Blinking Warning light

[Troney]

Hey guys. My bike is giving me the blinking warning light. I contacted the PO and he said that it was the kickstand sensor. Is there a way to disable it?

[tweeleft]

Must be a XJ. Not sure maybe jumper the wires at the switch. Which warning light?

[Troney]

The big red one at the top of the cluster. Blinks constantly but I've taken it for a few rides and after a bit it goes solid then sometimes goes out.

I have the same bike with the same problem. The warning light indicates many things. When the light is flashing what words can you read on the display? If its the kkick stand it will say stnd. Battery will be batt. Fuel is fuel. Mine flashes because it does not have the right batttery in it. These have a water level sensor built into the battery. Below the display on the dash there are two buttons left one clears the warning. The right one runs the system thru all it function checks. When you start the bike and the light starts flashing press the left one and the light will stop flashing and stay on press it again and it will go off. Oh it also has a brake warning on the dash its brk. I hope this helps.

Well the tank isn't hpoked up and I think it has a diff battery in it so I'll have to see if it says which one after a clear. Thanks for the info I'll check today.

It is showing Fuel, Brake, and Stand. The tank Should go when I rewire it up. Is there a way to by pass the stand sensor? Why would the brake be on?

[tcoop]

the brake light would come on if it does not sence the correct load (not sure if it also comes on for low brake fluid level or if that is a different sensor). It you have a burnt out light or have LED's installed it will blink. The side stand is able to be bypassed i do not remember if you have to put a jumper on that plug or just disconnect it.

Is there a way to by pass the stand sensor?

Yes, there is. First, an explanation. In the XJ, a side stand sensor was added so you could not drive off with the side stand down. If you put the bike in gear with the side stand down and let out the clutch the engine will quit. (There is a switch in the clutch lever assembly. Note the wires comming out of it.)

To bypass the sensor, which makes the circut think the stand is always in the UP position, you need to:

Remove the seat.
Follow the wire assembly up from the sensor to a connector just behind the fuel tank. Tank does not have to be removed.
Disconnect side stand switch wiring at the connection just behind the fuel tank.
On the bike side connector, all 3 wires have to be connected to each other. I made up a 3-way connector using 1/4 in spade terminals. Can't remember if they are male or female, seem to remember I used female connectors and speaker wire to connect the 3 wires together.
Replace seat.

Keep in mind this disables a safety feature. If you choose to do this mod and injure / kill yourself I am not to be held responsible.

Another approach is to fix the side stand switch. You can remove it, cut around the outside (not through) and remove the top end with its wires. Clean out the switch - it gets pretty dirty - and reassemble using a good epoxy to put the parts back to gether. Reinstall on the bike and give it a try. The switch has been discontinued from Yamaha, by the way.

Hope this helps.

There is a work-around for this.

The write-up mentions a 2K ohm resistor; value is not critical and a 2.2k ohm works just as well.

Mod eliminates the flashing warning light and makes the system think the battery sensor is in place and within limits. This works on many Yamaha models of the early '80s and is not exclusive to the XJ.

It is showing Fuel, Brake, and Stand.

Both XJ master brake cylinders have a float in them. If Brake is showing on your LCD display it normally means one or the other is low on brake fluid. The readout does not tell you which one is low so you probably need to check both.

Again, to eliminate some warning signals, jumping the wires together from those sensors will generally do the trick. I would recommend fixing the underlying problem, though, and jump wires only as a last resort. The XJ's LCD system is generally pretty reliable and only reports problems comming in for the various sensors. Fix the problem, don't kill the messanger...

Thanks for the info guys. Next nice day i'll have to check all of the above.
