So I've replace the bulb, and I doesn't want to turn back on, I've changed the bulb to the one that I know works to rule that out so its not a faulty bulb, I've checked fuses for the head lamps thinking there may have been a power surge, there both okay.

Really at a lost cause with this one, I checked for power at the fuses and they are getting power, however I couldn't check for power at the headlamp as it was only with a test light.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hey all! I had a blown DS2 bulb on my 52reg 986 yesterday, and when I say blown I mean I have been left with shattered glass in my head lamp. So I've replace the bulb, and I doesn't want to turn back on, I've changed the bulb to the one that I know works to rule that out so its not a faulty bulb, I've checked fuses for the head lamps thinking there may have been a power surge, there both okay. I've also checked the contacts at the headlamp plugs and there both ok. Really at a lost cause with this one, I checked for power at the fuses and they are getting power, however I couldn't check for power at the headlamp as it was only with a test light. Has anyone come across this before? If so any points in the right direction would be greatly appreciated! Keiran

POST 2Original post

Have you tried swapping the ballast from the good headlight into the one that isn't working? There may be a fault in the ballast on the headlight that shattered, so don't use that ballast on the other headlight until you have assurance that wasn't the cause of the problem. Swapping the ballasts is just a matter of removing the the fasteners that hold them in place and then sliding them off. Cheers,

POST 3 / ORIGINAL POSTEROriginal post

Thank you! I will give that a go as soon as the rain calms! Keiran
