[Leica] Leica MR4 battery replacement

[Douglas Sharp]

Hi Gerry,

If you do decide to go this way, the following is 
important:


    MR-9 Adapter and Leicameter MR.

The use of the MR-9 Adapter in the Leicameter MR and 
the Leicameter MR-4 can be problematic because the 
central negative electrical contact of the battery 
chamber consists of three ‘fingers’. The tip of one of 
these fingers can slip round the negative contact of 
the adapter and make contact with the positive side of 
the adapter to make a short circuit. It is finely 
balanced and the smallest movement of the adapter/cell 
can trigger a short circuit.
One solution is to insert a small strip of plastic or 
similar spacer between the adaptor and the wall of the 
battery compartment. Insert it just opposite the 
positive metal strip that goes up the side of the 
compartment. The inserted plastic strip fixes the the 
adaptor and prevents any movement.
