I noticed my amber ABS lamp is staying on most of the time, by far.

At least 95% of the time that I am riding it's on.  Once in a while, it will not be on after I ride a few feet, but usually will be on within a mile. But most of the time it's on no matter what I do.

Bike is  a 2017 Zero SR W/pwr tank, has around 3000 miles on it.

What is the most likely cause for my ABS lamp to be stuck  on while riding?

It's my understanding that the ABS indicator will light if the system isn't functioning because of a malfunction,  if disabled by the rider,  or if the bike is operated in a way that causes a large wheel speed difference. Low tire pressure? Blown fuse? Chaffed wires?

Fuse first. Just see if it's tight in the red holder. Then I would inspect the wires at pinch points and around the sensors at the tone ring on the wheels.

In my case it was clearer:

I have already checked the two ABS fuses and  made sure the  wires going to them and their sockets are okay.


I just now took a quick  look around the two ABS wheel sensors as well as the exposed wires from them, and I notice no obvious problems with such.

Tire pressure also okay. I have a TPMS in the GPS I have on the bike.

One thing I have not checked is the ABS module connections. I assume there is such a module  in the bike somewhere. Where is it located?

It's in the forward part of the frame. You might be able to see the brake lines by peeking under the front corners of the tank cowling. It might be hard to check much with the PowerTank installed.

Thanks for the info. Looks like I will have to tear into the bike to find the problem.

Take it to a dealer for warranty?

Dealer in Reno pulled out and does not anymore have access to Zero Motorcycles diagnostic tools, next nearest would be Elk Grove (southern Sacramento CA).

I bought the SR in Elk Grove and I keep it at my house in Auburn, CA.   I  have my DS here in Reno and it has no problems.

But I try to avoid dealers for repairs even when the bike is in warranty. I would rather just fix it myself, even at my own cost.  Besides, three  of my nine bikes don't have ABS anyway--And I ride them as often as my other ICE bikes. It's something I can live without, but I will still fix it someday. But I have not felt like trying to take the bike apart in the 100°F Auburn heat. I would rather ride the SR to Rollins Lake and go for a swim, which I often do in the heat when I am staying in Auburn.  BTW, it's also been around 100°F here in Reno just about every day.

BTW, I had no idea that the Reno Indian Shop gave up on Zero. Is that because the sales were low?  Perhaps somebody else in Reno will take over  Zeros one of these days.

Today, since it's not so hot here, I decided to take a better look at my ABS problem of the ABS light being stuck on.

The only thing I found that is a bit strange are the resistance measurements toward the wheel sensors.

From under the seat, at the two wire ABS connector towards the rear ABS sensor, I get a resistance measurement of 48.5 KΩ.

From the connector behind the headlamp for the front ABS sensor, I get an infinite Ω reading.

I don't know if this means anything or not, but I would have expected both readings to be the same.

What should I expect?  Turning the wheels make no difference in these resistance readings.

Infinite resistance = open circuit. Maybe a broken wire inside of insulation that appears intact.

I will compare those SR ABS sensor ohm readings with my DS ZF 6.5 here in Reno. If I find both on this bike to be 48.5K, I will then assume my front SR sensor , or wires to it are really open.

I will post here what I find. I will probably check it tonight. The DS has no ABS problems, it works as it should.
