    HI, I have an old Craftsman clamp on analog multimeter that I want to resurrect. I can't find any data sheet or information about this 82024 Craftsman meter anywhere on the internet. Some components on the board are missing and I want to know what goes there. If anyone has information about this meter please tell me. There are AC, DC, AC amp and Ω meters on this multimeter. How can I make these circuits for analog meter? How should I approach my problem?

    P.S. This multimeter looks super cool and I want to make it work.

    Show the rear of the circuit board.

    It looks as if that meter has seen some serious overloading in its life. Check that the meter (dial) itself still works as without it the meter is useless and the indications of an overload/blown meter are all there. Use a 1.5V battery and series resistor (say 1k) to make a temporary connection to the meter terminals - the pink and purple wires - to see if there's any deflection.

    I tested my galvanometer and the needle went all the way to the right so I assume it is still working. What should I do next?

    Looks to me like only half of the meter is there.
    Selector plate, springs balls all missing.
    Looks like the board coped some overheating as well.
    Not really worth even thinking about.
    Especially when an el-cheapo one can be had for maybe $30 on Ebay.

    The circuits seem fairly simple I just need to know what components are in it. Do you have some simple analog multimeter circuits?
