Pentax K1000 meter problem

Hi all, I have been using my K1000 for a few months but only encountered this problem recently. When there is a lens on, and I move the aperture ring, the meter works. However, when I change my shutter speed, the meter needle stays the same. Is there any way to fix such a problem? Thanks!

It could need a fresh set of batteries. Failing that, I would suspect it needs servicing.

Until then, remember that the only thing the batteries control is the meter; the shutter can do without. In an emergency, this may get you by.

Exact same issue with my recently purchased Argus-Cosina STL-1000. Bonus: metered values are 2-3 stops under.

I believe the shutter speed dial has a potentiometer that communicates the speed to the metering circuitry. if this is busted or disconnected then you would see what you're seeing. There is a service manual here
Pentax Manuals
which seems to have a good bit of detail in it.

Try sweeping the shutter speed dial from slow to fast 20 times watching needle if it does not twich at all you may need to remove the top plate to investigate.

Cheapest and easiest solution is to get a used [/working] hand-held meter, e.g. sekonic auto-leader, which you should be able to pick up for US$20-30. You will usually get better exposures by metering off the subject, rather than relying on the camera's TTL 'center-weighted averaging' mumbo jumbo (this applies to the old, manual cameras with CDs-cell TTL meters -- modern film slrs and even p+s have very accurate metering IME).

I don't think I said easy to get the top plate off?

If there is no movement of the needle then you may have

a bad solder joint
a damaged resistor track
a damaged resistor track wiper

If you are skilled with a miniature soldering iron reflowing solder joint is easy.
A damaged resistor track you need a replacement part put lid back use hand held meter
The wiper you need dexterity.

If you need an on camera meter buying another body is probably cheaper than repair.
Most of the time I don't have a battery in mine, hand held or sunny side /16.

For E6 incident dome on hand held meter is best option.

I'm with you in checking it out, I was the one that said it should be easy to get into. Reading the instructions, there is a tab connecting the dial to the resistor that reads the shutter speed (and ISO - as a combination of the two, basically two dials in one), it could be something as simple as this being damaged or missing.

For a meter, lately I've been using the Pocket Light Meter app for iphone/ipad and this seems pretty good - if you have that phone then it makes it very convenient, either as a fallback or for checking a camera against.
