A new terminal block was completed in April 2012.
A special terminal block was mounted on the rear of the tank so that communication wires could be connected.
In a new terminal block, that short circuit would not cause a spark.
Connections can either be soldered, or made using terminal blocks.
The whole terminal block's come loose at the end of the cable conduit.
They manufacture terminal blocks and test switches under the trademark States (existing since 1940s).
To do it yourself, use a standard modular jack converter, which will fit over the old terminal block.
The Auburn and Rochester built its terminal several blocks away.
Some older 747's have terminal blocks, or places where wires connect, with sharp edges that could damage wiring.
