Hi,
I have a dual battery set up with split charge on my 110.
I think the set up was fitted from new to serve the winch fitted on the front.
1st battery obviously runs the engine, 2nd battery is a optima battery directly wired to the winch.
There is a dual charge relay (I dont know any more details about it) that is wired with 3 wires.
1 wire to + on the 1st battery, 1 wire to + on 2nd battery, and 3rd wire goes on to the - on the 1st battery.
Can anyone explain to me how this would work?
Anyway, it clearly doesnt work as the 2nd battery has gone flat today after a small winching job so it would appear it isnt charging the 2nd battery.
Ideally I want a set up that charges the 1st battery first, then the 2nd battery, so my engine battery is always OK.
At the moment it is set up how I want for the discharge, ie, I cannot flatten the engine battery by using the winch.
I suppose I just need to replace the relay, but I just cant get my head round how that system works. Does it just charge the 2nd battery when the 1st reaches a certain voltage maybe?
