Checking the breaker module input on ACCORD 1990-91
1. Remove the distributor cap, rotor and screen.
2. Tag and disconnect 4 wires from the breaker module.
3. Turn on the ignition (to the ON position). Check with a voltmeter for voltage between the black/yellow wire and ground. There must be tension. If there is no voltage, then you need to check the integrity of the black / yellow wire between the interrupter module and the ignition switch.
4. Check the voltage between the white/blue wire and ground; The voltage should be with the ignition on. If not, then check the white/blue wire from the breaker module to the coil. You need to check the ignition coil itself.
5. Turn off the ignition (OFF position). Check the continuity of the yellow/green wire between the module and the ECU.
6. Check the blue wire for continuity between the tachometer and the chopper module.
7. If all tests pass normally, then you need to replace the module.
Checking the input of the breaker module for carburetor PRELUDE 1990 with TOYO DENSO distributor
1. Remove the distributor cap, rotor and screen. Remove the bolts holding the distributor and remove the distributor itself for access. Leave the wiring harness connected to the distributor.
2. Remove the breaker module.
3. Turn on the ignition and check the voltage between the blue wire terminal (1) (outermost blue wire) and weight; tension should be.
4. Check voltage between black/yellow terminal and ground (earth); tension should be.
5. If there is no voltage in any of the tests, turn off the ignition. Check blue wire (1) between the interrupter module and the ignition coil; check black/yellow wire between breaker module, ignition key and coil. Also check the coil.
6. If all tests went well and the problem still exists, the breaker module needs to be replaced.
7. Replace screen, rotor and cover. Install the distributor.
Checking the input of the breaker module for carbureted PRELUDE 1990 with HITACHI distributor
1. Remove the distributor cap.
2. Tag and disconnect the wires from the breaker module.
3. Turn on the ignition. Check voltage between blue wire and ground. There must be tension.
4. Check voltage between black/yellow wire and ground. There must be tension.
5. If there is no voltage on any test, turn off the ignition. Check integrity (conductivity) blue wire between ignition coil and breaker module. Check the integrity of the black/yellow wire between the ignition key, coil and breaker module.
6. Using an ohmmeter (Rx100 scale), check the continuity at the terminals of the breaker module. Conductivity should only exist in one direction.
7. If all tests are normal and the problem still exists, the breaker module needs to be replaced.
8. Install the distributor cap.
Interrupter Module Input Test for PrElUdE 1990-91 Fuel Injected Vehicles
1. The chopper module is located on the right front of the shock absorber. With the ignition off, disconnect the breaker module connector.
2. Turn on the ignition (ON position). Check voltage between blue wire and ground (earth). There must be tension.
3. Check voltage between black/yellow wire and ground. There must be tension.
4. If there is no voltage on any test, turn off the ignition. Check the continuity of the blue wire between the ignition coil and the breaker module. Check the continuity of the black/yellow wire between the ignition key, coil and breaker module.
5. Check continuity of white wire between ECU and breaker module connector.
