Hello to everyone out there,
Just came across a bit of an oddity on our 2006 Elddis Knightsbridge (Avante clone) which we purchased earlier this year. We have used it quite a bit over the time we have had it but never realised until yesterday that the on board battery is not recharged whilst towing. The thing that gave the game away was using the motor mover to put the van on the hitch at our last site. Now on our previous van, also an Elddis but a 1998 Jetstream, we would arrive home from the same site and on taking the battery home find it was almost fully charged, needing less than one hour to bring it up to fully charged. This time the battery tok some four hours to fully charge. An inspection of the owners handbook showed no connection to the split charge circuit on the car, although the 12 volt fridge feed was present. Not believing the book I took the covers off the 12 volt system and using a multimeter proved that this was indeed the case. So now I have had to design and build a suitable circuit to get round the problem. Does anyone else have a similar experience? Because if we had been going to a non hook up site we would have arrived with only a partially charged battery. Very strange! |

In my experience most split charge systems are pants, also even though the 13 pin connector is common, there are still variations, if you have made your own then stick with it, Rick

The only answer is to beef-up the feed to the battery/fridge supply by fitting extra (min. 4mm2 section) feed & earth cables direct from the car battery (via 25A fuse) via a designated 7 pin system spliced into the existing 'van loom. By doing this I managed to increase the voltage at the fridge by over 2v, from a useless 11.5v to an outstanding 13.7v! Needless to say the fridge actually works on 12v now. Charging my battery was not a problem (roof-mounted solar panel)but this mod. can only have improved it. |

You have hit on an old thread there mate but nice to know you are still looking in, Rick
