On all iABS models (integragred ABS with servos), if the brake switch does not work (no change of state, no click), then you will see exactly the symptoms you have described:John, you are the best, thank you. FYI, all taillights were working so I ordered 2 new anyway and swapped two of the existing while I am waiting to see if it would solve the Red steady on triangle issue. It would come on after about 2-3 miles. Well, I took it for a ride and did not use the rear brake for about 10 miles, no triangle. Applied rear brake and within a mile it was all lit up again. That is why I think it is the switch. I cannot hear any "click" when pushing down on the rear pedal, only the servo whine. The brakes seem fine but I am going to take it apart again. Just installed all Speigler lines, pads all fluids (brake, transmission, rear end, radiator, oil and air/oil/fuel filters) bled all calipers as well as ABS pump. I noticed that the tab on the switch does not disengage the pedal until it is depressed almost fully.
If it appear to be intermittent and the switch mechanical test (or OHMS test) is not conclusive 100%, then you may request a GS911 readout assistance from a forum member in your area.Thanks to both John and John, I appreciate the feedback. I just checked the bike in the garage and without the triangle lit up (usually takes 3-4 miles and use of the back brake) I have both top and bottom brake lights from both pedal and lever activation. I will check it again later when I take it out and the triangle lights back up to see if I still have brake lights at that stage.
If you are just trying to read circuit through the switch it doesn't matter which lead of the multimeter you put on which side of the switch. But if you are across the switch and getting those readings then yes your switch could be bad. Important test for your meter though is before you test the switch test your meter. Put the leads together and make sure you get close to 0 ohms.Hey John, this is Jay. I appreciate all the help you have been offering. Unfortunately I am no electrician (just a wrencher). I have an inexpensive multimeter and set it on 200 ohms, Red connector to VohmmA and black lead to com. With pedal at rest I'm reading around 1.5-2 ohms. However with the pedal depressed it is the same. Bad switch?
See attached photo...Leads together, comes right down to 0 or .1, I'm testing leads at the female side of the switch plug with meter set at lowest ohm setting (200) BTW: I removed the switch now completely and with the bike powered up when depressed manually the brake lights come on as they should and the servos engage. I can also hear the switch "click". When released lights go out and servos disengage. It appears to me that the switch is fine but I do not know why the triangle comes on after a couple of miles when the rear brake is depressed. Everything seems ok.
Yes that is correct operation. The switch is depressed (closed) when the pedal is not pushed and opens when the pedal is pushed. Your bike is acting like it "sees" the closed switch all the time. This could be caused by a shorted wire between the switch and the ABS connector.With the switch removed from the pedal the continuity is exactly as you had described. My perception was backward. With the microswitch, when the contact button on the switch itself is depressed the switch is off. Vice versa when the button is released the switch is on. I am definitely not an electrician.
Thanks for all the help. Still have to figure out why the triangle but I feel the bike is safe to ride.
If that was your measurement at the ABS connector (and confirmed again ) then there is a short somewhere in the harness. I would start at the lower connector on the bike side and start unwrapping the cover looking for crushed wires.Hey John, this is Jay. I appreciate all the help you have been offering.
