O Learned Denizens, only my second post to your hallowed halls so please go easy on me.
2010 XF with halogen H7 headlight bulbs. Right hand failed a few months ago and I changed it without incident, apart from cursing the person who signed off that delicate tab on the top, which was pre-fractured of course. So I am notionally capable of changing a bulb.
Left hand just failed, replaced the bulb, no joy. Reading in the manual I see there are no fuses but instead a Field Effect Transistor protection.
So now I am baffled what to do next. Any pointers?
I'm OK with a multimeter but I need to know physically where I am pointing the multimeter and what a happy multimeter looks like.
