    Hello all,

    I'm just new to newsgroups, so here goes.

    I recently bought an Electro 35 GT on ebay. It looks in good order,
    fitted a 6 volt battery with spring and it seems to work OK.
    The only thing is the indictor lights in the viewfinder are a bit
    erratic.
    They don't work at all until the shutter has been wound on, but I'm
    guessing that this is normal. After winding the shutter I have to work
    the shutter release up and down few times to get the indicators to
    light up. I think they worked better than this when I first put the
    battery in, about two weeks ago.
    The battery check lamp works fine, so I'm wondering if there may be
    some dirty contacts for the exposure indicators. Any ideas from
    anyone?
    I've repaired a few cameras so I'm prepared to have a go myself if
    someone can tell me what might be wrong.

    Many thanks

    Richard

    I have a couple GT cameras, and they both work that way. One is more
    touchy than the other in regards to shutter button position to activate
    the light meter.
    The materials used for the contacts, many of them gold plated, are very
    corrosion resistant. It is unlikely that corrosion is a problem. The
    shutter button assembly is about the height of the camera, and activates
    many other parts. There are some small contacts that need to line up, and
    have certain distance gaps. Over time, those gaps can widen, and misalign,
    causing a poor connection.
    I do not have an exact idea of what contacts you can move to make your GT
    work better. However, there are some images that might help:

    This camera is very similar, and should help you get into the guts of your
    GT. One thing to watch out for is the flash sync connection, since that
    usually snaps off when you remove the top cover. If you are good with
    solder, it is easy enough to repair.

    I have taken both my Yashica GT cameras apart, cleaned and adjusted them,
    adjusted the rangefinders, and modified the finder housing to greatly
    improve the contrast. These are great cameras for low light and available
    light photography, or just great cameras to take into harsh environments.
    Best of luck with your GT.

  4. i've also had this problem..from what I understand its an issue inherent in
    the camera. when it works, it works well, but thats only half the time.
    hope you didnt pay too much for it...
