For many hams the go-to 12 VDC connector is the Anderson Powerpole®. I feel the same, this connector is the only one that makes sense for convenience and durability of connection among my own radios and if the need arises other power supplies. This form of 12 VDC power connection really makes the issue of interoperability for a power source a non-issue. The connector is recognized across the Country as THE power connector to use for ARES and other public service applications.
Anyway, where this is leading is the issue with installing the connectors on the wire. It really is not difficult but there is a standard, in order to interface with the rest of the world! Amateur radio has adopted the standard that when viewed from the contact side, the mnemonic for remembering the arrangement for the positive connector is: “Red Right — Tongue Top“.
Of course red is positive while black is negative. Even though there is a standard, I feel it is still a good idea to confirm the connection that your rig may be connected to is verified visually and also electrically using a volt meter or one of the LED connectors that indicate if the connectors are configured to the standard.
The installation of the connector contacts can be problematic if the proper crimp procedure is not used. I’ve used the crimping pliers type crimp tool, until now. I finally invested in a crimp tool made for the Powerpole® connector contacts. I have to say that I should have done it sooner, no exaggeration! There are are several styles of crimpers available with the special dies for the crimp, study their operation and style then decide for yourself which one suites your needs. The version that I settled on has a feature in the tool that helps maintain the alignment of the contact while the crimp in done (see photo). My opinion is that the crimp done with the pictured tool is far superior than the crimping pliers style. Along with the quality of the crimp, there is no distortion to the contact. With no distortion there is no reforming the contact which results in a much easier insertion into the Powerpole® shell and much better contact surface for maximum conductivity.
