TOOLS AND EQUIPMENT
Introduction Components will usually be removed, inspected and repaired or replaced when a defect has been diagnosed. Other components are replaced, or stripped and cleaned, at scheduled mileage or time intervals. Refer to the Routine Maintenance section for details on these items.
General Toolkit General tools and equipment will be required for most tasks. As your career develops you will build a collection of tools and equipment. Look after your tools and they will look after you!
Electrical Tools There are only a few tools specifically associated with electrical systems. Some of the main

screens. Terminal Kit Many terminal kits are available. They usually
consist of a selection of terminals and special pliers to crimp the terminals on to the wire.
Wire Strippers With practice you will be able to strip wire using side cutters. However, special tools are available to make the job easier. A number of different types are shown here.
Soldering Iron Most soldering irons are electrically heated. However, there are some very good gas powered types now available. The secret with a soldering iron is to use the right size for a specific job. One suitable for delicate ICs and circuit boards will not work on large alternator diodes. More damaging would be to use a large iron on a small circuit board!
Paper Clip Not found in Snap-on or other catalogues, but a very useful tool. It is not only ideal for bridging terminals as shown here; it can

Summary Small tools such as electricians’ screwdrivers or wire cutters are easy to misplace when working on a vehicle. The cost of these items if you lose them is clearly an issue, but so
is the chance of damage to the vehicle. A ‘spanner’ in the works – can cause lots of trouble!

ROUTINE MAINTENANCE
Scheduled Servicing Scheduled service requirements are often quite simple but none-the-less important. Systems should be checked for correct operation. Adjustments, repairs or replacements are then made if required. The servicing requirements for body electrical components are therefore still significant.
Non-Routine Work When carrying out routine maintenance, some non-routine work may be found. This should be reported to the driver or owner of Damaged
