My ohm meter arrived and my rig tested at an acceptable (?) .249 ohms.
Aside from the fact that I really don't enjoy it, the ELA is performing great with the flat button and light spring. No arcs, zaps, buzzes. The ELA gets warm, transmitting heat from the 454, but the VTC5 remains cool. I'll switch around the button configurations periodically.
Wait, I just had a button buzz. Very short. Still don't know what that signifies.
Anyway, here's my setup.
