Fireball battery
 
Where on the MPU of a Fireball Classic does a remote battery holder connect?

On the bottom center of the mpu board you will see the two battery solder connections. The negative connection should be on the left, itís connection will be connected to the trace that runs along the outside edge of the board. The positive connection should be to the right of the negative and marked with a +.

I found the + terminal and what looks like the negative terminal which does connect to the outside edge trace (ground). my board may be a different vintage as the - terminal is on the right of the + terminal. could that be the case?

what voltage range should be required? I read approximately 3.6 VDC on a schematic somewhere.

Thank you

Guess I had it backwards. As long as you see the + sign for the positive. And you are correct about the voltage.
