T6 Won't Start After Insulating And Sound Deadening Rear

[Surfer]

Took the old inside van panelling off the rear drivers side of my t6 LWB van today. Covered in sound deadening then insulation and put the panels back on (temporary until I carpet and replace with fitted panels)
Notice the rear light cluster flickering. Checked the dash and when I turned ignition on the dash lights flickered but no power. Then they went off.
Took the rear panels back off to check I had not damaged any cables but can't see anything untoward. Didn't create any new holes just reused the ones already there to fix the panel back.
The only cable I touched was the brown earth one but didn't disturb it or the ones at the rear of the light cluster just gently pushed some insulation into the cavities.
Battery on charge now just to see if that helps.
Any ideas??

1st guess Is flat battery....

You got a multimeter to test voltage?

Charge or jump start and re-test....

Thanks for the replys. Just tested with a multimeter and down around 6v

Yep. Totally flat..

What's your charger rated at?

A 5amp charger will take around 20hrs to charge up
..

Best to use a proper multi stage AGM charger...

Or jump start and keep driving . . . . Again the engine will take about 5 hours to fully charge...

So no quick 20min charges..... it will need a good proper charge now.

Managed to get it jump started. Drove for an hour then left on trickle charge. Ordered a good ctek charger.
Thanks again for the replys
