Thanks to all who replied to my earlier post about this matter.
I have just had a second battery fitted to my Defender, for running auxiliary equipment. Both batteries are 110 AH, and 110-amp cable links the two batteries (I am told), with a manual cut-off switch in the cable between the negative terminals.
Lighter-type sockets and two sockets from which household-type plugs can run have also been installed. The electrician hadnt fitted fuses for two of the sockets, but Ive asked him to fit fuses for all four.
I have read that two fuse holders and fuses should be fitted in the main linking cable, one on each side of the cut-off switch, but the electrician says not needed. I have also seen that in a recommended set-up, the cut-off switch is in the cable running between the POSITIVE terminals.
1. Am I mistaken about the need for fuses in the main linking cable, or is he?
2. Does it matter whether the cut off switch is inserted in the negative cable or in the positive one?
