Twizy 3 Beeps

So I used my Twizy earlier to my essential travel for the day, came back, left it for a couple of hours, thought I better move it to charge it, 3 beeps, SERV, STOP and the 2 battery icons. OVMS showed more errors that I hoped:

Have pulled the 12v battery for a while and tried again, still the same issue. This looks like the SEVCON has gone nuts, any ideas?

Thanks

It gets better after trying another battery pull:

You are charging the 12V before re-inserting and is it holding a good charge?
Have you checked it when you removed it?

Yes, the battery is holding about 13v which I know is a little high. It’s a new one too.

Is this a Sevcon or instrument panel fault?


I’m having an instrument panel issue myself…and it looks something like this…
