Oil temp light not working

[sugarray]

I have a 2006 Rancher AT I have been getting ready to ride. It was part of an estate sale my FIL purchased. It had been wrecked and then not ridden for several years. I have a local guy that is helping, but he’s working to get his shop open so I’m trying to leave him be as much as I can.

Last thing I have is when the key is turned on the oil temp light does not light up. I haven’t ridden it enough to know if the fan comes in when riding, but I can ground the wire and the light and fan come on. I have replaced the sensor and that sub harness, but this didn’t fix it. I have replaced the switch harness as well. I cleaned and dielectric greased the ground.

It runs, shifts well.

Anyone have any ideas of how to trouble shoot this? How to fix this?

Any and all ideas greatly appreciated.

Which wire are you grounding? Have you pulled up a wiring schematic? On my old honda atv I believe 'the oil light came on when the key was on then shuts off once started. Is that correct? Test the sensor and see if it is an always open or closed switch. Then we can sort out the ground/power issue.

I grounded the wire that attaches to the oil sensor.

Yes, light should come on for a few secs when the key is turned on.

How do I test if the sensor is always open or closed?

I have looked at the harness layout, but not a wiring diagram. Not sure where to find the wiring diagram. I’m trying to get the service manual from Helm.

Just test for continuity between the 2 posts of the sensor. Using a multi meter is the easiest way. If you don't have one you can get a cheap one for $10 that will do this test. Turn the knob to the setting with the sound wave. When you touch the 2 prongs together it will beep. Touch a prong on each post of the sensor. If it beeps its closed if it doesn't beep its open.

Well, crap. I’ll have to drain the oil then. Otherwise oil will shoot all over when I take it out. Ok

No you can leave it installed as long as you can get the wires from the mulitmeter to the two posts of the sensor.

Hmmm, ok, I’ll look at it tomorrow night. I don’t remember it having 2 posts. It has a round fitting that slides over then end of the probe. Maybe the center and the side?

 

[Cuoutdoors]

yea if it just has one post than the body of it is the ground.

What did you figure out here?

When I touch positive the end or side of the tip where the connection is made and then black to the “nut” or base of the probe, I get no movement when on the Ohm setting

 

[Cuoutdoors]

Is there continuity?

No idea what you are asking

 

[sugarray]

This is my meter

 

[sugarray]

Here is the sensor

 

[sugarray]

I turned the meter to the RX10 setting and put the tip of the + wire on the tip and black side of the sensor, I then put the - wire on the nut or engine. I did not get movement of the needle.

If I do the same connections on the RX1K setting the needle moves to about 15 ohms

Put the meter on RX10
Touch leads together, use the adjustment on the left side of meter to make the needle be positioned at the right hand side of the meter scale

 

[sugarray]

I did that before I started

It goes to 0

 

[Tramguage1]

Now the meter is zeroed.
Do Sam e procedure when you switch to RX1 scale

 

[Tramguage1]

Ok then I dont think 15 ohms is correct. I would expect 1k ohms or more.

 

[sugarray]

Ok, I had to turn the dial down to get it off the peg to 0 on RX1K
