little update:
Had my battery tested - reader came up that it was only giving out 375 so ordered a Bosch S4 026 - Replaced the battery - still no main beam
Took the drivers side wheel off, went in through the arch, changed the side light - nice and simple, checked the ballast/connecter, seemed in tip tip condition, no moisture, no dirt, it looked like new. Took the bulb out, looked used obviously but no real signs of damage, replaced with a new 600K bulb. switched the lights on and.... nothing. (side light worked fine).
Have a work thing so only had time to do the one side so far.
Anyone have any other thoughts on what could be the issue.
Relays changed
Battery changed
Bulb Changed
What's next?
In terms of parts, what should i be looking for in ballasts and igniters? Could it be something as simple as a fuse? (novice when it comes to auto-electrics so wouldn't know what to check to be honest).
