Credit Unit Unresponsive

The credit unit was not crediting.

The Credit Unit did nothing. Found that it had been forced beyond its end stop. It had been set to stop at 15 credits, but had been pushed past that point by some enterprising repairer wanting to "get at" a larger range. The unit will take 37 credits as a maximum. The enterprising repairer didn't bother to move the pin as intended, but just gave a mighty shove, perhaps with the aid of a lever. I'm not certain that the end result was what they were after - I certainly found it annoying.
