Electrical Projects The electric home manicure kit is only one of several types that are on the market today. The unit consists of a power-pack assembly in the case which incorporates a transformer to step down the house line current to a safe level and a diode to rectify the ac (change the ac to dc). The 15V dc output of the power pack is fed through the terminal board to the cord set and into the power handle assembly. A small dc motor in the power handle assembly is used to power the numerous manicuring attachments.


Troubleshooting

Two systems are involved: the motor and the power handle.


Motor will not run. Check to see that the switch on the manicure set is placed in the on position. Check the plug on the retractable cord to confirm that it is fully seated on the connector pins, and that the "key" on the plug mates with the slot in the case. If these items check okay localize the trouble as follows:

1.  Connect line cord to 120V ac outlet and pull out the retractable cord plug.

2. With a VOM on the 50V dc range, read the voltage at the connector pins. If the switch, cord, and power supply are okay, the voltage should read approximately 15V.
