My Spring controller, is showing 14.7 volts from the leisure battery,(without van engine running), the pump is also surging, does anyone know what will be causing the issue ??

Thanks in advance Phil :)

When your pumps are running and the engine is off does the voltage reduce at all?
If it doesn’t, then mayb it’s a faulty reading.
Also when you say surging? What does the controller read? Is it DE? PS?
That might just be a setting issue.

What does it read after 4 hours of complete leisure battery rest? If after the length of rest, is the pump still surging when switched back on?
My old 04 plate Citroën Relay charged my leisure battery using a split charge relay at 14.6v. My current Peugeot Boxer alternator charges at an output voltage of 13.9v.
New model vans that have smart alternators, are a whole new topic for discussion depending on make and model.

Very good points cheers,
The pump was surging during the day, I checked the reading when I got home and it was 14,7, did not have time to explore then, This morning its now settled to 12.7 My initial thoughts were debris from tank clogging the pump, just a few jobs later in the day and will have time to explore further.
Van is Citroën Dispatch circa 2015, has a split charge relay, solar panel & charger and no smart alternator, has been pretty reliable so far TBF but as you can tell a fair few electrical possibility's.

Hi Phillip
The Controller has a Volt meter and we are measuring volts across the battery terminals. As such the controller will display the volts it measures at the battery.
Is the battery also linked to the Solar charger ? It is possible that higher battery voltage reading was down to the charge from the solar panel over a short period.
As the voltage later dropped to 12.7V this would suggest the control volt meter is reading correctly
Cheers
