    Hi guys , can I run my dual output regulator just to my leisure battery until I can find a way to get a wire to my cab battery ? .
    Also , I have a 120watt solar panel which comes down to a 6 way fuse block , then the regulator (10amp ) .Is a 10amp fuse correct to protect regulator ? . Thanks in advance .

    That isnt right.....you are getting unregulated power to the fuseblock....could be as high as 17v.
    the panel should go directly to the regulator.

    Sounds about right, your panel can go straight into the regulator or via a fuse/switch, but the regulator should be self protected from an overload / short on the panel so not needed, then you need a fuse as near to the battery as possible to protect the wiring from the battery to the regulator and the regulator itself, the regulator should be rated to the panel, as said 10amp sounds about right for the regulator/panel but the regulator could be higher to give the option of more panels in the future.
    The regulator should be fine left open circuit on the second battery output just don't short it out.

    I had a similar situation and had no problems connecting one output of the dual output regulator to the leisure battery until I had the time to run a separate fused supply to the engine start battery.

    OK ,controller is 20amp . wired in panel and connected to hab battery only . showing charging , albeit at a low rate due to cloudiness . remote panel shows a red error light which the instruction book says is because only one battery connected .happy days , now the hard part , finding a way from controller to cab battery .

    @Bluestar , the length of 4mm cable from fuse box to hab battery is about 2 foot , should I still fit an inline fuse on positive cable near battery as well ?

    I went under the van with my cable, run in convoluted conduit to my to my hab batteries. earth and live from the regulator.
    Depends about fuse...... belt and braces, if anything were to happen or to short that cable you would put the whole amperage from your battery down to earth not good . if there were NO chance of anything shorting then not so important I would have run the regulator direct to the battery with the in line fuse at the battery end
    With a 20amp controller you could add another panel at a later date if you wanted/

    Under the van is an option that I've looked at as battery box is suspended in cab floor and has access from below , just got to avoid getting too close to exhaust . I will add the inline fuse as a short would technically be possible as all the electric wiring and charger etc are down there , as you say belt and braces . thanks again .

    Not an expert but happy to help, give us a heads up when all up and running,
    I ran my conduit along the chassis rails with cable ties, yes plastic conduit, exhaust, not good :)

    OK , all now up and running perfectly . fused next to both batteries . I ran cable to cab battery under drivers seat across under cab insulated floor for 4 inches and down into battery box , all neat and tidy .

    Colin,
    Where did you source those smart corner brackets for the solar panel?
