Hi. I am in the market currently for a Garmin 540S and plan to connect it to my Standard-Horizon Quest Plus VHF radio. What type of splices are used for the tiny wires that connect the GPS to the VHF?

Strip, twist, solder, wait to cool, cover with Ancor hot melt lined heat
shrink, shrink. Be sure to slide the heat shrink on before
twist, and keep it way from the solder heat.

The harder question is which wire to which wire. I've got
the manuals for both on the home computer and can look it
up Sunday.

Or you can do it this way. 13081807/file.jpg

Tom -

That is a very clean looking connector. Where can you get those?

Agreed. I NEED that clean setup in my cc!

The Radio Shack down the street is literaly next to the West Marine. I'll be glad save myself some money and walk into the former. Thanks!

On my boat I use a very small terminal strip as a connection point. The terminal strip uses 3-48 machine screws. I found these by chance at the bottom of a dusty drawer at work, and I have been trying to find a retail source for them. But so far, I have not located one. They may not be made any more.

The screw binding posts like those mentioned above are not the perfect solution, but they will work. In modern electronics we are seeing more situations were small gauge wire is to be connected to a terminal strip or binding post, and there are connectors designed for this. Unfortunately, the connectors are not readily available (as from a Radio Shack store or similar outlet), and they all seem to be designed for mounting one portion on a printed circuit board.

I was thinking about having a small printed circuit board made and mounting several of these binding posts on it. Then by use of soldered jumper wires between connectors you could configure any kind of interconnection arrangement desired.

One drawback of the Standard-Horizon radios is that their data input and output wires terminate just in pig tail leads; no connector is provided. This makes removing the radio from the boat much more difficult. (Removal of the radio is often necessary due to concerns about theft or very low ambient temperatures over the winter.)

I use heatshrink disconnects sized for the type of wire. That way I can unplug the connections fairly easily.
