Dear all,
Just wondered if anyone could solve this puzzle:
Today I changed the headlight bulb on my car. It all worked fine when fitted, but then -
When I took the ignition key out I noticed the headlights stayed on (I've had the car 10 years - they only work with the ignition key in).
I then tried to start the car and there was absolutely no cranking from the battery at all.
Checked the voltage and it showed 12.6v or thereabouts.
Tried to start again and no joy.
Noticed that the voltage dropped to 8.5 on turning the ignition key on, but absolutely no sign of the car trying to start at all.
Tried to turn on the headlights and the main beam (the bulb I changed on one side) were dead on BOTH sides of the car!
Key fob operated locking also seem dead (but battery shows back to 12v).
Checked if I broke, disconnected any wires on the headlight cluster but they seem to be ok.
Lighting and ignition fuses are both ok.
Not sure if any members would have any idea what the problem was.
Thank in advance
