Connecting humminbird helix 5 to lowrance link 5
On to my next dilemma! One for the technical gurus....
My lead came in the post on the day we were leaving for the iom, on digesting the wiring diagram it looked to only use 1 wire to connect both together, they did mention lives and earths to to power the radio but as both gps and vhf already have their own power supply I didn't connect them, however the units didn't communicate with each other, I had no time to look any further as we had to leave!! Have any of you guys had similar problems or know how to wire these things?? Thanks in advance, Tim.
Sometimes a little knowledge is worse than none at all....
