Have several voltmeters at home so will check when I get back, did my anxiety no good when I realised I had taken the jump leads out Of The frunk for the other car last week..
Leading evidence: 'Check when i get back, did my anxiety no good' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check when i get back, did my anxiety no good' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

How accurate is the voltage gauge?
Took a trip today and since having alternator issues on another car was watching the gauge and it was only hovering over 12v, dependant on how much stuff I had running. not got a voltmeter in the car to check what im actually getting, but what does your voltage gauge read ?
Not very accurate .. it might indicate a fault though if on 12 volts .. buy a cheap volt meter ( £9 ) and check at the battery just in case .

Thanks guys, it started again fine last night when I went out for dinner, I was having anxiety issues after being stranded last weekend driving the heritage vehicle with duff electrics.

Mine reads around 11.5v when engine is not running (my battery is over 6 years old and only an S3) and up at 14v when running.
As a quick easy check, pull up against a wall in the dark, switch your engine off, put your headlights on. Start the car and see how much brighter they go with the engine running.
So took some readings as soon as I got back, the voltage gauge reads about half a volt lower than it actually is.
Measured with voltmeter, Hot, when I just got back after 2hrs on the motorway, at the battery, 12.5v engine off hood open. Just started 12.6v hot, 12.7 back in the engine bay off the jump terminal. That's not charging though at that voltage, but is it a clever system that senses when Batt needs charge?
Cold this morning it read 14v just after I started it up from the dash gauge which held for a minute or so before dropping to 13.5 ish. Later in the motorway it was reading about 12.5 on the dash, but dash reads about half a volt lower than what's seen at the battery.
Just seems a bit weird? Not run out of electricity ever but it's not a new battery by any means and it's usually sat on a trickle charger during the week
Car hot / running , headlights on , main beam on .. fog lights on radio .. heated seats .. anything electric ..
voltmeter on the battery and not the gauge .. if below 13 volts then your alternator is on its way out .
Cold / hot and a faulty alternator will give different readings .
checks are always done via a separate volt meter .
So finally got resolution on this one, had the alternator changed and it now puts out a solid 14volts on the dash gauge all the time when the engine is running. It did eventually kill the battery as the alternator was not charging it when it started to give up. Having it on trickle charge kind of masked the problem for ages.
