DESCRIPTION
All EEC-IV controlled engines use the TFI-IV ignition system.
The TFI-IV distributor is a gear driven, die cast unit. On models with
3.8L engines, a "closed bowl" distributor is used. The TFI ignition
module is mounted on the cowl behind the engine (Continental, Sable &
Taurus) or the radiator crossmember (Cougar/Thunderbird). On all
others, the TFI ignition module is integrally mounted in the
distributor. A Hall Effect stator assembly replaces the coil stator.
This distributor does not use conventional centrifugal/vacuum advance
mechanisms. See Fig. 1.
The TFI ignition module is contained in molded thermoplastic
and is mounted on base of distributor. See Fig. 2. The TFI ignition
module used on manual transaxle equipped vehicles features a push
start mode. This feature allows vehicle to be push started if
necessary. An "E" core ignition coil is used.
OPERATION
The TFI-IV distributor uses a Hall Effect switch mechanism to
switch primary voltage and to trigger the discharge of high secondary
voltage. Crankshaft position and engine load signal is supplied to the
EEC-IV Electronic Control Assembly (ECA) to compute spark advance.
Distribution of high secondary voltage is accomplished through a
conventional cap, rotor, and spark plug wires.

TROUBLE SHOOTING
NOTE:
See the TROUBLE SHOOTING - BASIC PROCEDURES article
in the GENERAL TROUBLE SHOOTING section.
TESTING
PRELIMINARY STEPS
1) Visually inspect engine compartment to ensure that all
vacuum hoses and spark plug wires are properly routed and securely
connected. Examine all wiring harnesses and connectors for insulation
damage, burnt or overheated wires, and loose or broken terminals.
2) Ensure that battery is fully charged and that all
accessories are off. Check that TFI ignition module is securely
fastened to distributor base. Obtain Spark Tester (D81P-6666-A). A
spark plug with a broken side electrode is NOT recommended as it may
lead to incorrect results.
3) When inspecting wiring harness, both a visual inspection
and a continuity check should be performed. When checking continuity
perform a "WIGGLE" test to assist in finding intermittent faults.
IGNITION COIL SECONDARY VOLTAGE CHECK
1) Connect Spark Tester (D81P-6666-A) between ignition coil
wire and engine ground. Crank engine while checking for spark at
tester. If spark occurs, inspect distributor cap and rotor for damage
or carbon tracking. Make sure rotor tip is coated with Silicone
Dielectric Compound (D7AZ-19A331-A).
NOTE:
Do not use dielectric compound on multi-point rotor.
2) If no spark occurs, measure resistance of ignition coil
wire. If reading is greater than 7000 ohms per foot, replace ignition
coil wire. Inspect ignition coil for damage or carbon tracking. Crank
engine while checking distributor rotation. If these items are okay,
go to IGNITION COIL PRIMARY CIRCUIT SWITCHING test.
IGNITION COIL PRIMARY CIRCUIT SWITCHING
Except 3.8L
1) Disconnect wiring harness connector from ignition module.
Inspect connector for dirt, corrosion, or damage. Repair if necessary.
If okay, reconnect harness. Connect a non-powered, 12-volt test light
between coil "TACH" terminal and known good engine ground. See Fig. 3.
2) Crank engine while observing test light. If test light
comes on or flashes, remove test light. Proceed to IGNITION COIL
PRIMARY RESISTANCE test.
3) If test light does not light or if it is very dim, remove
test light. Proceed to PRIMARY CONTINUITY TEST.

IGNITION COIL PRIMARY RESISTANCE
1) Place ignition switch in "OFF" position. Disconnect
ignition coil connector. Inspect connector for dirt, corrosion, or
damage. Repair if necessary. Measure resistance across ignition coil
positive and negative terminals. See Fig. 4.
2) If reading is between 0.3-1.0 ohms, ignition coil primary
circuit is okay. Go to IGNITION COIL SECONDARY RESISTANCE test. If
resistance is less than 0.3 ohms or greater than one ohm, replace
ignition coil.
IGNITION COIL SECONDARY RESISTANCE
1) Place ignition switch in "OFF" position. Disconnect
ignition coil connector and secondary wire from coil tower. Measure
resistance between negative coil terminal and coil tower. See Fig. 4.
2) If reading is between 6500-11,500 ohms, ignition coil is
okay. Go to WIRING HARNESS test. If reading is less than 6500 ohms or
greater than 11,500 ohms, replace ignition coil.

2) Attach negative voltmeter lead to distributor base.
Measure voltage at battery. With negative lead of voltmeter still
connected to distributor base, check voltages at TFI ignition module
wiring harness terminals. See WIRING HARNESS CHECK table. See Fig. 5.
3) If all readings are at least 90% of battery voltage,
wiring harness is okay. Turn ignition off. Remove voltmeter. Connect
"S" terminal to starter solenoid. Proceed to appropriate STATOR test.
4) If any reading is less than 90% of battery voltage,
inspect wiring harness and connectors. Also check for a worn or
damaged ignition switch. Repair or replace as necessary. Turn ignition
off. Remove voltmeter. Connect "S" terminal to starter solenoid.
