    I have a three year old Autocruise Stargazer. Everything is great except the control panel. It took me two years to get it working properly via the supplier, manufacturer, and the makers of the panel itself.

    Now it seems to be the most wasteful device on the van. I thought I had a problem, so three days ago I got a local battery specialist to fit a fully charged heavy duty battery. In less than 72 hours, with the control panel switched on, and no other devices of any kind in use, it has reduced my battery charge level to 70%. I don't know how to convert this into ampere hours or what ever.

    Can someone advise me if this is excessive? It certainly seems like it to me.

    Thanks.

    How sure are you that something is not running in the background ? Like a charge going to the starter battery.

    On the face of it is excessive but is it accurate ? I would not believe the accuracy of such a panel until I'd verified it by meter.

    Charge fully, 24 hrs, measure voltage. Should be 13.6 plus before you switch off the charger.

    Now measure voltage one hour on then every few hours and report back.

    Hi Brocsman
    Could you clarify what manufacture of electronics you have in the "Stargazer".
    If its "Nord electronica" the chances are that the relay / fuse panel has a fault in it.Even with everything in a dormont state it could still have a current pull of around 4.0 aph (common fault with "Nord" equipment).This will significantly reduce the life of the leisure battery.
    If you put a amp metre on the battery terminals of the leisure battery you should be seeing readings of about 0.04 aph.
    If you need any help you are more than welcome contact me.

    Regards

    How do I find out the manufacturer? The name I was given was three initials, like SEM EMS, something like that.

    I have an Autocruise and I find the panel very helpful in the information it provides, but by fitting a different battery you may have upset it. :Eek!:

    I'm sure I remember that when fitting a new battery there is a sequence for setting up the panel to the new battery as it may be different to the original equipment.

    If you have the original handbook it is explained under "Connection of Services".

    I would also agree with Brian, check the batteries themselves as these control panels may not be perfect.

    EDIT: Just checked mine & when it switches on it says it's a "Kingass" system. The initials EMS could mean Electronic Management System.

    This is what I did over the weekend. Start, battery 100%, voltage 13.something. Day 1 battery 90%, voltage 12.6, day2 battery 80%, voltage 12.3, today battery 70%, voltage 12.1. Only the control panel switched on. No link to the vehicle battery as far as I know. (I'm a long way from understanding vehicle electrics).

    I've had it in the dealers for a week and they tell me there is no fault on it. It should be drawing 0.4 amps. Would that run down the battery so quickly?

    Just to avoid confusion, he's never going to see aph on a meter. You used this twice so not a typo.

    He will see mA ( milli amps or thousands of an amp ) or A ( full amps ).

    If everything is off I'd be expecting 50mA, which is 0.05A or less. Greater than this is poor design in the electronics. A good designer can get standby current below 1mA.

    =======================

    While I am typing. The original post say loss of 30% charge in 72 hours. That makes 10% per day. Assume 100Ah battery. So 10Ah has gone missing in 24 hours. Divide by 24 hours and we get a drain of 0.4A or 400mA. That's way too high if in standby.

    0.4 amps is a big drain.. , over 24 hrs that is 9.6AH .. 72 hrs = 28.8AH

    An 85AH battery will be all but flat in five days.

    Either the dealer has the wrong info or knows nothing about electrics ,..

    HI Brocsman
    We believe you have a "Sargent" system within your van.
    Its very difficult to try and diagnose an electrical fault without
    seeing it.
    Our advise would be to get ALL the "Sargent" equipment checked out as like the "nord" equipment its unfortunatly not uncommon for these types of units to get a fault like you are experiencing.

    Regards

    I posted my sums before seeing this. Both numbers agree.

    Well if that is "normal" it's a devastatingly crap control system.

    If the dealer said that was acceptable I reckon he's as crap as the control panel.

    0.4A 12V = 4.8 watts. Does not sound a lot but 24/7 it is.

    Is there a backlight on all the time on the panel display ?

    We were wild camping in Scotland, got talking to woman next door she said they would have to go home early because the heating had failed. I poked around, had to repair a fuse holder she had damaged on the Truma. Then I remembered the old advice, power down the control panel. Ripped it off the wall, unplugged. Plugged. BINGO, heating. Ridiculous not to have a "poke pen in a hole" reset switch. Says a lot about the designer.

    She tried to stuff a load of notes in my pocket, silly lady.

    I've established that the control panel was made by a company called MES, a British company, but I can't find any contact details for them. Does that ring a bell with anyone?

    Yes, it's backlit most of the time. It goes out at 8pm.

    If I need to get all this checked who do I go to? My dealer doesn't seem to know anything, and I've failed to find any trace of the people who made it (I got a phone number, but it was disconnected).

    I'm in Shropshire.

    Thanks

    Oops, you've gone read only, hard to have a conversation now.

    Didn't know this was a subscription site! I've been lured into joining.

    Now where were we?

    Gotcha :BigGrin:

    Not very far. 4.8W could be an over generous back light though 150mA is enough normally. It would be interesting to measure when on then after it goes off.

    Can't help with MES, let's hope someone else knows them.

    How about taking some good pics and posting them, might jog someone's memory, might turn out to be a different make re-badged.

    I'll get on to it in the morning. It's getting a bit dark now.

    Thanks all.

    Easy answer, just get on the phone to Glenn in the morning and have a chat to him, we don't charge for advice!

    01-580-883061 is the direct line to the workshop.
