SECTION 4 – MAKING A DISCHARGE TOOL IF YOU DON’T HAVE ONE

Even when the unit is disconnected from mains power, the risk of shock or shorting from the PSU unit is high.

The mains capacitor can hold considerable voltage. You should as a matter of precaution discharge the mains

circuit BEFORE you repair the PSU. Do this using a suitable discharging tool or make your own as detailed

here.

Making a Capacitor Discharge Tool - You can make a capacitor discharge tool fairly easily. You will need…

2 x INSULATED alligator clips

40cm of 14awg stranded wire

10k ohm, wire-wound, 10 WATT RESISTOR

Solder an alligator clip to both ends of the 40cm wire. Then cut the wire about 18cm along from one end, and

layers of ELECTRICAL TAPE. Alternatively, you can use heat shrink tube, at least 2 layers of it, one over the

other. PICTURE 2 below is what it should look like when finished, or similar anyway!

(DO NOT TRY TO DISCHARGE YET - SEE BELOW IN THE “REPAIRING YOUR PSU UNIT”

SECTION FOR WHEN TO DO THIS)
