Both of my 18v and 12V chargers stopped charging. The 18V one is for a B & D trimmer and the 12v one is for a B & D drill. They charged last time but the next time they did not work. Neither of the Red and Green lights no longer light up. This indicates that the chargers are faulty.
I then tested the output voltage of the charger's transformer with a multimeter: http://www.altronics.com.au/p/q1053a-digital-multimeter-19-range-with-transistor-test/
The charger's mains-transformer output was 0V on both chargers. Then I used my bench power supply (http://www.altronics.com.au/p/m8303-powertran-30v-3a-regulated-bench-top-power-supply/ ) to supply voltage to input side of the charger's circuit board (24V DC to the 18V charger; 15V DC to the 12V charger). I did this by soldering temporary wires (from the DC power supply) to the output of the rectifier diodes. The charger(s) immediately came to life. (they successfully charged batteries). Therefore, replacing the transformer should fix the charger. You can find the replacement transformer for both chargers here: http://www.jaycar.com.au/Power-Products-Electrical/Power-Conversion-%26-Transformation/AC-AC-Transformers/15-30V,-30VA,-1A-Multi-Tapped/p/MM2008
