temp light is tach shift light on a 03 900 M1

I just bought this sled and love it. My only issue which has got me stumped is I have a temp light which acts like a tach shift light.

When I start the sled no temp light then I rev the motor it comes on ( motor still cold) It functions like a 2 or 3K tach shift light.

When I idle it goes back off. The light gets brighter with RPM.


Since I have a speedo and tach both temp lights light up equally.

Its almost like the wiring has a short and the temp light is connected to the tach wire.

I have checked the cooling system and the sled is air bubble free and snow melts on all the right spots.

Since i currently disregard the light it will not warn me if my motor ever does get too hot.

besides discarding the tach and speedo,or removing the bulbs where should I look?

Thanks,

Ian

Found it!!!

My temp sensor is bad. If I disconnect the wire from the temp sensor the light goes out. The light is on all the time, the engine revving just causes the on light to be bright. The light is off only because the power is low at idle.

I am going to replace the sensor and my problem should be solved!!

I replaced the temp sensor and it works like it supposed to ( light off during normal operating temp)

I checked the A arms, the bars are all straight and there is no weld issues I think its the camera and angle I used for the picture. ( a little fish eye distortion?)
