Re: Seatalk Cross Interference

Just an update on this: a check of the wiring inside our binnacle/steering housing showed a couple of suspect wires, so I re-crimped a couple of grounds and power leads. I had high hopes, but this did not fix the problem.

What did fix the problem was disconnecting the Seatalk 12 volt leads (red and black) coming into the ST4000+ controller and instead connecting separate non-Seatalk 12 volt leads. I got the power leads from those supplying my chartplotter. All is good now, with no apparent interference.
