    I reckon I usually take close to 4L out of mine, maybe just 3 1/2 at the least. 
    That’s pumping it out, not draining from the plug. 
     

    2L litres don’t sound enough.

    Are you removing with a pump?
     

    i always warm the engine up first,i`ve tried emptying both ways from down the dipstick hole with a pump,and also the pump thats on the side of the engine,still only about two litres,

    hi,i`m thinking of introducing a lithium battery to my battery bank,at present i have four lead acids i`m going to reduce this to two lead acids and one lithium( a hybrid system),my question is,the charging cable from my 70 amp alternator to the battery bank has to be longer and offer a certain amount of resistance can i get your thoughts on this cable size please?.many thanks

    Hi all,we are on the llangollen but thinking of checking out the Montgomery canal on the way up, does anyone know of any restrictions on the Montgomery, it says in my Nicholson that the locks at the start of the canal are only open certain times of the day,but my Nicholson guide is very old and wondered if this was still the case,many thanks in advance

    More information

    hi all,is it acceptable to add an extra battery to the existing battery bank via car jump leads,there are three 130 amp battery's in the existing bank now ,asking for a friend,many thanks

     

    Just to add a bit of background, there are three batteries in the bank,300 watts of solar,but still having to run engine twice a day to top batts up,so he is going to pop another battery in the bank to get through the summer, tia

    hi all, i have 4 leisure and a starter battery on my nb,i also have 300watts of solar,i recently fitted a smart gauge to monitor state of charge. i have noticed that there seems to be 14volts going into the battery bank constantly  from the solar panels even when the gauge shows 100% charged,is this ok,or will it fry my batteries,many thanks in advance...

  16. split charge relay

    Wot mtb says. But you could insert a battery isolator switch in the link between the two batteries, so you can isolate the start battery from the leisure when you stop charging.


    i disagree with this. The reality is that starting an engine uses very little charge, maybe 1Ah or less. And thus as you say recharges very quickly. And then ever after that (with your proposal) the main current going to charge the domestic batteries has to route through the relay, creating heat and voltage drop. Have the VSR by all means, but prioritise the domestics by connecting the alternator supply direct to the domestic batteries (via the domestic battery isolator to keep BSS man happy).

    so are you saying,alternator to vsr from vsr  to domestic bank as a priority then secondly to starter battery ?

    hi all,i`m going to take out my split charge relay soon(its packed up)and was wondering if i just connected the alternator charging cable direct to the leisure bank and took another cable from the alternator to the starter battery would this work ok,i only have a single alternator, many thanks

    hi all,a friend of mine is going to sell her 2018 widebeam, she fitted it out herself and is a live aboard,after having a word with the local broker she was told that before it can be sold it would have to be inspected and have an RCD certificate and the price of this is nearly three grand,does this sound right? many thanks

    Then it really needs to go, unless it's one of the expensive electronic gizmos often sold as zero volt drop diodes. If it is, then it sounds as if it still needs to go because it's 

    What do you recommend I should replace the diode with,tia
