Sorry about the lack of information in my original post Matt. This is a
volt meter, and all I want to use it for is to monitor the condition of
my battery when there is no charge being applied to it.
This old meter has a screw where I can adjust the full scale landing
position of the needle/pointer, so I don't think I need anything real
complicated to accomplish what I want to do You mentioned a resistor,
and if that will get me close in the ballpark I can fine tune the meter
with that adjustment screw from there.

That screwdriver adjustment is really a "fine tuning" adjustment to
allow you to set the meter to read zero with no voltage applied - it
will likely have very little effect on the full-scale reading.

A series resistor equal in value to the internal resistance of the
meter should double all readings - that is, the meter would read 6
volts with 12 volts applied to the resistor/meter combination.

  • Re: Puzzling IR remote control problem
    ... The symptom does have some similarities to an electrolytic with ESR issues, if you are going to get into fault finding you really do need to invest in an ESR meter such as the Dick Smith ESR meter, changing caps in a random manner is more likely to result in damage to PCB tracks or solder bridges which would certainly make the fault become permanent. ... I say this because the signal voltage between ground and the track that connected the IR receiver to the 42 pin IC fluctuated erratically between 2 and 4 volts when the unit was plugged in but not powered on. ... The unit is still not responding to the remote, however, and I am off to radio Shack to buy another $4 IR receiver module to see if that revives it again. ...
