Acura Integra 1985-1989 Electrical Specifications

The alternator in the 1985-1989 Acura Integra typically outputs between 13.5 to 14.5 volts at 2000 RPM. This ensures proper charging of the 12-volt battery and operation of electrical systems.

The recommended battery capacity for the 1985-1989 Acura Integra is 12 volts with a cold cranking amperage (CCA) rating of at least 450A. The battery should have a reserve capacity of 60-80 minutes to ensure reliable starting and electrical performance.

To troubleshoot a blown fuse, locate the fuse box (typically under the dashboard or in the engine compartment). 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 overload to prevent future issues.

The headlight circuit wiring color code for the 1985-1989 Acura Integra is as follows: Low beam - Green/White wire, High beam - Green/Red wire, Ground - Black wire. Always disconnect the battery before working on the electrical system to avoid short circuits.

To test the ignition coil, use a multimeter to measure the primary resistance (between the positive and negative terminals), which should be 0.5-1.0 ohms. The secondary resistance (between the positive terminal and the high-tension output) should be 6,000-12,000 ohms. Replace the coil if readings are outside these ranges.
