Battery Puzzle
It's now been parked on the drive for the last week without an electrical hookup and on going to the van this morning exactly the same thing happened again with everything working correctly. The vehicle battery is only 1 month old, I don't know the age of the leisure battery but as seen from the photo the green stripe would indicate that it's OK. I measured the voltage across the terminals and the result matched that of the Sargent display in the van
Would be grateful if anyone can offer advice as to why the low vehicle battery alarm is sounding and possible remedy. This fault does not repeat when on EHU.
Many thanks for any help and apologies for my photo editing skills as try as I may I can't turn the battery photo through 180 degrees

Re: Battery Puzzle
it needs to be taken off Peugeot and put on fiat
check the battery amps are set to what the new battery is
because you disconnected the power it may have gone back to the factory settings and not what you need it set to
the 14.9 volts in the picture was that from mains charge or solar as it should only be 14.8 volts max and at 15 volts will turn off the control

Re: Battery Puzzle
I think there are two fuses, one for the positive and one for the negative.
Replacing the fuse solved my problem so it’s worth a check.

Re: Battery Puzzle
I had similar issue. Turns out battery fuse was blown and high voltage reading is of incoming solar voltage which is higher.Apple wrote:Whilst off grid last weekend my low vehicle battery went off after 2 nights. I checked the gauges and the vehicle battery gauge was showing marginally under 13v, the leisure battery showing 14+ volts. The van started and everything was working as it should.

Also if you have an autosleeper van why have you got a lead acid battery as Autosleeper says they only supply Lithium Ion batteries. See page 9-10 of owners manual.

His van is 2013 so we’ll before the date AS started fitting Lithium batteries

That’s correct but was has AS fitting lithium batteries got to do with his as you stated

It would had been better if you said sorry you made a mistake and was trying to helphandiyman wrote:

Not all problems on different age campers are the same
The charge voltage should only go to 14.8 on mains or solar and at 15volts the control turns off
This is the reason I say on lots of post to fit a mppt controller when the camper has a ec500 or ec700 electrics if not can get a over voltage spike above 15volts and the controller turns off .the people that have said they had this problem thank you as this has helped others to not have the same problem

Turned out that the terminals on the EM45 panel under the offside seat were burned.
I've replaced the EM45 and renewed the plug so all seems to be well now. I'll be looking for signs of overheating regularly now that I've seen what can happen when the leisure battery voltage falls to such an extent that the charge current causes overheat on the fuse panel.
I should have sensed a problem when I was getting messages from the Sargent tracking station that the voltage was low on the leisure battery and the vehicle battery but all seemed normal when I checked at the over-door panel display.

Battery Voltage
Charge it up again and with the battery connected turn off everything in the MH and wait for 2 days then check the battery voltage again if it is still high, switch on each appliance one at a time wait 2 days and check the voltage and keep doing this to find out what is discharging the battery. The vec Battery should not discharge whilst you are parked up.

Re: Battery Puzzle
I am a Boxer AutoSleeper Symbol owner. The Charging system had modified by an "Expert" and could, and did, discharge the Veh battery. I converted it back to original and repaired it. My system is now fine.
Happy Camping

Re: Battery Puzzle
The leisure battery probably has had zero discharge since the last time it was charged - i.e.yesterday on the solar panel. The vehicle battery would have had a small amount of discharge overnight due to the radio, remote locking circuitry etc.
You don't mention the type of vehicle battery.
If it is a flooded lead acid the open circuit terminal voltage will be around 12.6V. A gel or AGM battery will be around 0.2V higher.
Maybe the Sargent is expecting a different type of battery to what you have fitted and it's dipping below the alarm trigger voltage overnight.

Re: Battery Puzzle
To test a battery for its condition needs a battery cranking amp tester and will test the amps in the battery .12.8 volts could be the voltage but the battery may now be only charging half the cranking ampsAethelric wrote:During the day you will be. charging from the solar panel(s). Your leisure battery looks like a fully charged battery (maybe even over charged) on charge. Your vehicle battery looks like a partially discharged battery on charge.
PLAESE NOTE
Just because the leisure is showing 14.9 will not say it’s fully charged it’s the charge voltage from the mains or solar.charge .to test a battery voltage needs to have been taken off charge for a time a let stand

What has been said by this person is no help for the fault with the the electrics the person has that started this post for help
