Swift DOHC
- To ensure power supply to power unit, disconnect primary wires connector at ignition coil. Turn ignition on. Using voltmeter, check voltage between coil positive terminal (Black/White wire) and ground. Battery voltage should exist. If not, check ignition fuse circuit. See Fig 1 .
- To check power unit resistance, turn ignition off. Remove power unit from under ignition coil. Tape together two 1.5-volt batteries in series to create a 3-volt power source. Install leads to 3-volt power source. Apply negative lead to "G" terminal and positive lead to "IB" terminal of power unit. See Fig 2 .
- Using ohmmeter, connect positive lead to terminal "G" and negative lead to terminal "OC" of power unit. See Fig 2 . Check for continuity with 3-volt power source applied to "IB" terminal. Check for NO continuity with 3-volt power source disconnected from "IB" terminal. See SWIFT POWER UNIT TEST table. Replace power unit if test results are not within specification.
