Hi
Welcome to MHF.com.
Do you turn the switch off next to the Sargent ecu box for the reversing camera and TV sound system. That will draw a fair amount of current in standby.

 

Just about to mention the rear view camera.......that I fitted on mine needs to be disconnected when left for a length of time.

The leds can be seen glowing faintly at night - this drains the battery over time.

 

Thanks DJP & Twinky - we have already eliminated the camera and the switches next to the PSU - all off. I will ask the dealer to double check the actual camera power feed though. The vehicle is still under warranty so I don't want to meddle too much myself at this point.

Agree with this.. The battery on our Apache 700 always drained fast until I turned off the switches near the Main unit...

 

Ditto re turning off ALL switches in the entertainment cupboard and removing radio as that has a light on when engine off.

We also have a solar panel and battery master which do a very good job of keeping our leisure batteries and vehicle battery topped up.

We can leave ours for several weeks and it will start first time. (not usually left for this length of time ).

 

If you need to identify what's drawing the power have you got a multimeter? If so set it to DC amps and connect the meter in series with the battery. You will then see the current being drawn.
The next step is to remove one by one all the fuses until the current drawn is nothing. This will enable you to identify the circuit concerened.
All you need to do then is isolate the relevent bit of kit when you're parked up.

Hi WUFBER, as has already mentioned there are a number of devices that are "on" even when the vehicle is is switched off. As Bob has suggested and think you may have already identified by removing the fuses one at a time it should be possible to identify the source of the drain, but if, as some devices are connected permanatly to the vehicle battery, the alarm and immobiliser this is very difficult to fault find.
If you have acess to a multimeter and we can help by talking you through some checks then please either call us (01482 678981) or send us a PM with your contact details and we will call you back.

Best regards

Following Bob's advice I did some testing this morning with a multimeter. I also reset the EC100 Control panel by removing the vehicle and leisure battery fuses in the EC325 (as directed in the fault table in system document on the Sargent web site). As a result the current draw is now a constant 110 - 120mA, once things have settled down.

When the vehicle is locked and alarmed after the initial surge, as all the systems settle down, the drain reduces to 110mA. So it appears that the fault has cleared itself.

I have tried to replicate it by operating all the various 12v systems in the vehicle but it now appears to be much better.

From talking to people off-line I understand that an X250 Motorhome with a Sigma alarm will normally draw about 100mA. additionally the Phantom takes 12 - 18mA. Therefore 120mA seems about right.

Thanks to Dave at Sargent for calling me back and advising me what to do if the problem reoccurs.
