IMPORTANT! –It is the user’s responsibility to verify proper ignition timing and ensure
proper timing lever position before attempting to hand crank Model T engine. Failure to
verify proper ignition timing may result in serious personal injury. Ignition coils produce
high voltages capable of causing personal injury or death. Do NOT touch coil electrical
contacts or points when coil testing is in progress. User assumes all risks and liabilities.
IMPORTANT! : Make sure there is no source of combustible fluid or gas anywhere near
the ECCT or coil under test that could be ignited by electrical spark. Shock Hazard: Do
NOT touch coil unit electrical contacts, coil points or coil Test Fixture Spark gap when coil
test or multi-spark testing is in progress. Do NOT operate the ECCT with clear protective
safety shield covering the spark gap removed. User assumes all risks and liabilities.
1ECCT Description
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. The
ECCT permits point adjustment by coil dwell time to fire so that each coil can be precisely
adjusted to minimize coil to coil (cylinder to cylinder) ignition timing variation for optimal
engine performance.
1.2 Capacitor (Condenser) Tester
The ECCT can test the Model T coil internal capacitor (condenser) for proper value as well as
leakage to ensure proper spark and maximum point life.
1.3 Magneto Tester
The optional magneto test function enables the ECCT to test the strength of the Model T
magneto output to ensure proper coil operation.
1.4 Advanced Features Software
Numerical and graphical display of ECCT coil, capacitor and magneto test data is can be
provided with the optional Advanced Features Software. Additional test capability is also
provided including:
1. Display the coil inductance, coil firing current, spark energy and coil dwell time to fire
2. Ability to change the number of coil firings in Multi-Spark mode (2 to 250 firings)
3. Ability to change the coil firing rate in the Multi-Spark mode (375 to 5000 RPM)
4. Display engine RPM, Magneto RMS voltage and Magneto internal resistance in Magneto
Test mode.

2Test Modes and Results Display
This section describes the ECCT test modes and how to read test results on the ECCT display.
Figure 1 - ECCT Display and Buttons
2.1 ECCT Button and Display Description
2.1.1 Power Input
Supplies 12VDC power to the ECCT
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. Press and hold the select button for 5 seconds to turn the ECCT power Off. Note:
Magneto Test Mode cannot be selected unless that optional test mode has been licensed.
2.1.3 Function Display
The selected test function is indicated by illuminated Red LED

2.1.4 Test Button
The Test button is used to start the selected test. Press and release the test button to run the
selected test.
2.1.5 Test Result
Test results are categorized as Poor, Good and Excellent and indicated by illuminated LED
display.
2.1.6 Timing Error Display
The LED display is used to indicate the coil dwell time to fire. That is; how long it takes the coil
to fire spark measured from the time the test button is released. The dwell time to fire is
displayed in crank shaft degrees assuming the engine is turning at 1,000 RPM. Coil points
should be adjusted for 0 Timing Error (Center LED) which is considered ideal and indicated by
the Excellent LED being lit. Coil points that fire within +/-1 degree of 0deg is considered
acceptable and indicated by the Good LED being lit.
2.1.7 Capacitance Display
This display is used to indicate the value of the capacitor (Condenser) internally connected
across the point terminals. The scale is calibrated in microfarads (uF) with standard values
indicated. The proper value of capacitor connected across the coil points is 0.47uF.
2.1.8 Magneto Test Result Display (optional feature)
The strength of the magneto output is indicated by on the LED display upon completion of the
magneto test. The regions marked 1914 and 1915 correspond to the magneto field strength
measured by the St. Louis Magneto Tester. The magneto output is considered good if the
reading reaches or exceeds the 1914 range. Few if any magnetos of later model years were
capable of higher output. The 1915 range was included for consistency with the well known St.
Louis Magneto Tester.
2.1.9 Magneto Test Input
Input port for magneto test leads. One lead is connected to the magneto output post, the other
lead is connected to engine ground (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.
