Battery Replacement

For meter repair, See Here

There are two basic models of meter, internal and external ta counters. They use the same battery, however, one of the low voltage leads is blue, and one is white. In order to replace the batteries, first cut the wires with a pair of wire cutters. Notice the corrosion on the battery on the right. It is junk now.

There are two different styles of boards as well. The first picture is of the board from the earlier External Ta counter models.

The other board is in the later models with the internal TA counter.
