Fiat based motorhome engine battery disconnect. (1 Viewer)

[Dorset Diver]

I need to know if I can disconnect the engine battery terminals on our 2015 fiat based MH without causing a mass of problems. To be specific can anyone advise if a) the battery be disconnected without causing a mass of problems need resetting of this that and the other, and b) if it can what should be disconnected / switched off prior to so doing? For the moment I would just like to check the battery fluid levels but can't do so because various bits including connectors and terminals are in the way.
Thanks in advance for your help.

Changed the battery on ours 2014 last month only thing I needed was the radio code

Ignition off & disconnect negative terminal first, reconnect last, you'll probably need to reset the radio code & you'll probably set off any alarms you may have fitted.

to save loss of radio code, pp3 battery with suitable connectors across the leads as you disconnect,

I've disconnected an auto trail and a burstner and no problems even the radio code didn't need re-inputting

Thank for the idea, does the PP3 have enough oomph?

I watched a lad from Halfords change a battery in my daughters car and he used a couple of pp3 batterys taped together with clip on leads .

Not specific to Fiat but my advice with any battery disconnect is to switch off ignition, remove key and then have a cup of tea before disconnecting, this allows any EDU or control module to shut down fully. Not keen on keeping any live feed across the leads as it can give feed to other components better to recode the radio. I know many of you will think l overdoing it but I've seen too many problems caused by just quickly disconnecting l only need to be right 1 in every 100 times to save someone a small fortune. Compare the computer power of a 2015 Ducato with the rocket that took man to the moon and you will see why vehicle electronics need to treated with huge respect.

If it has a tracker fitted it will set it off and you will probably be getting a call from the company monitoring it.
