Trying to figure out what this is all about. As standard the battery is connected at the top left. Its fused from the right side and also the starter/alternator on the far right. The 4 power connections to equipment Blue A & B and Green A & B are also fused. It all seems a bit extreme to me - I haven't seen this with any other car. I can't really think why there is protection between the battery and starter/alternator apart from maybe connecting the battery the wrong way round - the fuse should then blow. If any equipment tries to pull too much power the fuses at Blue A & B and Green A & B show go.
