Hi, I hope somebody may help. I have a Bailey Senator Indiana series 5 2006 van, the problem is the onboard battery does not seem to be charging when on the mains or car. I have checked the terminals with a voltmeter with no charge showing. I have checked the fuse on the fuse board and thats OK. Ia there another fuse elswhere I do not know about or even a relay switch that could be faulty? Any help Please.
Not sure about the Bailey Senator but some in-caravan chargers have a switch to switch the charger on as well as the car-caravan switch. With the car engine running, check that there is a 12vdc voltage across pin 4 (+ve) and pin 3 (-ve) on the 12S plug. This will indicate that the car charging circuit is doing its job. The voltage across the two pins will disappear when the engine is switched off. If there is no voltage there with the engine running there is a fault with the car relay. If the voltage is there but not in the caravan,the fault lies with the 12S plug or the habitation relay (if fitted) or the first fuse as the cable comes into the caravan (usually in the locker under the front seats.
Has a wire become disconnected? Are the connections all sound? Have the battery terminals been cleaned and re-attached? Is there an output from the charger in the caravan? The fact that the battery is not charging from the car or the mains suggests a common component which is activated by both sources such as a relay.
Start at the battery and ensure that the negative cable (normally black) is connected then trace it back towards the source of the charging voltage checking for a sound earth connection as you go along. If that seems to be ok., do the same with the positive cable (normally red) but this time with a volt meter or a screwdriver which will light a small neon if the presence of 12vdc is detected. Immediately you get a reading you now know that the volts are available up to that point. it follows that the fault must be immediately after that point. You may be right about a "relay I don't know about". On many caravans there is a "habitation relay" which, if inoperative, will stop the charging voltage getting to the battery.
You will no doubt appreciate that long distance fault finding is a bit hit and miss. The above suggestions are given in good faith as a starting point to sorting the problem. f you do drop on the solution, please let us know in the form of a post on the Forum. That way we can all learn. Good luck,
My friend is having exactly the same problem with his Bailey Pageant Bretagne (2007 model). When the car was plugged in, the battery wouldn't charge and there was no power to the fridge. Traced the fault to the habitation relay that is built into a board in the consumer unit as it was only when he tapped the relay he could hear it switching.
Couldn't buy the relay separately as it is integrated but local Bailey dealer was able to order the whole board for approx £45.
