    I found a " for parts, not working" Series 3? meter on ebay for $5.00, something, plus shipping, and I planned to use it to replace the face / movement on my other one.

    Turns out, I got the Series 3 working, at least part way.

    New batteries, and a little WD-40 of the Phonelic pads of the selection dials, and it works.

    I adjusted one of the pots for 125 v. by reading the voltage with another meter that I trust.

    Problem is, with the Ohms setting (touching the probes together), the needle jumps to the left, and pegs out. It should go to the right.

    Any thoughts on what might be wrong?

    It is set on DC, and I've tried it on Pos and Neg. with the same result.

    Thanks,
    Gary

    Simple stuff first. Did you put the battery in backwards?

    Does it do it on all ohms ranges. If I recall, there is a single D cell for low resistance range and 4 AA cells for higher resistance ranges.

    Weird,
    The markings on the board are wrong, for the D-Cell battery.

    When I inserted it in backwards, just now, it's working fine, for both ranges???

    It had been repaired, perhaps he simply put the battery posts back in the wrong way.
    I'll swap them back around so it will be right.

    I knew I put it in right, but I didn't know he had put the posts in backward.

    Thats why he sold it so cheap, he said he couldn't get it working even though he had repaired corroded terminal ends.

    Okay, EDIT, when I took the cover off, and looked real close, I saw a tiny + sign on the right, yet on the board, down below the batterty, it says "METER", and the + sign is on the Left. See photos..

    Perhaps the entire battery holder is in backwards.


    Sweet,

    Thanks,
    Gary

    The plus/minus on the board marked "meter" is for the meter.:confused:

    It all looks right to me.

    Please explain "for the meter"?

    I've never seen that printed on a board, so since it was right below the battery box, I assumed it was referring to how to "install the battery into the meter", but apparently that's not the case.

    I don't feel so bad, since you guys lead me to reverse the battery.

    Apparently the same mistake was made by the previous owner.

    Is the "+ Meter -" a connection point for conducting some type of self test, or secondary test on the unit?

    Please explain further:confused:.

    Thanks,
    Gary

    It's for the Meter connections, the thing you view from the front with the pointer that moves.

    If you had the meter movement by itself you would see it has two studs in the back like this:

    (Ignore the notes on the pic)

    The two studs not only hold the meter in place but provide the place for the voltage to enter the meter.

    Okay,
    It's like a marking on the board for a fuse, or a resistor, etc.
    I get it now.

    Thanks,
    Gary
