Hey guys I'm working on a 98 fourtrax and the oil temp light stays on. Tried testing the switch with a test light but it's not grounding out at all whereas the plug itself is grounded. I'm assuming this is gonna be a short in the wireing as I had to rewire my neutral safety switch. Is there a way to test my oil temp switch before rewireing so I can make sure I won't be disable in anything? Thanks in advance!

oil temp switch/sensor is bad ?, or not a clean connection to it ?. I can't remember if that year has the alarm box mounted beside the c.d.i. ?, if it does ?, it has green connections on it.

my confusion is that when I unplug the wire from the switch the light stays on so I think one of the wires is grounded on the frame or shorted out. Causing it to stay lit. I had a similar issue with my neutral safety switch but it wasn't getting a ground at all and I had to rewire it. I plan on running a new wire from the oil switch to the control box mounted under the handle bars. But I wanna make sure my switch is good first

wellllllllllll, your thinking backwards here bro !, all switches are wired hot !. when they ground, or in this case, detect hot oil ?, or look for neutral ?, this is when they become grounded !.

 

[Camohurley4x4]

When the switch detects it getting hot that's when it sends the ground signal to the oil temp light correct?

 

[Camohurley4x4]

I have the plug disconnected that runs tge reverse neutral and oil light. But oil light is still on that's why im assuming it's ground out where it shouldnt be

does not send anything, it acts like a light switch, when the oil gets to hot ?, it pretty much closes, this acts like it grounds out, this then turns the light on.

That's what i mean by ground signal sorry I've been working at a Honda car dealership and still have the newer car language stuck in my brain!

does your model have the alarm box under the front fender next to the c.d.i. ?.

lol, next you will wonder how the stator makes AC voltage, and yet every part on it runs from 12 volt dc !..lol. no worries bro .

Possibly there's two there ones bigger and ones smaller

ok then, yes, you have a alarm box !, when your oil light stays on ?, and switch is good ?, that alarm box goes bad, unplug it, I bet the light goes out ?!. . DO NOT LEAVE IT UNPLUGGED/REMOVED !, that box shuts your c.d.i. down in the case of an over heat from lack of oil !.

I unplugged it and plugged a brand-new one in that I had sitting around( I ordered parts for my uncle's to put on for my grandfather to have it but haven't been able to make the 5 hour drive); and the oil light came right back on.

ok, plug that connector back in from the wire harness, reach down, and pull the connector off the switch itself, its the switch at the front behind the metal cover, should be one wire going to it ?, unplug it from the switch with the key off !, turn the key on, light should be off ?, when you touch the wire to the engine, then the oil light should come back on ?. if this goes like I say ?, then plug the switch back in ( key off first ) turn key on, if light remains on ?, then your oil temp switch is bad.

 

[Camohurley4x4]

With everything plugged back in and plug removed from the main switch under the cover the light remains on. That's why I think there's a burnt wire or a damaged wire. The neutral light wouldn't come on at all and I couldn't use electric start so I had to wire it around and back into the main wire box on the forkand now lights on in neutral and only in neutral so I'm thinking the oil temp light is along the same issue

Also if I take my test light connected to 12v and touch it to the plug itself it's lighting up saying that the plug is grounded out without even being hooked up

hold on a sec...what are you, or where are you putting the test light ?, harness side ?, or switch side ?, the switch will not be hot if your test light is clipped to the engine, and not the hot side of battery ?!. only the wire to the switch will be hot with key on if test light is clipped to engine for ground, or neg on battery.

 

[Camohurley4x4]

With my clip to the positive battery terminal and the probe to the harness plug it's showing that the harness itsself is grounded out with an old cheap off-road light attached to the positive terminal I touched the ground wire to the plug that is on the harness and my off-road light came on confirming that the harness itself is grounded somewhere that it shouldn't be.

I guess you could say I'm checking everything backward in order to locate the issue since I have a light that won't go out even after disconnected ground I'm trying to trace the wire for the unwanted ground.
