I am trying to install one of these multiuse voltmeters, cig lighters, etc. (see picture from Amazon). I have found a location, drilled my holes which fit! - yeah me- I’m not so construction capable, found a suitable circuit, tapped into said circuit, Bought wire and tried to crimp the wire to the insulated blade connectors, bought more connectors, cause my wire wouldn’t fit. I finally was able to get it to work and turn on. I mocked it up and tried to charge my ipad. It worked but it got HOT, very very HOT. Then when I went to move it, half or so of my crimps fell apart. So I have several questions. What gage wire do you use with these things? I was trying to use 14 gage, but getting 2-14 gage wires into one blue spade connector is not possible. I tried a larger connector but this also did not work well. I do not seem to be able to get a good crimp. I have watched video after video and I just think I do not have the hand strength. I understand the principle and have the right tool, but mine just fall apart- before I can even wrap them with electrical tape. Are there other options I could use? IF I use a smaller gage wire, say 18 will the usb plug get as hot?
