I've been fitting a camera system to the MH and it would seem that this morning the electronics had seen that battery volts had been lost and the clock was reset (nothing had been disconnected). When I found that this evening I also noted that the mileage was three miles less than it was last time I logged it (I log every trip). The only interface to the electrics I was doing today was with the reversing light fuse. I'm just wondering how the mileometer can have lost that mileage. 2006 Peugeot Boxer (X244).
