On SS9 Antisanti – Poggio di Nazza he had electrical problem and the centre diff was locked which mean he had hydraulic pressure. Looks like the electric control system was an on/off system on SS8 and SS9.
Ss8, It was still 4WD but felt like RWD with manual shifting and no central diff
SS8 was the loss of hydraulic pressure, which is related to some kind of leak. SS9 was related to electrics on/off and most probably related to some damaged/faulty wire
