- Page 3 1.1 Coil Tester and Alignment Tool The Electronically Cranked Coil Tester (ECCT) is used to test and align Ford and K-W Model T coil units used on 1913 to 1927 model years. It is a unique electronic instrument capable of aligning coil points with ease and precision previously unachievable with previous tools.
- Page 4 2.1.2 Select Button (Power) The Select button is used to turn ECCT power on/off and to select which test to run. Press and hold this button for 5 seconds to turn the ECCT On. Press this button momentary to select test function.
- Page 5 (NOT chassis ground!). 2.1.10 USB Connector The ECCT can be connected to a PC or laptop via standard USB-mini A/B to USB-A data connector. Optional Advanced Features Software is available that provides additional test capability as well as numerical and graphical display of the ECCT test data.
- Page 6 Inspect coil unit points for proper mechanical alignment prior to electrical testing with the ECCT. Figure 2 illustrates proper point geometry with the Vibrator Spring pushed down to rest against the coil iron core with a pencil. Cushion Spring, A, should extend down below the Bridge Element by 0.005”.

3. Turn on ECCT power by pressing and holding the SELECT (Power) button for 5 seconds. The Capacitor test function LED should illuminate. Note: The POOR LED will light when the ECCT is powered up if the coil is not making good contact or there is no coil unit installed. - Page 8 Poor Table 1. Capacitor Test Results Flashing Poor LED – Indicates the coil is not making contact with the ECCT fixture. The Poor LED will be illuminated if the capacitor value is correct but has high leakage. IMPORTANT! - The most important Capacitor Test Parameter is the Capacitor Value.
- Page 9 Press the SELECT button to change to ECCT to Coil/Dwell test function. Press and release the TEST button to run the coil test. The ECCT will measure the coil dwell time to fire with respect to the nominal time in crank shaft degrees with respect to the nominal time and display the result in crank shaft degrees at 1000 RPM.
- Page 10 Nominal coil dwell time is 0.002 seconds (2ms) operating on 12VDC. This dwell time is translated to ignition Timing Error and displayed on the ECCT lower scale calibrated in crank shaft degrees with center value set to the nominal dwell time labeled as 0 degree Timing Error.
- Page 11 Small taps on the Vibrator Spring support make Large changes in coil Timing Error so make small taps and re-test the Timing Error to see how your adjustments affected performance. Refer to the next section if you accidently over adjusted the Vibrator Spring to apply too much tension. V12 ©2019 Mictel LLC e-mail: mictel@comcast.net...

- Page 13 The ECCT checks for Double Sparking during the Coil and illuminates two (2) LEDs on the Timing Error display if Double Sparking is detected as illustrated in Figure 10.
- Page 14 Coils that have passed the Capacitor and Coil tests with Good or Excellent results should then be tested for Coil firing consistency with the ECCT Multi-Spark test. This test fires the coil 100 times at the rate of 2,000 RPM while monitoring the Dwell Time to Fire for each spark.
- Page 15 Model T Electronically Cranked Coil Tester 4.5.3 Multi-Spark Test Results The ECCT illuminates a Timing Error LEDs if 5% or more of the firings occur in that timing bin. A summary of the Multi-Spark coil test results is provided in Table 3 below.
- Page 16 7. Raise the engine idle within 10 sec until the Red Magneto Test LED begins flashing on the ECCT then wait (~ 5 sec) for the test to complete. NOTE: The idle only needs to be raised by about 500 RPM, No need to race the engine! The POOR LED will flash if no magneto output is detected or does not increase with RPM after 5 seconds.
- Page 17 Model T Electronically Cranked Coil Tester 4.6.3 Magneto Test Result Display The ECCT Magneto test result display functions differently than previous tests. Two LEDs may be lit indicating the reading is in between values. Examples of Magneto test results are provided below for reference: Figure 16 –...
- Page 18 No Output - No Magneto output results in no strength LEDs illuminated and a flashing Poor LED. Check the connections between the ECCT, Magneto post and Engine Ground. Make sure the Alligator clips are firmly attached and making good electrical connection especially the engine ground connection.
- Page 19 Detailed coil data and fine tuning is possible with the software. The ECCT connects to a PC or Laptop computer running Windows using a standard USB cable. The ECCT Software communicates with the ECCT providing full control of all tests and displays the following information.

- Page 22 ECCT and could result the capaictor leakage test to fail. Capacitors that test Poor but with Capacitor Value in the range of 0.47uF to 0.56uF do NOT need to be replaced.
- Page 23 7. Press the Green TEST button to test the coil. The coil will fire a single spark and the coil test results will appear in the Blue Coil Test Results window. A summary of the test results will also appear in the Information/Status window. V12 ©2019 Mictel LLC e-mail: mictel@comcast.net www.modeltecct.com...
- Page 24 (0.002 seconds) operating at 12V DC which is approximately 1000 RPM. The time scale is calibrated in crank shaft degrees relative to 0 timing error at 1000RPM. Properly adjusted coils should fire consistently 0 +/- 1 degree at 1000 RPM at least 95% of the firings. V12 ©2019 Mictel LLC e-mail: mictel@comcast.net www.modeltecct.com...
- Page 25 Tapping down on the rear of the Vibrator Spring increases Vibrator Spring Tension. This increases the coil dwell time to fire and moves the timing error to the right. V12 ©2019 Mictel LLC e-mail: mictel@comcast.net...
- Page 26 Reduce Vibrator Spring tension by prying up on the rear of the Vibrator Spring. Prying up on the rear of the Vibrator Spring decreases Vibrator Spring Tension. This decreases the coil dwell time to fire and moves the timing error to the left. V12 ©2019 Mictel LLC e-mail: mictel@comcast.net...
- Page 27 Coils with Insufficient Cushion Spring Tension produce two or more weak sparks that result in poor spark energy, poor combustion and consequently poor engine performance. The ECCT carefully monitors for double sparking and alerts the user if the condition is detected with the Double Spark! warning message above the Coil Test Results box.
- Page 28 8. Test Coil firing consistency by selecting MULTI-SPARK COIL TEST, then click TEST The ECCT fires 100 sparks at the rate of 2000 RPM while measuring and recording the coil dwell time of every spark. The results are displayed graphically to show the distribution of firings expressed as timing error in crank shaft degrees at 1000RPM.

- Page 30 The engine RPM only need be raised just above the tachometer yellow line until the test starts and the status message changes to “Testing Magneto – Please Wait” in yellow. V12 ©2019 Mictel LLC e-mail: mictel@comcast.net...
- Page 31 Magnetic Field Strength Factor of GOOD is sufficient to properly operate Model T coils. IMORTANT: Only use the supplied magneto test cable when testing the magneto. Using longer cable lengths or different gauge wire may cause inaccurate magneto internal resistance measurements. V12 ©2019 Mictel LLC e-mail: mictel@comcast.net www.modeltecct.com...
- Page 32 Model T coil operation. Knowing the magneto internal resistance can be a useful troubleshooting tool since it includes the magneto post contact resistance. The ECCT provides an alert when the magneto internal resistance is above the normal range (>2 Ohms) signaling it is appropriate to remove and inspect the magneto post for proper contact with the magneto coil.

Page 33: Portable Operation
The rechargeable battery is affixed to the rear of the ECCT housing using hook/loop fastener that permits easy installation for portable operation and easy removal for bench operation. The battery plug is inserted into the ECCT 12VDC power jack in place of the AC adapter plug. -
Page 34: Maintenance
Make sure there is no source of combustible fluid or gas anywhere near the ECCT that can be ignited by electrical spark during operation of the ECCT. User assumes all risks and liabilities.
