Good evening all - bit of a puzzler here and any guidance from the learned forum members appreciated...
Battery OK but car TOTALLY dead electrically (ingnition key fob does not even turn in lock or make the usual click)! !
Happened briefly twice before but eventually started ok.
Suspected a loose battery terminal but found it tight and secure, disconnected the battery nevertheless and reconnected the terminals but noticed there was NO spark (like the one you get normally on connecting a battery to a car with various live consumer units like alarm, radio memory etc).
Out of habit! Checked security of all visible relays and fuses under the bonnet and boot and all looked ok.
Connected a jump battery and there was not the normal associated spark at the contact areas which leads me to believe that the positive wiring within the car is somehow electrically disconnected either by a stuck relay or some other misbehaving 'clever box'.
Resorted to momentarily touching the earth lead to the battery terminal several times until the 'proverbial' spark reappeared and hey presto, all is almost well and the car started on the button but with the interior lights flickering and ABS, BAS and OIL LEVEL lights on - flickering lights diminished on RPM increase but other lights remained on.
As this happened at a friend's house, we are taking the car to my place while all seems working.
One thought that springs to mind is that once the car is running it is fed electrically by the alternator (flickering lights) with the battery STILL isolated as the cause of the original problem..
Anyway, would appreciate any thoughts on this and in the meantime will attempt to get the car home and report back in a while
Many thanks
