Do any of you out there know if the Canon 28 has a varible resistor under the top to calibrate the meter? I put some 400 film in mine and I noticed that the needle went clear up into the red zone, above F16, which locks the shutter button. The scene was quite bright and the meter may be OK, but I didn't have opportunity to check it out with my hand held meter. The top shutter speed on the 28 is 1/650, and the top F stop is F16, so it is possible that the scene was just to bright for the meter. Anyway, I was just curious as to whether there is a varible resistor under the top.

Your meter behavior seems quite weird... Are you sure the battery is OK?
I'm pretty sure it's the same arrangement in the 28 but I only have schematics for the 17, on which you have a resistor (15k partlist X64-0902) stuck to the metering module. It's quite easy to find as it's one end of the only red wire...

Anything other than a mercury cell will send the needle off scale. It can be re-calibrated for silver but it's a fiddly business.
I found it took a 22K in parallel and a 300R in series to get it measuring correctly. Finding small resistors is one problem but chip resistors would be fine if you can locate them. Good luck
