Temp / Oil Alarm For No Reason

Recently I have this annoying problem. Only when wet and damp out does this happen. Start engine cold, after a few seconds alarms starts to sound, sometimes scratchy like a poor connection. When really wet & damp sound is solid. Turn engine off and just key power on, same noise. After a dry day all gauges clear no dampness, sound goes away, might stay off for a week or two if no moisture. Checked small oil tank seems fine, played with float, seems fine. My guess is, the over temp alarm is grounding out some where when damp. Where is this? How many on a V-6 ? I’m assuming that’s how the OT alarm works, when closed to ground will close circuit and cause alarm to sound, I could be all wet. Any idea’s greatly appreciated?<br /><br />1997 Yamaha 250

Re: Temp / Oil Alarm For No Reason

Would it be an electrothermostatic sensor linked to each of the 6cylinders, measuring max. tolerable heat range? Would make sense. Just wonder if the moisture and dampness occur while it is COLDER at the same time, affecting the viscosity of your oil and its sending capability, indicating possibly the oil pump's inefficiency under stained condition. This is conjecture, and I am a novice, but no one had answered your post, and it is frustrating when that happens. I go on the premise that all of our ideas are better than any of our ideas in regard to stumbling onto solutions; however, if there is a veteran out there, please correct my guesswork with facts.

When the buzzer sounds with the key half on, this would seem to me to be a primary warning signal-to not start the motor until a problem is fixed.
