temporary jumper between terminals F-F. Connect
the ohmmeter across the cad cell leadwires;
resistance should be less than 1600 ohms.
Stop the burner and remove the temporary jumper.
With the burner off, check the dark cell resistance
across the cad cell leadwires. Resistance should be
greater than 20,000 ohms.
