I might have you send me the installed terminal and I'll slice it open for microscopic examination. How many die sets come with the tool?

If so, does it have a rating? I've seen similar in th e racing world where they bolt the connection through. These work perfectly fine so long as you have the correct device intended for the job. The below uses a 3/8 bolt, but there are many variations on this product. I f you go this route be sure to protect the exposed bolt from contact with o ther gremlins.

Fire wall feed-thru products like this are electrically adequate and VERY convenient. Just be aware that plastic insulators would not pass muster in the TC aircraft world with respect to maintaining fire wall integrity. Admittedly, fuel fed fires under the cowl are VERY rare events . . . and we know that those-who-know-more- about-airplanes-than-we-do are fond of writing rules for mitigating the rarest of risks. A lighter, less elegant but time honored and much tested approach is to bring unbroken wires through the fire wall protected by shielded grommets and sealed with a fillet of fire-putty on the engine side. It's your airplane . . . your call. Bob . . . ________________________________ Message 5 _____________________________________ Time: 08:11:13 AM PST US From: "Robert L.

That's a pretty good range. Too bad they didn't make those hex shaped holes tailored more closely to the real-world of terminals. But then, we have no knowledge of what the designers were handed for design goals . . . nor the market demands that drove the decision to fabricate the tool. I'll be interested in seeing what your test crimps look like.

I think full dim for my EL inverter cube was around 5 or 6 volts so I altered the design a bit to still have full range adjustment on the knob.
