For some reason my oil light is coming on gradually as I revs increase. The light is one as it should when I stat it it goes off as it should but I when I rev the engine or when the rpm increases the light gradually comes on. My second question is it an oil pressure gauge or a oil level gauge?
Thanks! Y’all have helped me so much over the years.
According to the parts diagrams the 83 spectre has an oil level switch fitted to the oil pan. The oil pressure switch that is fitted to the KZ750 E & H etc. isn't in the diagrams so I assume it's just an oil level light. If there is a sensor under the timing cap, then I'm probably wrong and there is a pressure switch as well.
When did this start happening? Is your oil level OK? Did you change the type of oil you use?
It could of course just be an electrical problem. The switch will provide the ground connection for the light. I may start to ground out due to the vibrations. Check the wiring under the oil pan.
Here's a table from the KZ750 manual. It's in the 83 model supplement but I'm not sure if it applies to the spectre (only the H, L and ZX models are referred to specifically). If you have two leads going into the sensor you can test the resistance between them and make sure it is in range. If you only have one wire, you can probably test resistance between the wire and a clean spot on the oil pan (but I'm not sure you can go by the values in the table).
OK, I would assume that the warner unit detects the disconnected wire and grounds the light to turn it on. It may be a fault in the sensor. Someone should correct me if I'm wrong, but the oil level in the pan should drop slightly when you rev the bike. It may be that the sensor it just a bit off and thinks that the level is too low. You could test the resistance of the sensor but you need to remove it which would mean draining the oil again. There is a page describing how to test the sensor in the manual.
If the sensor is just reading a bit low, then you could just fill the oil to the top mark on the sight glass and see if it gets any better (or drain some oil to the lowest point and see if the light is always on). Stay within the marks though
Just got done checking the sensor and it seems to be working correctly. When I have it right side up the volt meter shows nothing and doesn’t beep. Once I turn it upside down the volt meter starts reading and it beeps.
The reading shows a bunch of numbers then bottoms out at 0.00 Ohms. Which it’s supposed to do. So maybe my oil is still actually low. Idk I’m gonna buy some more oil and see if adding some helps.
