I have this circuit. It is powered by 9v battery. With sw1 open, it is on low scale. With sw1 closed, it is on high scale.

**broken link removed**

But I would like to get rid of sw1 and add a second lm3915 with 10 LEDs. My thought were to do this.

**broken link removed**

But it does not work.
Any help would be much appreciated.

The IC5B circuit is just a low battery indicator that uses reference voltage from pins 6&7 of IC4.
The original circuit works fine. i would just like to have a full scale LED display instead of a scale switch.

Thanks to all.
