Hi Aj..........[firstly always turn the white isolator switch back of carriage off before doing any work on lift as you could short/blow fuses on main pcb and turn back on when finished].......[[You should only have the red/black wires coming from pcb and the orange inline fuse linked between batteries]] 1/..Connect red/black lead to main pcb first ,where they were connected to in the first place then run the two leads so they come up between the two main batteries..connect Red lead to red terminal on one battery and Black lead to Black terminal on 2nd battery,,then to make the circuit between the two batteries you use the orange inline fuse connector which one end goes to Red terminal on one battery and the other to Black terminal other battery,,so in total you have connected two 12v batteries together making 24v"s to run the stairlift ....Also when testing the batteries on lift you need to put your meter leads on the red and black wires to show total voltage in your case 24v then test run the lift if voltage falls below 21 to 22 volts the batteries either need replacing or leave them to charge overnight.......Hope this will help.........paul/portsmouth/uk
