I’m sharing this issue in the hope that somebody may have an insight. I think that there are too many unknowns and imponderables for some considered advice, but I am hopeful that somebody might say “I had the same problem…”
My vehicle is an Adria Coral, and the electrics are managed by a Nordelettronica NE237 and associated control panel NE166, from 2015. I recently replaced the lead/acid battery with a LiFePo4 one, and had the Nordelettronica NE237 Control box modified by the excellent Apuljack Engineering company so that the battery received the voltage it wanted; similarly I flipped a switch on the Solar control to the Lithium setting.
Driving along, the NE166 display sounded its alarm, and when I was able to stop, I could see that the charge warning light was on and the ammeter was showing a charge of 15A. On another occasion (same alarms) the ammeter was showing only 0.1 amp, but it was oscillating between charge and discharge. Once the system had gone so far as to shut itself down.
I shut everything down, and on reawakening it all was well.
In order to establish whether the alternator was at fault I bought a simple device that showed what was going on. It showed a normal output from the alternator.
I disconnected the solar charger.
There is no discernible evidential cause, the fault seems to occur randomly, different battery states, different time on the road. The battery is healthy.
It doesn’t happen when connected to 240v.
Since it was last all working happily, two things have changed - the new battery and the modifications to the NE237. The problem seems focussed on the charging side of things.
I did the obvious thing and took the MoHo to Apuljack, and they have been unable to replicate the fault, so cannot fix it.
I think my only course of action is to live with it, and meanwhile try to gather evidence. I hope there may be some sort of data-logger that I can easily insert into the system. Anybody know of one?
Naturally I am concerned that whatever is malfunctioning could be causing damage.
Given all that, does anybody recognise the issue, or have an inkling where the fault might lie?
It would be nice to think there might be a solution, somewhere.
Thanks for at least reading this!!
