

Early K75s and K100s did have a lamp in the hazard switch that flashed with the hazards.  ABS switches never had a lamp.

It is possible to retrofit LEDs into the switches though:

Heated grip switch: The up position is the high setting and the down position is the low setting.  If you use the low setting for an extended period of time then it can cause a short and in rare instances a FIRE under the tank.  This is because the low setting uses a resistive wire to lower the voltage to the grips.  That resistive wire generates heat and if left on for an extended period then it can get hot enough to melt the wire's insulation.

Yeah,  that portion of the K-bike's wiring design was outsourced to Lucas Industries by BMW.   :laughing4-giggles:

I believe the Lucas technical term for the heated grip wiring is a smoke release valve.
