| + | [title] Bend contact to correct position |
|---|---|
| + | [* black] Image shows electrical contacts in stand. The green arrow (easier to photograph) shows the good bright copper contact for the outer ring and the red arrow shows the position of the smaller deeper contact for the inner ring (difficult to photograph). |
| + | [* black] The contact should be positioned about half way into its gap. The contact on the inner ring did not protrude far enough into the gap, so only made sporadic contact causing arcing. |
| + | [* black] The second image just shows how a small screwdriver can be used to bend the contact into position (with the mains power disconnected of course). |
| + | [* black] If arcing damage is severe on both the ring and its contact, it may need to be cleaned eg using contact cleaner or very fine abrasive. This fault was caught early, so the damage was not great and no cleaning was required. |
