Hi, I needed this myself, found your post but no solution so after further... here you are. I tried it mated to a lowrance NMEA & it worked fine. Mine had a busted plug so the wires were already exposed with the pins handy to connect straight into a screw connecting block!
If you're using a raystar 125 antenna, you will have to power the red wire + and the shield wire - separately. Sl70's don't provide power over seatalk. Also make sure your green and brown wires are properly connected. If it's a 120 just power the red and sheild(black) and leave off the all except the yellow that's your data. If you still have nothing may probably have a problem in the antenna itself.
Make sure that you have powered the NMEA 2000 network. The display
unit's power cable has a set of red, black, and sheild wires that need
to be hooked up to a 12VDC power source. There is a power diagram
somewhere in the manual that should show this.
Make sure that
you have the NMEA 2000 network connected properly. If it is a newer
version LMS-525, it should just be a single 15ft cable that has two female
ends, the module plugs into one end, and the other end plugs into the
back of the display. If it came with some T connecters and 120Ohm
Terminator caps, then make sure you have that hooked up correctly.
There should be a diagram in the manual for that as well but you just
connect the two T's together like TT, put the 120Ohm terminators at
each end, and run the extensions to the display and GPS module.
is a decent troubleshooting guide for checking to make sure power is
getting to the module at
If this doesn't tell you anything, most likely the GPS module is bad.You will need to contact Lowrance support to get it repaired/replaced. You can call them at 800-324-1356 or email them at http://www.lowrance.com/en/Support/Product-Support/Contact/
Yes you have to hook up the red wires together to the + and both black ones to the negative, otherwise the antenna won't be supply in current , and don't forget to insert behind the red wire a fuse and a switch to avoid to discharge your battery .
if you have the model with the antenna that extends itself as opposed to the stationary ones, then you might have to. we're having the same problem with my friends neon, but we cant figure out which wire to connect it to.
if you get a wiring diagram for the car, it might come up as "power antenna/amp" or something of the like. with ford, i believe its a white wire, but i could be mistaken.
Hi. I have G series Raymarine and I listen the noise when swtich on I am not shure , may be from the ventilation (the fan).
I not find troubleshooting to G raymarine, I hope find the soulatoin thanks.
If it is an RS 120 or an RS112 antenna you do not need to change it.These are both active antennas in other words they do all the gps computing in the unit itself. You need to look at the wire from the antenna. If it is a coax cable(2 wire) it will not work.If it is 3 or 4 wires it will work. If 3 wire (red ,silver yellow) just hook up color for color.If 4 wire you are going to have to figure out the wiring for it from the units wiring diagram.That could be a big enough pain that you might be inclined to change to the new antenna. If you wire the new RS125 antenna you must wire it to the seatalk buss. The seatalk wires are Red Silver and Yellow.The wire from the RS125 are red yellow silver green and brown.Wire as follow to your sea talk cable.Yellow to Yellow, red to red , silver to silver, green to red, brown to silver.
Hope this helps.
I had this problem as well. On my harness was a wire for connecting the factory amp. You have to connect the Automatic Antenna wire to the Factory Amp Turn On wire. Should be a blue wire to a blue wire with a white stripe.
