This device was an easy fix. Some wire, a couple of probes, some grommets - and we’re done. Cable is even color-matched to the unit!

I scrubbed the case down, and gave the switch a spray of Deoxit as a preventative, even though whatever the OEM used was not really tarnished like other switch rings I’ve seen.

So. Does it work?

Sure does! The new battery reads as a new battery.

That’s all for this device, it goes on display until needed. Stay tuned for more EICO 950A goodness!
