However, you would usually have it set on 25A to properly charge the 'house' battery - I would imagine. These specs (from the attached PDF doc) show the Projecta IC2500 has a 'variable' output of 2, 6, 12, 25A. It is only because of a NSW regulation that I realised that battery was flat. One cannot assume that most/all vans will be towed on a regular basis and hence charge the battery. Now that I know this has to be done separately I will take appropriate action. Also, if you are new to caravans and the dealer does not explain this, and most don't, your break-away battery goes flat for no good reason. I have never understood why the break-away battery is not charged by the house battery charger. The 240v side is not operational at present. One would assume that the 12v is for when towing and 240v is for when connected to power. On the casing that holds the battery, as well as the usual lights, there is a switch to allow you to choose OFF, 12v or 240v. We never got an information sheet given to us. If you take the cover of the break safe unit the colour coding of all the wires is quite explicit,also if you purchased your van new you should have received an information sheet concerning the breakaway unit which will give you all the information for correct operation. Hi Larry, As a general rule the battery in the breakaway unit is not usually charged by the battery charger in the van.It should be charged however by your tow vehicle 12 volt auxiliary line which is normally Pin 2 and a black wire. I have the +ve connected to the blue wire and the -ve connected to the white earth wire. After a few minutes the figure does not reduce and at times the charger automatically cuts off due to overload.ĭoes anybody know what else need to be done. Logic would have it that there is no way the battery could be in need of 6 or more amps. The battery is brand new, as the previous one when flat beyond salvation, and was put on a charger prior to being installed. After connecting a battery charger which also displays the amount of current being 'dispensed', the meter reads 6 amps, and the 'charging' light does not illuminate. The diagrams refer to it as 'service brakes'. Based on diagrams I have seen, this is the wire that supplies power to this battery and on some plugs/sockets it is identified as 'service'. I have isolated the blue wire (#5) in the socket. I have had an attempt at charging said battery but encountered possible problems. Because of an oversight from the manufacturer, our break-away brake battery is not being charged when stopped and connected to power.
