DIY split charge - Page 3

... and now the work internet decides to show the picture and I see it's a pic of the split charge system Ryan bought rather than the relay set up for lighting, damn technology!

Winch will draw as much it can from the alternator then seek the rest of the amps from the batteries.

But I know plenty of people who run just one bigish battery for winching without issue, Unless your doing winch challenge stuff a 2nd battery with splitcharge is not really needed.

So a lesser amp relay won't be too bad on a overland style vehicle where the 2nd battery is more for running stuff when the engine is off.

Cheers bud

So if I get this right my choices are:-

A) Another full size battery with on a split charge with a beefy relay to take the max draw from the alternator. Winch is connected to second battery.

-or-

B) Swap the Troll's main battery for a slightly larger one and use the old one (or a new normal sized battery) as the auxiliary one on a split charge to the larger battery via one of the smaller amp relays. Winch is connected to the main battery.

Think I'll go for go for A and leave my main battery doing it's normal thing with the auxiliary handling all the extras like the winch. Plus I like the extras on the T-Max like being able to link the batteries etc.

think that's the best bet tbh, leave the original battery be

What amps can it carry, does not look like many, Rick

think the split charge unit i bought is for charging a caravan battery, as its got a fridge hookup too, will have to see if i can change it slightly for charging a on board battery, as the battery will be mounted under the boot floor, the instructions go on about 12 N and 12 S towing sockets

Yeh, reckon your right as 6, 4 & 2 (numbering on the relay) are the +ve pins on a 12 S socket.

In thinking of just connecting the outlet on the relay that's supposed to go to the 12s socket, straight to the leisure battery in the boot?, might work that way

Banshee, you want this diagram,

simple 4 pin relay used for almost any simple circuit, pin 86 goes through a switch and then to the +ve feet to the relay, pin 30 will go to you're spotlights, this is daigram for a fuel pump, but just the same to wire up anything with a relay

I'm running 4x 552 roof lights on mine and use a 30 amp relay....more than enough

Who drew this diagram?
Not following any electrical convention is it?
What is -12 volts? unless they are running the system on 24 volts.

TUT TUT TUT

NOT IMPRESSED!

I would say that they are the earthing points.

never let your kids draw the wiring diagrams for you
