It back 40 years ago, and this pilot fish is working in the repair department of a company that manufactures microwave transmitting equipment for the telecom industry.
(But it 40 years ago, so you all should know who uses this stuff.)One bright morning, fish has a transmitter board in a jig so he can test it, and no matter what he does, the readings aren&t coming out right.
Fish opens the jig to see if there a problem, and finds that one of the wires going to the power supply is just barely hanging on by a thread.
He sees evidence of arcing that would explain why the readings are messed up.Confident that the tech assisting him has thrown the circuit breaker, fish reaches in to tighten the connection.
