There is a plug-in chager that has 2, two wires out and 2 batteries.
There 2 wires in a wire which are red and yellow, and the other are 2 wires in a wire which are red and black.
How can I connect to wire between the batteries and the charger ?

hi there, having trouble fully understanding your question but you should have 240v ac volts going into charger at one end and two pairs of wires coming out the otherside, they should be red/black 24v dc which should go to the rail terminal block[underside of rail top] and supply voltage to the 2 x 12v batteries in carriage. the other two wires should be yellow/black 12v dc which should connect to the lower terminal block[underside of rail]and supply voltage to the hinge battery located inside the rail at hinge join..i will say not all rails have hinges so the yellow/black wire are usualy cut of near charger on installation!!!!.......hope this helps.....ian...portsmouth uk..
