Hi

I got the dreaded battery warning light a couple of days ago and yesterday noticed the stereo in low power mode, althgouh this appears intermittent.

Using the system check voltage is reading 11v both before and after ignition/turnover which seems horrendously low, no?

Battery is about 6 months old. Everything else working fine otherwise. Have seen others on here with similar symptoms. There's no suspicious smells from under the bonnet. Will an ECU reset be worth doing or is it likely to be a new alternator? Any ideas?

Take it to Guava in Guildford or Rovertune in Reading and get them to stick it in the diagnostic......? * Current: 2024 D350 Defender 90 on coils!

I'd get standing charge and alternator readings with a proper multimeter and go from there, but if your saying the screen reads 11V with the engine running, then it certainly sounds like your alternator is dead.  Visiting from DISCO3.CO.UK
