Aligning a BC Unswitched Lampholder

After installing and wiring your lampholder you find it is not working please check the quick signs of a blown light bulb etc.

If its not the light bulb for example please read the following help file about the alignment.

Some of the un-switched lampholders need to have the 3 parts lined up or the lamp will not work when connected. Please make sure these parts are aligned.

There are indents on the side of the 3 parts and these must all line up together.

When fitted you can check like this. The 2 slots of the lampholder will be 180 deg. from the 2 pins. This is what you need to ensure the contact of the lamp makes contact to the lampholder.
