Aircraft Tool Supply SPCT100A Dual Voltage 120 & 220-Volt Spark Plug Cleaner & Tester
If your life is missing that certain spark, maybe you just need to get out of the house more. If your aircraft's electrical system is not getting fired up, that could be a real problem. The Aircraft Tool Supply SPCT100A spark plug cleaner and tester (120/240V switch controlled) will ensure that this sad state of affairs doesn't happen. It accurately and reliably checks the quality of your used spark plugs so you don' have to guess when it's time to replace them. It cleans with a big blast of abrasive and air to remove all carbon deposits and greatly improve efficiency and lifespan. It includes a recessed observation mirror which is angled to fully show the electrodes, which helps the inspection process during testing. This is a very popular unit that has been upgraded and improved to work with both 120V and 220V power sources, eliminating the need to buy 2 devices. The advanced circuitry of this spark plug cleaner-tester prevents thermal overload due to heavy use. This device meets the ISO 9002 standard and includes a full 1-year warranty. See the warranty tab for more information.
I. Initial Preparation
- Unpack the SPCT100A and inspect it for damage. If you find any problems that would affect the operation of your unit, call Aircraft Tool Supply at 1-800-248-0638 to have it serviced or replaced.
- Install the Safety Cap/Turntable onto the SPCT100A unit with the included bolts and nuts. If you want to use the automatic turntable with massive electrode plugs, install the included extension adapters between the base of the turntable and the top of the unit using the four (4) extra-long bolts.
- Load the cleaner section of the SPCT100A by pouring the contents of the included abrasive (1lb bag) into the cleaning port.
- Make sure the Pressure Regulator is completely OFF by turning it clockwise until it stops, and then connect an air source to the air coupler in the back of the unit.
- Important: Adjust the power selector switch on the side of the unit to the appropriate voltage source (either 115V or 220V) before plugging the unit into the outlet. An incorrect voltage setting may result in damage to your unit.
- Plug the unit into the electrical outlet and turn the power switch at the side of the unit to the ON position.
Warning: The SPCT100A produces up to 24,000 volts when testing spark plugs. Therefore, it is essential for safety reasons that you plug the unit into a properly grounded three-prong outlet. If you do not have a grounded outlet (or are not sure), then clip the auxiliary grounding wire to a ground source such as a water pipe. The auxiliary grounding wire has an alligator clip at the end, and is located next to the power cord.
II. Cleaning the Spark Plug
- First make sure the correct gasket adapter for your size plug is installed in the cleaning port. The SPCT100A comes with rubber gaskets for 12mm, 14mm, and 18mm plugs. Note: aviation massive electrode plugs require the 18mm gasket.
- Insert the spark plug into the cleaning port until it seats itself on the gasket. Youíll find it easier to insert the plug if you apply a slight twist as you push the plug into the gasket.
- If you wish to use the automatic turntable, insert the tail end of the plug into one of the holes of the turntable carousel. If you are using massive electrode plugs, then you must first install the included extender kit to raise the turntable to the correct height. Next, place the included 400AD electrode adapter into the spark plug and attach the tail of the adapter to the carousel.
- Slant the plug by 15 degrees while holding it with your forefinger (for manual mode) and revolve it slowly while pressing the sand-blaster switch. If you are using the turntable carousel, then it will automatically maintain the proper angle as it rotates the plug in the cleaner.
- Check your work every 10 seconds by pressing the clean-air switch to clear away and residual abrasive and then remove the plug for inspection. Repeat as needed until the plug is cleaned to your satisfaction. Do not operate the sand-blaster for more than 10 seconds at a time, as this may lead to over-cleaning and a worn out spark plug tip.
- In certain situations, the abrasive may become stuck to the inside of the sand-blaster tip. This condition is due to very high humidity and can be corrected by cleaning the abrasive off the blaster tip and replace the abrasive in the bag with a fresh batch. The SPCT100A uses a dual-bag arrangement to keep dust down to a minimum, so remember to clean both the inner and outer liners when changing abrasive.
- The included bag of abrasive will be sufficient for about 300 to 500 cleanings.
Note: The SPCT100A does not remove lead deposits from spark plugs. The proper way to remove lead deposits is with either the Aircraft Tool Supply Vibrator Cleaner (p/n PA01), or a good set of Dental Picks (p/n E900-205). Visit us online at www.aircraft-tool.com for more details on either of these products.
II. Testing the Spark Plug
- First, use a spark plug gapping tool to properly gap the plug according to the manufacturerís specifications. When gapping, remember to check your work with a feeler gauge.
- Insert the appropriate thread adapter (12mm 14mm, or 18mm) into each of the two testing port holes located on the top right of the SPCT100A. When testing spark plugs you must always use both holes. The usual arrangement is to have a new spark plug in one hole and the cleaned plug in the other so that you can compare the cleaned plug directly against a new one.
- Carefully connect the high-voltage lead to the plug being tested. When testing massive electrode spark plugs, place the included 400AD adapter into the spark plug and connect the high-voltage lead to the tail of the adapter.
- Slowly turn the air regulator knob in the counterclockwise direction to pressurize the test chamber until the pressure gauge reads between 7 and 10 Kg/cm2 (100 to 140psi). The pressurization is intended to simulate the firing conditions inside an engineís cylinder. You do not have to apply a specific pressure when testing, but you must make sure that itís always inside the "test" range when evaluating a spark plug in order to correctly assess the plugís condition. The test range is the yellow region of the pressure gauge.
- Check the quality of the spark by looking in the reflector mirror while holding down the Spark Tester Switch. Note: Do not depress the switch for more than 10 seconds per cycle, as this may cause the overload protection circuitry of the SPCT100A to engage and temporarily shut the unit down.
Warning: At this point, we must again caution you that the test section develops up to 24,000 volt, so do not touch the spark plug or the high-voltage lead while depressing the Spark Tester Switch!
- Perform the same test for the other plug to get a comparative reading of the cleaned plug against the new one. When a plug is in good condition, you should see a nice blue or blue-green spark at pressures of 6 Kg/cm2 or higher. Bad or marginal plugs will show a reddish spark, or no spark at all under pressure. Also, as a rule of thumb, the pressure at which the cleaned plug fires should be within 2.5 Kg/cm2 (35psi) of the new plug. If it isnít, then consider replacing the spark plug.
- In some cases, the ambient light of the room may be too high to clearly see the sparks, so be sure to do your testing in a room with a relatively low lighting level.
