Repair of a Vintage Simpson 461-2 DMM
Excavatoree:
Thanks. I've got one of those, and I may need to do that.
By the way, does yours take some strange battery? I can't figure out what mine is suppose to use. (So I use alligator clips and a power supply)

Good repair and restoration. Thanks for the tip on these switches. I will have to remember this thread for the future.

It came with two NiCad packs, each of which which consisted of two smaller NiCads shrink-wrapped together. Of course they were no good. It will run off of 4 AA batteries but it's not made to hold them as such, unless you shrink-wrapped two together to make on long battery like the original had. I don't plan on ever doing that, just run it off the charger jack, it works just fine that way (assuming it's fixed like mine isn't yet :))

Thanks. I'm just going to pull out all the switch insides now, and clean them. Hopefully the LEDs will show up early this coming week.

And now a plastic piece that holds a brass insert for the rear screw popped off. Glued back on with model cement. :palm:

The vintage LEDs arrived today. Meter is looking good! I think we're on the downhill side of this project now. :clap:
