    Went down to the motorhome today, have not been able to get there for a few weeks but was not too concerned as the solar charger was working well and batteries fine. Central locking wouldn't unlock from the fob so I let myself in using the key manually to unlock. checked the 12v system and both the habitation and vehicle batteries are virtually fully charged - watched solar charger working as well. All the batteries including the vehicle battery, are only a few months old.

    Tried to start the van as I thought I would take it for a run, and there isn't a flicker of life - zilch. Stereo also not powering on, no dash lights, no starter turning over, nothing.

    Where should I start with troubleshooting this?

    First thought was to perhaps buy a new battery for the keyfob but are there any other issues I should check before having to pay ££££ to get someone out to it?

    The van is an Adria Vision on a Renault Master chassis.

    Advice would be greatly appreciated.

    If you haven't disconnected your immobiliser, then the van wont start????? You had to manually unlock the door. So, (in theory), the van still thinks it's in 'safe' mode. ?????

    Possible immobiliser fault.

    Central locking may be controlled from immob module.

    First thought was immobiliser, never had an issue with it before but I suppose it could happen. Its always worked no problems, but I suppose electronics have a habit of dying for no apparent reason. We are on the main Don Amott storage site so I guess the workshop techs could be booked to come and sort it out or I could look for a mobile auto electrician.

    Yes true, but I cannot get the fob to work to disarm the immobiliser and open the door via central locking. Also most other vehicles I have driven, the stereo works even when the immobiliser is armed.

    No harm in trying a new fob battery.

    Possible immobiliser fault
    Or a spare key/fob.
    Could be the existing fob code is corrupt.

    sounds somewhat like the vehicle battery has failed. the solar panels give the impression its fully charged. but when you turn the key, nothing other than a few lights will work

    try disconnecting the panels from the regulator, then remeasure the battery voltage after a few minutes

    Will try that during the week , hopefully its a simple fix but I did see the little light on the fob seemed to be working so not sure it will be that easy to solve.....maybe its too weak to send a signal though, on its last legs. Haven't changed fob batteries in years so could be that.

    Happened to me earlier this year when the van had been sitting. It unlocked ok but nothing on the ignition switch, like yours, dash lights and everything dead. Don't ask me which bit of electronics it fed but when I checked under the seating I found a blown in-line fuse amongst the connections between the original external leisure battery and the second one mounted in the locker. At the time I didn't know I had a battery master on there and assumed the vehicle hadn't been charging from the solar panel. I've since learnt there was one fitted along with the panel last year so quite what was wrong I still don't know. I replaced the fuse and put the vehicle battery on charge since when it's been ok.

    Brand new vehicle battery, installed only 2 or 3 months ago. Fob not opening the central locking. No lights whatsoever on dash when key in ignition, stereo not going on.
    The Adria's Electroblok uses a smart charge type system integrating the solar panel regulator directly to the Elecktroblok and is generally pretty accurate, but its worth a try, maybe I should take my heavy duty jump starter up and see if its a battery issue, but Iwould have thought that a 2 month old Bosch battery would have a tiny bit of life in it.

    I have an Adria Matrix on a fiat with a cobra alarm, on the odd occasion when I try to open the doors with the alarm fob it won't unlock the hab door. I then manually unlock it and use the original key fob not alarm fob to lock all doors, once I have done this I then unlock and lock with alarm fob and it can take several attempts before all doors lock and unlock. This normally happens if van hasn't been opened for a week or two.

    Can't help with the problem, but it is good to see you posting again.

    I would look for a loose battery connection. Assuming the connections to the battery are like most, a clamp onto the terminal and the extra connections are bolted to the clamp. Any one of the wires could have come adrift.

    I would check all the earth wires especially if new battery were all the cables correctly fitted

    Yes, started up all good no issues when the new starter battery was fitted. Access to the starter battery is dreadful in the Renault Master cab, so I got the workshop guys to do it. It started perfectly with the new battery.

    double and triple check your charging system then to ensure all connections are clean, and the alternator is putting out a good charge. I wuld also investigate the electroblok as something is killing the batteries. mind you its not unheard of for a new battery to fail in weeks. get it tested and replaced under warranty
