By June 2011 the HOVR, Z23, Z24, Z69 board had been properly installed in 50030's cubicle and the associated wiring completed.

Here the finished Generator Field relay board is seen in June 2011. Left to right, the items are the Overload Interlock Relay (OIR), Generator Field Relay (GFR) and no.1 Blower Motor Relay (BMR1). The grey box far left houses the Control Circuit Governor (CCG), and just visible above BMR1 is the Battery Charge Ammeter Shunt.
