Re: warning alarm bursts -- Why?
I can see how a defective beeper can trigger--but I would imagine the defect would be a continuous beep.<br /><br />The beeper is not aware of engine speed. Only the warning sensor at the VRO is aware of engine speed. <br /><br />I'm pretty convinced of a restriction or a bubble in oil feed. jadee, is there a chance you had the same thing??<br /><br />(Thank you Mr. Seahorse. The VRO guide was excellent.)<br /><br />jadeeinc: what did they charge you for the new horn?<br /><br />By the way, there are some intelligence in the horn. (I do know electronics..) Well, I wouldn't call it intelligence--but there are semiconductors in the whistle-type horn. It's "potted" in an RTV or similar. If moisture gets to the device, it could affect it.<br /><br />(*The reason I say "intelligence" is as follows: The horn knows to chirp one second on key-on. It then goes into the "slave" mode, where the tan wire, when grounded, completes the horn circuit. There may be some kind of voltage regulation to the piezo electric noisemaker, as well..)<br /><br />But again, the electronics would be affected by humidity regardless whether the engine were actually running or if it were at WOT.<br /><br />..And if it failed, it would not be pulsating at half second on/half second off or whatever.. (unless the voltage regulator of the alternator is bad.)<br /><br />I think I am pretty convinced the sensor is complaining.. (or "was" complaining..)<br /><br />One last thing: The operation manual says, "if this (oil starvation) alarm is sounding; and you must go back to port--it is possible to operate the engine at < 1500 RPM."<br /><br />According to Seahorse's FAQ, the OEM VRO was designed to run at 150:1 at idle speed. That's nearly "no" oil. Keeping in mind gasoline is a lubricant, I guess that makes sense.<br /><br />It's a good FAQ.<br /><br />This is one long memo. Sorry.<br /><br />Ken
