Bongo Fury

Having worked out that my problem with the remote central locking, thanks to Geoff g8dhe, is the lack of power in my leisure battery, I've returned the top left fuse to the main battery but the locking is still working from the leisure battery. Maybe the sensor is powered from that fuse but the servo isn't.
Does anyone know which fuse is on the power to the locking system?

Yes the switch that drives the electronics is powered via the Top left fuse, however the power for the actual door solenoids is from below, which will normally always be fed from the SB;

Thanks Geoff.
