Hello, I know that there are alot of questions about the ever growing concern of the oil light and temp light coming on, and I can safely say that i myself posted topics on the question, however... I have been doin some thinking on the question, so here it is, sorta my theory don't no if its right. After my oil light coming on a couple of times i decided to install a toggle switch to control the fan. Hooking the wires from the toggle to the 2 wires that would normally go to the theromstat housing enables you to control the fan, however what i was thinking is, if the 2 wires are no longer hooked directly to the thermostat housing the machinces thermostat reaching the oil temp in which the fan would normally be automaticlly turned on, turns the oil light on not knowing that the fan is already running. So heres my question is it possible that the oil light goes on only cause the thermostat does not know the fan is already on to cool the oil down, because recently i saw my oil light on and since its been latly an ever growing problem i decided to keep riding with it on and even with 20 minutes of riding with it on it does nothing nothing happens no siezing,nothing. i can't really understand, iv'e check my sensor, its fine iv'e checked my jetting, it great iv'e changed my oil and coolant many times so that should be fine please help me resolve this. thank you-Rick

 

My conservative advice is change the wiring back to the way it was. If your fan and temperature sensor are working, your oil/temp light should not come on for high temperature reasons, certainly not with the stock motor.

 

ok well this is my new name on here i would rather the fan run the whole time and the oil light just stay off why do u figure its comin on? thx

 

I could be wrong but this is what i think, by putting a toggal switch in there to run the fan direct or all the time will not affect your oil light at all. What you connected is the fan thermastat switch all this does is kick the fan on when the temperature sensor tells it that thev coolant has hit a certain degrea and it needs to turn the fan on . As far as the fan cooling your oil it doesn't unless you have a oil cooler which is basicaly a radiator that the oil passes through.There is a oil pressure sensor that may be kicking your light on and you might want to check the connection from the sensor all the way to the light. This is from shade tree mechanics 101 if it helps im glad i could help you if it doesn't im sorry becouse this is only what i think.

 

Ok thank you 2big2fast, so what ur sayin i should do is check the wiring to make sure there are no faulty wires? if not then what?thanks

 

If all your connections are good , and you dont have any brittal wires you will want to take a look at the oil pressure switch and the overheat switch. Have you ever cleaned the screan inside the oil tank. it could be kicking on for lack of oil pressure. if you dont have good oil flow i would think that might cause it to kick the light on. let me check out the lights on my bikes , maybe its something simple.

 

Thanks I appreciate it, The oil screen is by where the hose leaving the tank or the bolt looking piece at the the bottom of the tank?
Also I have been changing my oil and i know this may sound stupid but i havn't been changing my oil filter because the place to go to get one is like an hour away and havn't got the chance to get out there, so its been like 5-6 oil changes with the same oil filter could this have anything to with it.
I would think the oil light would come on as soon as i turn the bike on if i didn't have good enough oil presure, rather than later cause as u run it the oil looses viscosity and becomes more easier flowing? thanks again

 

Its tough to chase ghosts. Find out what the real problem is and then try to fix it. First get a manual oil pressure gauge and put it in place of the oil pressure sending unit. Ride our bike and see if the oil pressure does fall off. I would be suprized if it does because of all the times you have kept riding with the oil light on. Once you know that you have good oil pressure, then it is a matter of locating and fixing the electrical problem, ie; bad sender, poor connections, etc.
You can also reconnect your temperature sendor and connect your toggle switch in parallel. That way the switch will keep the fan on if you want, or the sender will turn it on if the engine starts getting hot.
As to the oil filter, you are really taking a chance by not changing it with every oil change. That may be part of your problem. They aren't that expensive, buy two or three at a time. Did you pull the fitting out of the bottom of the oil tank and clean the wire mesh? Keep it simple in your diagnosis and you should find the problem. Good luck.

 

On a 2000 DS, when you change the oil you have to bleed a little air out of the system by turning the screw behind the oil filter.
If you don't bleed the air the oil light most likely comes on. I know mine does. So, It may sound like a dumb question but, after you change your oil are you bleeding the system as the manual says to?
I ask because you wrote;
"Also I have been changing my oil and i know this may sound stupid but i havn't been changing my oil filter because the place to go to get one is like an hour away and havn't got the chance to get out there, so its been like 5-6 oil changes with the same oil filter could this have anything to with it.

The later year DS's fixed this problem, with a by-pass line, so the owner manual may not contain this instruction.
Also, You can buy a reusable oil filter from http://www.americandirtbike.com/k&p.htm

 

If you have not changed the oil filter in six oil changes what kind of hours are we talking in between oil changes? You might want to check with your dealer and ask about a engine flush. something you can put in the oil to clean out all the build up and while your there get yourself about 5 filters, you can never have to many. let me know whats going on.
