I have wasted 6 MC4 ferrules trying to connect them to 14AWG wire using the I2 dies. They always end up mashed and deformed. I finally succeeded using the middle opening (labeled 12AWG). That seems to form the proper crimp that looks as expected and seems to hold firm. Am I doing something wrong? Has anyone else experienced this? It is almost as though the die is not sized properly for 14AWG. I was using MC4 connectors from 2 different manufacturers, each sold as being suitable for 14AWG-10AWG.
I went directly to the vendor NOT Amzn to make the purchase. Same price. Shipped quick.
I just bought this tool with 5 dies that match most of my needs and it works great. The tool itself is sturdy, nice to grip (for my hand size) and easy to release (all things I have had issues with with similar crimp tools), the dies I have used (A3, C, D) have been pretty much flawless (a little paint that wasn't centered for the A3 one - who cares).
However, I would really _love_ to see a "C1"-die for smaller dimensioned open barrel terminals, such as for dupont and JST-PH. I am sorely missing those dies before I can get rid of my old crimp tools.
