Pretty sure there's a 100 amp fuse under the top part of the fuse box.

All fuse seem 2 be OK. When I 1st start the car and leave it running for 10 mins the lights ain't on until I start driving it

Is the main earth lead ok ( bolted to the top starter bolt ) ?
You can use a jump lead from the battery negative to the engine ( air con bracket for example ) to eliminate a poor earth

Does the battery light come on when you first turn the keys and the dash lights come on ?

I will try a jump lead tomorrow. The battery light doesn't come on when I 1st start the car, I I drove 2 work 2day and a the light didnt come on till I was nearly there, which is about a 15 minute drive, normally the light don't come on straight away when I start it, it comes on when I start driving

i would do two new wires from the negative battery terminal, one to the chassis one to the engine , if that does not solve it then look at the output wire from the alternator see if it’s damaged ? have you tested the alternator out put voltage and battery out put voltage so you know 1 the alternator is working and 2 charging the battery
