Mercy pro xs warning beeps

[PAT92B]

Last Saturday I fished lake of the ozarks. I ran from Coffman up to Indian creek motor ran great fished awhile then went back to Coffman so my partner could the bathroom. Just after starting the motor I got 6 beeps from the motor. I checked the pisser it was good the motor never shut down so I ran nice and easy back to the ramp the motor ran great no more beeps so after the bathroom break I started the motor up again and got 6 more beeps the motor seemed fine the rest of the day but always got the beeps just after starting the motor. I called the dealer Monday the service guy said its a low voltage issue starting battery is weak. The motor starts fine I'm running helix 9s I keep the console unit on standby while not running the battery is less then a year old I keep the batteries on a Minn Kota charger. Anybody have experience with this issue? Thanks for any info

There is no audible warning for "low voltage" so I don't know what they are thinking there.

Most likely the low oil sensor on the engine mounted reservoir.  (4-6 beeps every few minutes).  

The sensor is built into the reservoir so the fix requires replacing the reservoir and re-purging the O/I system.

That happened to me twice with my old Optimax.  Both times it took a new top oil tank like wrench said.

I know my oil is kinda low in the tank I got about 3" in the resevoir could it be telling me it's low

The reservoir under the cowling should never be low.  If it is then you have an oil leak or a crankcase air pressure leak.  

There's no oil level sensor in the main (big) reservoir.
