Hi all, As you can see, 3 posts in one weekend...it's been a busy one for me! Anyway, going camping and I need to charge a second battery. I have bought a 'W4 Combi Master' fridge power supply relay and charging relay...and a second battery! The instructions are a little confusing as they only tell you how to wire it up to a12S socket. I can get a cable from the relay to a live ignition feed, a cable to an earth and a fused cable to battery positive or starter solenoid live feed. I am confused as the instructions go on to talk about connecting red and blue leads from the grey 12S cable to the relay. Is it safe if I just don't connect these 12S leads? The relay has the following connections, and I'll try to explain where the wires should be connected... H/DUTY 12V - Fused Battery Positive or Starter Solenoid feed. Earth - Earth (I'm sure about this one!).
12V Ign. - A lead that is only live when the ignition is on. Fridge 12S Red - I don't have this. Batt. Tr. 12S Blue - I don't have this either. Batt. Chg. - Does this go to the Positive on the second battery?Any information will be much appreciated. Thanks in advance. Wolverine. Big Red 110 CSW
