Here is my two cents worth Skipper.
First of all there are several flavors of crimpers.
Calibrated crimpers such as https://www.amazon.com/Thomas-Betts...89923685&sr=1-4&keywords=thomas+betts+crimper
Regular crimpers such as this https://www.amazon.com/Thomas-Betts...9923685&sr=1-12&keywords=thomas+betts+crimper
Now here is the caveat Skipper and listen well young grasshopper.
The tool or the force DON'T MEAN ANYTHING if you are using cheap big box or Vato Zone crimp on terminals.
Look up Thomas Betts ,Panduit or 3M crimp terminals they actually make terminals that are the real deal.
See the OD of the barrel of the terminal is what compresses the wire so if you have cheap thin sheet metal folded over for a crimple barrel, (which is predominantly out there) will it supply as much force as copper ferule?
So don't send big money on a fancy crimp tool spend money on good terminals and you will be happy.
BTW I have used both Panduit and Thomas Betts and if installed correctly, the wire will break before any failure at the terminal.
Then we can get back to important discussions like what ever happened to your DA pad?
