The alternator supplies all of the power needs for your 1995 Dodge Intrepid while the engine is running. A faulty alternator will allow the battery to be discharged until it can no longer supply power to the engine and the engine shuts down. A sure sign of a faulty alternator is the tell-tale “BATT” light displayed on the instrument cluster. Replacing the alternator in this car is a project that the average home mechanic can handle in under an hour, using basic tools.
Tools Used: Tools, Socket set, Metric wrench set, Screwdriver set
Change the Alternator
Disconnect and charge the battery while the alternator is being replaced. This will prevent premature failure of the alternator caused by trying to charge a dead battery. The alternator is designed to replace the charge lost during starting. It is not designed to recharge a dead battery.
Disconnect the wiring harness connector and large gauge power wire from the back of the alternator. The power wire is attached using a 10-mm nut that can be removed with a 10-mm wrench. To remove the wiring harness, squeeze the latch on the connector while pulling it from the back of the alternator.
Remove the two 15-mm alternator bolts from the alternator using a 15-mm wrench and a socket on a socket wrench. Lift the alternator from the engine compartment. Bolt the new alternator into place on the engine using the 15-mm bolts removed from the old alternator during removal. Tighten the bolts securely. Bolt the power wire to the back of the alternator, and plug the wiring harness into the alternator until it clicks into place.
Reconnect the battery, and start the engine. Check for proper alternator output. The “BATT” light should be off, and the voltage at the battery when the engine is running should be above 13.5 volts.
Tips & Warnings: Wear safety glasses when working around a running engine to prevent serious eye injury.
