You can unplug the wiring connector that comes out of the front of the VRO and see if the horn stops. If it does not stop, probably a grounded wire under the helm.

If the horn stops after unplugging connector then it is probably a real alarm. A steady alarm means a no oil allert. The VRO (varriable rate oiler) counts the pulses the oil diaphram makes and compares them to the pulses the fuel diaphram makes and sounds the alarm when they get out of kilter.

oops! sorry for the rambling... but that would be a good place to start testing</TD></TR></TABLE>
