That will be the cause of the car not starting, its a fusible link and obviously will require replacing. However you still have the problem of the F4 fuse blowing, and you have learnt now not to over-rate a fuse that is designed only for 10A by placing a 20A fuse in its place. Iam afraid you will have to eliminate each circuit on that fuse point individually as there happens to be a lot of components on that circuit. On that particular fuse you have:-
1) Map reading light.
2) Lights on buzzer.
3) No charge warning light.
4) Electric mirrors and windows (If fitted).
5) Radio.
6) Direction indicators.
If you can, disconnect all these systems and then begin to re-connect them back on one at a time, eventually and with a bit of luck you will isolate the problem. Oh and good luck!!!!!!!!
