I am enjoying my new (to me) Nikkormat EL-W. However, it seems that the camera's light meter never turns off. With the AW-1 winder attached, the meter is supposed to turn off when the shutter release lever lock is switched to the off position. I have noticed that even with the lever switched off, the black needle still goes up and down (depending upon lighting) in the same manner as it would when turned on. Thus, it appears to be metering light at all times. I gather my battery will be dead soon. Have I missed anything here?
