I have been monitoring an electrical problem on our N & B Arto 74 R 2012 for a few weeks & I'm looking for a auto electrician who I can visit or is mobile within 100 miles of York who is familiar with N & B/Hymer electrics & CBE components. The issue I have is that there is a difference between the leisure battery voltage displayed on the control panel & the actual voltage measured by a multimeter at the battery terminals. The control panel is a CBE PC320 & I have tried the recalibrate function but this doesn't resolve the problem.
Any recommendations of an auto electrician would be welcome.

do you have a solar panel? and if so where is it connected?

All control panels meters are notorious for being far less than accurate. Forget the actual reading and simply use it as YOUR gauge and compensate.

Hi All, thank you for your responses. The panel isn't contacted to a solar panel.

The voltage difference varies between 0.5 -1.2 volts. Unfortunately an incorrect reading of this magnitude impacts on the charging of both the vehicle & leisure battery.i.e the vehicle battery will not charge, when on EHU, until the leisure battery exceeds 13.6v
I have a local auto electrician visiting next week & so I'm hoprful he may resolve the problem.

My Hymer (2014 b680 Starline) only delivers a float charge to the vehicle battery when on EHU. The display tends to show whats in the circuit at that moment, less of course whatever is using the 12v. When we ran the recorder on 12v the display 12.2 on the leisure or the vehicle batteries, not at the same time! When we used the inverter to drive the recorder the display showed 12.7 volts. Just use the display as a guide and save your money.

Surely there will be a difference at the battery direct due to resistance in the circuits and drain of components ?

How accurate is the multimeter and is the gauge right and meter wrong ?

The control panel uses electric and may be other stuff in the background.

The charge to your vehicle battery will be via a CBE CSB2 which only allows the charge when the leisure batteries are over 13.6v.
