Hi Boys. I am back again with another problem. I purchased a diesel sound generator from Model radio workshop & fitted it to my larger model boat, the unit works well but when I throttle up or down the sound goes up & down with the movement of the radio stick control, but my motor cuts out both forward & reverse.I am using a BEC from (Action electronics) which has worked well for some years now with a Marine ESC-50 which has a built in ESC but not connected. can anyone tell me how I fix the problem. thank you.

Hi Angus,
To allow a Mayhemer to help you it be good to describe how things are connected to each other, the receiver and how they are powered etc and at what point do the motors cut out assuming they start..
Regards

Yes, what Jonathan says!
Does the motor work OK if you disconnect the sound generator?

Sounds like 'brown-out' again.
First make sure the main battery is fully charged. That generally means charging it up again.
If problem persists then disconnect the ACTion BEC and try using a separate battery pack (fully charged...) for the receiver.

Thank you all for your reply's. The boat is powered with a 12 amp hour lead acid battery & is fully charged, The receiver is powered with a Action BEC 6 V. The motor is a 300 Watt 13 pole motor driving a 1.5 meter boat through a 80 mm 4 blade propeller . The motor will run perfectly when I disconnect the sound unit & connect directly from the receiver to the ESC,also motor motor will run when I have the sound generator connected in the line from the receiver to the ESC but will stop when I put a few revs on the motor, some times it will run up to full revs for a few seconds & then cut out, sometimes it doesn't start the motor at all.The sound generator runs well all the time & revs up & down without any problem. It is only a problem when the sound generator is connected in the line from the receiver to the ESC to motor.
.12 volt Battery to--- 6V BEC to--- receiver--- to diesel sound unit--- to ESC--- to motor

Angus,
Can you use a Y lead from RX so that the ESC and sound unit both see a "clean" RX signal.
From your description it looks like the throttle output from the sound unit to ESC is suspect

g6swj I think you might be on the right track there with the Y lead, I can't pick one up here so I ordered on online should be here in a couple of days, I will let you know how I go with it

Hi. I thought I had posted the other night, But nothing appeared so I will try again. I received my Y lead & fitted it to the boat as suggested it has done the trick just fine everything works as it should now. I always get the information on this forum to get me up & running again. great forum. & thanks for the help. :-))

Please note that a 12V lead acid battery fully loaded may have up to 13-14 volts.... Way too much for a module that wants 12V .... Had a similar problem with my ESC units on my FV Cornelia Marie.
