Acura Integra 1989-1993 Electrical Specifications

The alternator in the 1989-1993 Acura Integra typically outputs between 13.5 to 14.5 volts when the engine is running. This range ensures proper charging of the battery and operation of electrical components.

The factory battery for the 1989-1993 Acura Integra is rated at approximately 45-50 Ah (Ampere-hours) with a cold cranking amperage (CCA) of 400-450 amps, depending on the specific model and trim.

To troubleshoot a blown fuse, locate the fuse box (typically under the dashboard or in the engine bay). Use a multimeter to check for continuity across the fuse. If the fuse is blown, replace it with one of the same amperage rating (e.g., 10A, 15A, 20A). Always identify and resolve the underlying cause of the blown fuse to prevent recurrence.

The headlight circuit wiring in the 1989-1993 Acura Integra typically follows this color code: Low beam - Green/White wire, High beam - Green/Red wire, Ground - Black wire. Always verify with a wiring diagram specific to your model and trim.

To test the ignition coil, disconnect it and use a multimeter to measure the primary resistance (between the positive and negative terminals), which should be approximately 0.6-0.8 ohms. The secondary resistance (between the positive terminal and the high-tension output) should be around 12,000-16,000 ohms. Replace the coil if readings are outside these ranges.
