Man tge 2025 batteries constantly going flat

[Raul a/3]

I can't edit my post #14 anymore, but another drawback of the Victron Invertor trickle charger is that is can only load with a copy of the profile as used for the LB and as most SB's are AGM they need another charging profile. I'd not use that due to this.

That is another misunderstanding of the auxiliary charging function, there is no charging profiles on the auxiliary pin, only a single voltage output to maintain the SB, not to fully charge it. Its only a maintenance charge to cover low draw or self discharge. And it works wonders, my van SB is 8 years old and still going. Maintained by multiplus aux pin.

Right, I stand corrected. Can a mod change my faulty posting to not be wrong?
Thanks!

My 2025 MY TGE does the same with the coolant pump running. I generally lock and listen, if the pumps running unlock wait 10 seconds and lock again and it stops running.

Morning buddy thanks for this
So it may not be a fault then if yours does the same ,although it makes no sense really does it .
I understand the pumps will prime on opening but to keep running is weird you would expect them to be timed and shut off automatically if the vans not started,,
I had it bk to MAN and they plugged it in no faults found,
But said they would need to keep it there a few days so it can be checked when the engine is cold??
He did mention that when a vehicle arrives at a dealership in transport mode they have to plug them in while doing the pdi to obviously set the van up from fresh for the customer,and some dealers don’t always run the full set up ?so if it’s cut short it can cause some issues??
He ran a full dealer reset on my van he wasn’t saying that’s the issue he just said it’s something that he has come across a couple of times?
So time will tell.
Really appreciate the reply buddy Thankyou

No problem, my Wife always makes sure it's not running when we leave it. She drives me crazy!

So went to drive off this morning from our night away, and click click click click. NOOOOOO
Had my booster with me but did nothing.
Thankfully, the van next to us volunteered to jump us.
Once I disconnected main battery from LB, we managed to get the van started. However it seems that the leisure set up is draining my main battery. Found nothing on original van that would drain battery once it is locked and disconnected from victron kit.
Seriously considering a dead man’s switch on the main battery.
Any help or advice would be greatly accepted.

What does connect your starter to the leisure?
Is it a split charge?

 

[mike12314]

I have the Orion 12/12 -30 DC/DC charger.

I have the Orion 12/12 -30 DC/DC charger.

Well, Orion surely does not allow back flow, certainly that is NOT the path you are discharging your starter. Look elsewhere, and invest in a DC clamp meter to trace the draw.
You also need a battery master or Abelmail to trickle charge the starter from the leisure.

 

[mike12314]

Have a clamp meter. Will check again tomorrow.

 

[mike12314]

Leisure said 51% capacity when connected to main, flicked the breaker between them (I installed it between Orion and main battery), and leisure jumped to 100% capacity

 

[Raul a/3]

Also check continuity of the negative path, all the way from alternator to battery, and battery to chassis. There is a earth strap left hand side engine bay looking in, that serves engine to chassis. Also battery goes directly to chassis. Eliminate any possibility of bad connection path from alternator to battery. Also a voltmeter for the starter will give you a idea how the SB it performs, if anything discharges it, it will show. I have a permanent voltmeter display, plugged in the 12v socket in the cab.
That tells me when the alternator is active, and when engine is off, it shows the battery master maintaining the starter from the leisure.

You not telling everything, or you not explaining it well. Info in drabs does not help.
What tells you the starter is at 51% SOC ? And why you linking starter and leisure together? They should NEVER be directly linked.

 

[mike12314]

Sorry. My mind is everywhere. Victron screen says LB at 51% when connected to SB via Orion.
LB @ 100% when not connected to SB.
Didn’t measure SB voltage
I have my work cut out for tomorrow morning.
Thanks for assist.

I must admit to doing something very silly with the configuration of our Victron Orion XS and managed to totally flatten the SB overnight. I can but assume that the LB (Roamer 230Ah) was quite low and the Orion was incorrectly set-up so that it did not cut off at low SB volts trying to charge the LB.

I needed a jump start and long run to charge both AFTER I had returned the Orion to default lithium settings. I have no idea what setting was wrong as I now have the Orion ser-up to Roamer's recommended settings and had no further problems although I do have an Ablemail AMT unit installed as well.

 

[mike12314]

I didn’t set up my kit. It was set up (apparently) by Callidus before dispatching.
Time to check some specs me thinks.

I have my lock out voltage on Orion set at 12.5v and never seen a draw from SB to leisure. And you should NOT set orion by voltage sensing and engine detection, with a smart alternator. Use a D+, or a simulated D+, or even ignition live with a switch. I use a ignition live with a switch, default off, and only turn it on if LB is low and no solar. When I turn the switch on, the Orion is active, also I turn the stop start off; that way gives me a reminder that I have the Orion on.

Definitely going to leave it disconnected from now on, unless LB is low. I’ll check all my settings in the morning.

Yes, mine is connected to simulated D+ (ignition live).

Your advice to press the lock key twice stops this pump under the bonnet from running strait away on the second click your a genius!!!! how on earth did you find this out???

I also moved my Clayton feeds from the starter battery it now goes to the junction box behind the 2nd battery and up until now it dare I say it the starter battery is mostly above 12.6 when I check on the tracker app that I’m hoping is pretty accurate
