HB Mega360 Power cable

[MaPia]

 

can someone send me a chart or information about 10-foot power cable for Mega360 transducer

it has numer 490540-1 and 200402090152. There are three wires, one red and two black and I do not know which of black ones is negative (-). Which pin in the plug is negative (-) and which i positive(+). What for is the third wire?

The third wire is a “drain wire” to move electricity/interference out way from the power wires. It is the black wire that is not tinned. Humminbird is having some issues with what they are suggesting to do with the wire. Originally they were saying just tape it off (which from a physics of electricity perspective, seems like the right thing to do), then some people had some issues with electrolysis/corrosion of the screws in the M360 pod and someone at HB must have suggested that this was due to the open “drain wire” so then HB revised their suggestion to connect the drain wire to the ground. Now they are again suggesting to just tape the drain wire off and put it to the side.

 

I taped mine off and am not having any issues. I am biased, but from a physics of electricity perspective this is the correct thing to do. Thus, it is what I suggest and what HB currently suggests.

 

If you want to learn more go read about “drain wires and RFI”.

 

Good luck. Happy to try answer any additional questions.
