this is the reason why i ask:
last week my car was driving fine. got home turned the car off as normal (by the key). when i next went to start it i had no power at all not even foot well lights, hazards light nothing nada zip. so i decided to jump start the car. started first time. went for a drive. all inside electrics were working fine. by this time it was getting dark so turned on my side lights and the whole car died ( on a roundabout i might add!!!) i had nothing, again not even hazard lights.( so i was getting a few suggestive comments from other drivers). so pushed it back onto a verge. got someone out to jumpstart it again. started first time, got it home. switched it off. 5 secs later tried to start it and again nothing. so you would think that the answer would be a knackered alternator or battery. changed both of those the following day. still had the same problem. but again would start first time from another car by leads. (even without the other cars ignition being on). so i was told that some cars have a fusable link hence why i asked. but definatley can't find one.any ideas at all!!! thanks for reading
