Although fuses and relays have their place the seemingly knee jerk reaction by some of adding them creates another level of unreliability not to mention potential volt drop (see what I did there). Tracing one circuit on my car I found a total of four fuses, simply to ensure another circuit fed from samè battery source had one. KISS rules in electrics.
The 2006 to 2014 era of various PCB iterations all open to the elements was a bad one for Morgan. The advent of the sealed body control unit (BCU), already adopted by the rest of the car industry, was huge step forward in reliability taking over all the conditional tasks of the PCB plus a lot more whilst also communicating with ECU via CANBUS.
