Ignition Barrel

On closer inspection, it didn't seem too hard to get into to clean it up as it's a little intermittent and temperamental, only a refurbed Vectra column I guess its just dirty.

Removed the Key barrel and undone the special little grub screw holding the switch in place. Don't loose this as it has a locating shank on the end of it.
Delicately and slowly unclipped the 3 clips holding it together, hoping its guts wouldn't open like a grenade.
The contacts were pretty black and sticky, so a bit of Brasso on a pipe cleaner did the trick nicely. (forgot to take a pic before I cleaned it.Putting it back together was tricky. The little clear plastic spacer has a tag on it and fits in the black part rotating 270 Degrees. The wrong way it will only move 90.
I think this is right, as the wrong way it jammed up. lol.
