Thanks for the input, I do have a donor camera with a working meter, but obviously I don't know exactly how to repair this thing! By the way, how do I take the cover off? I'm stuck at the advance lever.

As you get into it you can generate lots of questions. For the Spotmatic a great resource is the National Camera soptmatic repair manual. It was part of their technician training course, and covers full teardown and assembly.

I know this is an old thread, but before resorting to opening up your camera, try this.
I bought a SPII with a 55mm f1.8 SMC Takumar lens pretty cheaply off ebay recently. Everything was fine apart from the light meter, which was stuck in the centre after replacing the spent battery with a new AG3. I opened the lens up to f1.8, activated the meter and shone one of those bright white LCD torches into it for a second.
Seconds later it was working & after testing it against the meter on my K1000 its giving accurate readings.
Hopefully this will work for others with the same problem.

@K1000x, I registered to thank you for this hint -- it seemed silly but the light meter in my otherwise excellent-looking Spotmatic was alternating between complete over- and under-exposure like others reported above.

I did what you suggested -- turned on the torch in my phone, activated the light meter, pointed the camera at the light for a few seconds from close distance and bam! the meter suddenly works just fine!

Had to flip the battery upside down too to fix the indicated value but that's all (by the way, I'm using a Varta V394).

Many thanks again!

I had the same problem with my 4 spotmatics and I solved, how? See below

Turned the battery upside down, flat surface down to contact the bottom of the hole, and bingo. Everything works fine.

I'm glad you revived this discussion, Pepe. I've bookmarked it. Useful for all the diffferent battery numbers that work on the Spotmatic, as well as the tip on the contacts under the base plate.

My SP's meter works intermittently. So I removed the bottom plate and examined the contact on the base of the camera. It showed some evidence of corrosion, so using the smooth side of a pretty well worn out emery board (I actually broke a small piece off the end), I was able to smooth out that contact, make it shiny again.

The meter is still intermittent. Curiously, when the meter is activated, often it shows a a reading lower than it does when it's off. Fiddling with the shutter speed dial -- and sometimes even the film advance lever can cause it to unstick and peg itself at the top -- if I have a slow speed dialed in. After that, it usually responds to aperture and shutter speed settings. I'd like to figure out what's causing this. It's annoying. But then it's probably close to being a 50 year old camera, so maybe I should cut it some slack.

These posts are very useful when we google for a problem solution

Michael, I discovered through Google that the Spotmatic F uses the battery with the + sign showing when you put the lid down. The other Spotmatics use the battery flipping it, that is, the + does not show before you put the cover. The flashing light also worked, I did it, it seems like the battery goes to sleep until a strong light wakes it up. Also, cleaning the contact with lighter fluid also helps.

I have a Spotmatic F as well. I vaguely recall that it's battery is reversed from the other Spotmatics. It is sitting inside my photo gear cabinet right now, so I don't have a battery loaded in it. I guess I should drag it out, load a battery to wake up its meter, and cycle the shutter a few dozen times, just for good measure.

Thanks for the tips in this old thread! I have a Spotmatic Sp II which came in a lot with four lenses. I wanted the lenses, but left the camera untouched for long. Now I've just revived it and the light meter came back to life thanks to the advice given here. Just the one addition: I popped out the blastic bottom of the battery holder, (unscrewing the bottom plate) so as to make space for the thicker LR44 battery. A tip on Youtube.

I would have suggested getting a 387S battery rather than modifying the holder. At least that is what I use on my Spotmatic and Spotmatic II. As for battery choice, I would suggest a SR44 due to longer life and better voltage profile on discharge than the LR44.
