Mefi3, alarm sound at over 2000rpm, 1 beep every 3 second, and goes off till you slow back down, all gauges normal and gear lube is full. Any ideas?

And no codes when scanned.

Pull a wire off each alarm sender one at a time. The alarm sender wires are tan with a blue stripe. Start with a drive lube sender wire.

Don't know what motor, but if it has a fuel pressure sensor (L29 or 350 mag) it could be a soft alarm

When mine does that it’s the water pressure sender/sensor
