I would put money on your battery being discharged too much.
Don't know what reading you are getting, but it needs a good charge to turn over a MB engine.

I'd put the battery on charge overnight and try again tomorrow.

Had good quality jump leads on commercial vehicle ones so battery ok

If the battery is good, why did you need jump leads?
Have you charged the battery at all since your jump start?

Hello I used jump leads to keep voltage up there is still no power to central locking interior lights or ignition switch dash does not light up when you open the door ? Help needed I have a merc starbox that wont even talk to it due to no ign
