Battery monitor light possobly faulty (1 Viewer)

Hi All
My battery monitor light on the central Truama unit is only showing 1 red led, the bottom of the scale. The battery seems ok 12.6v before I hooked up the charger but after 10 mins 14.8v. Took it away last week no problems but symptom was still there.
Is this a faulty central unit and if so what can I do to repair it?

Thanks

Does it also have a readout in the panel above the light bar? If so, what voltage is shown there?

No it doesn't Geoff.

Then all I would suggest is measuring the voltage at the back of the light display and compare it with whatever lights are showing on the front.
