Ok: I did some testing on the light and pressure switch. First off the pressure switch has to have less than 3 psi to turn on as per the service manual. I can't believe the pressure would be so low. I replaced the oil pressure switch with a gauge 0 - 100 psi. BTW do you know how difficult it is to find an oil pressure gauge with metric threads. If you need one, good luck. At idle cold or hot, there is about 20 psi of pressure. The service manual says at 5,000 rpm you should have 71 psi, however I'm not going to rev the bike that high, no way. As you bring the throttle up, warm or cold the pressure increases and at about 2,700 rpm plus or minus my engine is at almost 75 psi, right within specs. So I have good oil pressure.
If I disconnect the wire to the oil sensor, the light goes out like I guess it should. In the service manual it says to get a voltage reading with the wire disconnected. Between the blue with red strip wire, the one that is hooked to the sensor and ground you should have 12 volts. That's what's weird, I only have 7.49 volts even grounding direct to the battery. They say to do it with the bulb in the circuit, 12 volts, I'm only getting 7.49 volts. Is this because of the LED instead of the 194 bulb, I don't know. The book says if you don't get 12 volts, either the bulb is burnt out or the wire is shorted out or something else I don't remember what it was. I know the bulb (LED) is good and the wiring is good because the light, LED, bulb, whatever Lights up before you start the bike and goes off once it is running. So this is telling us something, but, whatever it is , it is out of my league. Anyone of you know what's going on here???
