interferance

[marksullivan]

the flasher on my bow mount works fine when not under power. When the troller is running I get interferance. Never had the problem untill I put in another lcx 15 mt on the back. Could it be the problem or is there some other wiring problem to look for. thanks

It sounds like it could be the problem; what frequency is your other depth finder running at, or, what model & brand is it?

Also, where do you get power for your depth finder in the bow? If it's from the trolling motor batteries I'd try running it off a vexilar battery - if that takes care of your problems you should hook it up to your starting battery.

try twisting you power wires. I am a ham radio operator and I know i have heard to twist your power wires that way you reduce power noise on you radio. it could also work for a graph too. just something to try.

heres more information. It does it with none of the back finders running. With everthing off but the front locator and trolling motor. finder workes great until I turn the motor on.

is the trolling motor on the same battery?

[jeffreyd]

as noted above you could try twisting the power and ground wires together to limit the amount of RF that is being produced. You could also buy a filter for the wire to keep the noise out. Several options, are out there,

Or you could rewire your locator to get power from your starting battery and not the trolling motor battery. That should take care of it as well.
