PMS 3h - Power Management System
- Thread starter MJB67
- Start date
Not sure on how yours is wired but I have a PMS3 and in the ‘off’ position, neither battery is connected to the leisure side and neither should discharge due to the leisure circuits. I leave mine ‘off’ for weeks on end.
On ‘car’, mine is using the starter battery under the bonnet to power the leisure circuits.
On ‘van’, mine is using the leisure battery to power the leisure circuits.
Any power drains from the starter battery circuit - dash cam, fridge, USB chargers etc?

thanks for the reply. So when hooked up you have it in the off position?

There must be something wrong with how mines set up then.
I’ll have to have a stewards with the company that installed it.
Thanks

Hi, I have the PMS3 in my T5 and just flicking through the instruction manual... It says it should be in the "off" position when driving. But then my fridge isn't on? Surely I should be able to have my fridge on while driving to save my food going cold? I'm new to this campervan scene so I'd be over the moon with any help/advice. Thanks!

Not sure how yours is wired, but my fridge is independent of the rocker switch. I can run the fridge off the leisure battery regardless of the battery position switch.
I do sometimes drive with the power switch on even though it says not to. I do it so the kids can use the USBs and lights to read while we’re travelling.

Hi mate, thanks for the reply.
So does your fridge have a separate on/off switch then? Mine just comes on when the PMS switch is on or it's hooked up to the mains.
When you drive with yours on, is that on "Car" or "Van"? Sorry for the 20 questions! Haha!
Mine has an independent switch on the wall for the fridge.
On mine, the ‘car’ battery is the starter battery under the bonnet and the ‘van’ is my leisure battery. I tend to only use the ‘van’ setting to avoid draining the starter accidentally. I labelled mine ‘starter’ and ‘leisure’ with a label printer to make it clearer.

Ah OK, that's interesting.
I'll have to have a look at how my fridge is wired up. So when you're driving with the switch in, you have it on the van/leisure battery setting?
Thanks
I use that setting on mine. They do advise not to though. It does depend on how yours is wired. Worth speaking to the converter?
There’s a manual here if it helps.
I also have a DC-DC charger on mine, as the converter initially used a simple relay, which doesn’t work for T6s due to the smart (variable output) alternator.
