alternative to step down butt conectors
 
Hello all

I have single power and ground wires running forward to my pulpit mounted navigation lights. Each light has a single ground and hot wire running from each. So I need to connect two hot wires(one from each light) to a single hot wire running back to the panel(same for the ground wire). I am using step down butt connector but find it awkward to get a good crimp. Are there any alternatives? Do I just need more practice with the crimping tool? The step down butt connector is marine grade and the right size for the wire being crimped. The crimping tool, while not a klien grade tool, works great when crimping standard butt connectors.

thanks,
John

There are different crimping tools for different types of crimps. The adhesive lined heat shrink crimps use a crimping tool that looks like this;

Look closely at the jaws;

The insulated butt splices that most average Joes use this type of crimper;

These jaws will tear the insulation of a heat shrink crimp.

For what you are trying to do; first use the right crimper for the crimps that you are using. Then, if you are trying to crimp a smaller gauge wire to a larger wire, (the electrical weenies are gonna have a fit, but this is what I was taught to do - and it works) strip double the normal length of wire, then fold the stripped wire over so that the end of your 16 gauge wire now appears to be 12 gauge.
