Hi there, do you have an old drill that's no longer working, that is sitting in a cupboard somewhere. If you do then here is your chance to get it working again.

What can go wrong with a drill?

- The cables in side the plug can come out, this will prevent the drill from powering up.

- The cable can break inside the insulation, this will make the drill malfunction.

- The speed dial on the trigger can malfunction.

- The brushes can wear out.

the first way to check is.

- Plug the drill into the wall point, and pull the trigger, keep holding the trigger while bending the cable and moving it anticlockwise, if the drill works then skip to STEP 3.

Supplies

The things that you'll need are:
- A screw driver, that will unscrew the screws in the drills, and one that'll undo the plug.

- A pair of pliers.

- A pair of long nose pliers.

- A multimeter that has continuity

( if you don't have one check this link,).

Home Made Continuity Tester

Step 1: Checking the Plug.

If the plug is a molded plug skip this step.

(1). Make sure that the plug is out of the wall socket!

(2). Open the plug, it is, normally held closed by a clip, or a screw.

(3). check that all of the wires are screwed in properly.

If they are, then proceed to next step.

Step 2: CHECKING THE SPEED DIAL.

(1). Close the plug, and plug it into the power.

(2). Turn the dial on the drill trigger to the one extreme, and then pull the trigger down.

(3). If this doesn't work turn it to the other extreme, and pull down the trigger.

Step 3: Checking the Cable.

(1). Unscrew the screws in the drill.

(2). Open up the drill, and leave the plug open.

(3). Turn the multimeter on, and set it to continuity.

(4). Follow the cable, and find the end where it goes into the drill.

(5). Place one multimeter probe onto the end of a cable, and place the other probe, onto the same colour cable in the plug(look at photo above).

(6). If the multimeter beeps then that cable is fine.

(7). Repeat, with the other cables.

(8). If all of the cables are fine continue to the next step.

P.S. if you don't have a multimeter check out this link.

Step 4: Checking the Brushes.

The next thing that can go wrong is that the brushes can wear out!

(1). Open the drill.

(2). Find the brushes (look in the photo's above) .

(3). Take the brushes out, this is normally accomplished by bending back two metal flaps.

(4). The brushes should be sitting on a long spring, if there is no more brush left on the end, then you'll have to go to your hardware store and buy a set.

(5). once you've bought a new set, place them in the holder's and assemble the drill again.

P.S. watch the movie that you can download.

(6). The drill may sound rough at first, this is because the brushes are flat on the ends, after some use they will get worn round.
