Default Car's Dead!!!!!!!!!!!!!!!!!!!!

So, started the car the other day just to keep it ticking over as it were, all good.
Went out today to do the same and before starting, I noticed the fuel gauge needle was pointing to full That's before I'd put the key in. Something's not right I thought. Put the key in & turned to ignition on, as I always do, to let the instruments do their dance & nothing, just a battery light & alarm went off. Turned the car off then back on again, same thing. First thought flat battery, so I put the charger on for a couple of hours. Fully charged, but same thing. Didn't try starting, just took the battery off & took it inside for charging.
Now, before I put it back on again, any ideas where to look TIA

Knowing it seems to be a common theme with batteries on 75s/ZTs have you tried a good battery?

It seems apparent that batteries seem to fall off a cliff when they could be ok one minute and dead the next, having experienced it twice in the time I have had ZTs (and not with any other car I have known)

It may be charged with 12v but not have any current capacity. Can you put a voltmeter on the battery when it's on the car and see what happens when you turn the ignition on or attempt to start it, it should stay around 11 - 12v but if it drops down below that then it is probably dud.

Battery is showing 13.5 to 14v but, it is a few years old now so you may be right Thanks

Oh dear, it's chromium poisoning by the sound of it

I will have a socially distanced drive down tomorrow and suck air through my teeth and tut a bit, and if that doesn't work we'll thrash it with a branch.

Professional repairs such as described, will require coffee and biscuits though

Sounds like the battery to me t- try the voltmeter tomorrow to see if you get over 12.4 at rest - if not a new battery is in the offing.
