I got the body and lenses from KEH today. Put a Wein 1.35v 625 battery in it. It checked out good with the battery check. The meter works, but does not move when indoors. It won't move until you aim it toward the light bulbs. Is it normal for the meter to need more light than what you get indoors?

Hello,
check your camera against a reliable light meter or another camera. Normally a camera like the SRT or a Spotmatic can measure indoors. But the CdS cells can loss sensitivity with the years so the measured value can be off 1 to 2 f-stops or maybe the meter shows no movement. You can compensate this sometimes by setting a higher speed value. In dark light the CdS cells are sometimes very slow and you have to wait some seconds for a stable result.

When new the meter's working range was from EV3 to 17 when set to ASA100.

You should be getting some movement but the most likely problem is yellowed glue bonding the meter cell blocks to the prism which is a common problem with srT meters. The yellowed glue will block light from getting to the cells and cleaning and re-glueing will bring the meter back to life..

It is hard to know what you mean by "indoors". Indoors facing a sunny spot illuminated by a south facing window in the middle of the day is a heck of a lot different from indoors illuminated with artificial lighting. In my experience artificial light will not move a meter unless you aim right at it, and for a typical lamp (40 -60 watt) you need to be pretty close.

Either compare it to a known meter as suggested above, or take it outside when the sun is shining and you know that the exposure should read.

I was in a small bedroom lit with 4 CFL bulbs that are 75 watt incandescent equivilant.
