Can Anyone "shed some light.."

ThatDoesntLookRight

Evening All,

I have an installation, and need a little assistance:

Client has 6 bollards in a row on a garden circuit, which is digital Time-Clock controlled.

The supply is buried SWA loops which as usual loops in and out of each. The lamp-holders are Bayonet Caps, in new condition, (no loose springs!) and new lamps.

There is a little 4-Amp(?) bladed fuse in-line of the Live of each fitting, these are all checked / new.

There is a confirmed 240v Live to Neutral, And (L-to-E) at each set of pins / terminals, within each bollard; however a lamp only operates inside of one, -the central fixture.

Any thoughts or wisdom?

nb, As part of the process, we've tried new lamps, swapped the lamps around, (still only the one same bollard lighting up) overridden the time clock, and verified Neutral connections through-out. The current at the lamp-holders also seems consistent at each fitting.

Many TIA

    Try a different light or temporary lamp holder to the supply of one of the bollards. Also I had an incident once where the part of the lamp holder that holds the lamp in place wasn't correctly lined up with the pins so they were not making contact . I have also had times when the contacts on the back of the lamps don't reach a pin or pins but sounds unlikely on several fittings. I would definitely try a temporary light first to eliminate a supply issue.
