:oops: Good evening to you all,whilst I am a newby I am not really one of you YET,at present I am making do with a wee "Toyota Townace" mpv. My query is this I wish to use a spare battery I have just aquired[75amp] for my lighting. As I understand it I can take a lead from an ignition controled source to a relay then on to the battery to keep it charged whilst on the move.If this is so [a] as I have a cigarete lighter in the back can I use this as a plug to connect the relay to, if so is there a specific size of wire I should use.I realise not having a "proper mobile "as yet puts me at a disadvantage with all you proper people but would be obliged if some kind soul would take pity on me with the answer to my question. Thank's in advance to who ever may answer me.

Hi

The relay should be connected to a charge light wire as the trigger, this is different to being ignition controled an ignition controled unit would connect the front and rear battereries merely by switching the ignition on and not having the engine running and producing power.

The Charge light wire only becomes positive when the alternator is producing power.

Fuse, if the battery for ighting is ever taken really low discharge upon start up it will try to draw full ampage for a short while, which can blow the fuse, I would try using a fuse a couple of amps down on the cigarette lighters fuse and see howyou get on.

Wire thickness gauged for 30- 40 Amps

How are you going to vent the leisure battery? as it got a vent tube? Make sure the battery is really well secured otherwise an emergency stop could prove less than entertaining. Also with it being in an accessed area do make sure the terminals are well insulated against accidental contact.

PS all are welcomed here, whethor you have no van or £250,000 worth

Not wanting to hijack this thread but ........... In nice and simple terms(I'm not that good at electrics) would this set up be the same if I wanted to put another battery hooked up to my leasure battery :?:
