Originally posted by rob_k20d However, yesterday, they suddenly stopped working. So I assumed the battery had simply ran out, so I took it to a shop and got some replacement batteries. With the new batteries, the lights seemed to light up once, for about a second. Since then, however, I haven't been able to get the lights working.
There are a few areas were a certain amount of friction contact is required to make an electrical connection.
Firstly, check to make sure the selector dial is not loose. A spanner ring holds that down and a sizable wobble will not help matters.
Secondly, the upper shell should not be loose... due to missing screws or damage. A set of blade contacts are hidden just behind about where the "ME Super" name is located and any trauma will render that dodgy.
Lastly, as boriscleto hints, over time the camera will have oxidation and decay of certain components. A good CLA (clean-lube-adjust) may be in order. Few ME Super bodies survive this long without some sort of cleaning.
