I've been using an FTZ 94284 crimping tool for the battery wiring upgrade project I'm in the middle of. It's been working well, until I tried making some crimps on #4 wire yesterday. They are power lugs, with "J" and "H" and gray markings on the lug. The table on the FTZ tool says:
The color shown there is green, but it's definitely gray on the lug. Oddly, that's also the same die settings and color as a #6 terminal. When I crimp with the J and H the lug pulls off easily. So I switched to K K and didn't fully close the crimper. I know that's less than ideal, but not sure what else to do. I rechecked the calibration of the tool and it's good (16"). Even more odd is that I've used it in the past for #4 power lugs and it worked fine. So either the lugs are completely different (they are not flared starter lugs), or the K K dies have shifted, or I've lost it completely.
Any thoughts about what happened, or what I should do?
