I am a little confused on this one - it must be something simple - but beyond me.
Low beam on the drivers headlight doesn't go.
Other side is fine, both side high beam is fine.
Replaced lamp - still not going.
Got the multimeter out - shows 12volts where it should. Tried 2 different lamps on it.
The only thing I can think, is that at some point when I have had the dash out - I have accidentally shifted around the cabling at the back of the switch - but if that was the case - why is the passenger side going?
I am a little lost - any ideas - directions to look?
Many thanks.

Re: Scratching my head - Headlamp issue.
The wire carrying current to your dipped beams has to split somewhere near the front of the engine bay between the two lamps - find the connector block and check the connections there.
Re: Scratching my head - Headlamp issue.
To clarify - I have measured 12volts at the connector - I will check anyway though - becase I realise that 12 volts but no light doesnt make a lot of sense.

Try it with the bulb from the working side so you are sure the lamp is correct.

Re: Scratching my head - Headlamp issue.
Volt drop on the supply cable caused most likely by a dodgy connector block. Unlikely to be the earth as the main beam works ok. Despite low beam voltage being present once a significant load is applied it is enough to cause the problem. Mulitimeters have a habbit of missing this point as they don't load the circuit Chances are the connector block on the inner wing is the issue.

Exactly the type of suggestion I was after, and something I wouldn't have figured out myself.

Re: Scratching my head - Headlamp issue.
Had a much around with the connections in the engine bay today - and viola - lamps back on.
Will replace the connections.
Many thanks!
Will replace the connections.
