ELECTRICAL HAND TOOLS




Test Lights  Are used to test for electricity. A typical test light consists of a clear plastic screwdriver-like handle that contains
a light bulb.


A wire is attached to a terminal of the bulb, which is connected
to a clean metal part of the vehicle. The other end attaches
to a point that can be used to test for electricity at a connector or wire.

When there is power and a good connection, the light bulb lights.
A typical 12-volt test light.
Soldering Guns
*
Electric soldering gun  This type of soldering gun is usually powered by 110-volt AC and often has two power settings expressed in watts.
An electric soldering gun used to make electrical repairs. Soldering guns are sold by the wattage rating. The higher the wattage, the greater amount of heat treated. Most solder guns used for automotive electrical work usually fall within the 60- to 160-watt range.
*
Electric soldering pencil  This type is less expensive and creates less heat than an electric soldering gun. A typical electric soldering pencil (iron) creates 30 to 60 watts of heat, suitable for soldering smaller wires and connections.
*
Butane-powered soldering iron  Is portable and very useful for automotive service work because an electrical cord is not needed. Butane powered irons produce about 60 watts of heat.
Most service techs who do electrical-related work should have:
*
  • Wire cutters 


  • *
  • Wire crimpers 
  • *
  • Wire strippers 
  • *
  • Heat gun 
A digital multimeter, abbreviated DMM, is necessary for electrical diagnosis and trouble shooting. It is usually capable of measuring the following units of electricity:
*
  • DC Volts 
  • *
  • AC Volts 
  • Ohms
  • Amperes
