gnition Coil Testing
Figure 6-26 Testing Pickup Coil
1. Connect ohmmeter between "B+" or "C-" termi-nals
and ground (coil bracket). On high scale, reading
should be infinite (test 1, figure 6-26).
2. Connect ohmmeter between "B+" and "C-"
terminals. On low scale, reading should be nearly
zero (approximately 0.4 ohm) (test 2, figure 6-26).
3. Connect ohmmeter between "B+" or "C-" termi-nals
and coil high-voltage tower. On high scale, reading
should be approximately 8000 ohms. Reading
should not be infinite (test 3, figure 6-26).
NOTICE
On tests 2 and 3, reading may vary slightly depending
on coil temperature.
4. If reading is not within specifications, replace coil.
EST Distributor Removal
1. Remove distributor cap (2 screws). Do not remove
plug wires from cap unless necessary.
2. Disconnect distributor primary leads at coil.
3. Crank or turn engine slowly. Align timing marks
when rotor is pointing to No. 1 terminal of distributor
cap. If same distributor is to be reinstalled in engine,
mark position of distributor housing in relation to
engine so that distributor may be installed in same
position.
4. Remove distributor retaining clamp.
5. Remove distributor.
NOTICE
To simplify distributor installation, do not turn
crankshaft with distributor removed from engine.
