Subaru 81601AE38A Battery Positive Cable Assembly

Periodically inspect the entire length of each battery cable for damage, cracked or burned insulation and corrosion. Poor battery cable connections can cause starting problems and decreased engine performance. Check the cable-to-terminal connections at the ends of the cables for cracks, loose wire strands and corrosion. The presence of white, fluffy deposits under the insulation at the cable terminal connection is a sign that the cable is corroded and should be replaced. Check the terminals for distortion, missing mounting bolts and corrosion. When removing the cables always disconnect the negative cable from the negative battery post first and hook it up last or you might accidentally short the battery with the tool that you're using to loosen the cable clamps. Even if only the positive cable is being replaced, be sure to disconnect the negative cable from the negative battery post first. Disconnect the old cables from the negative and positive battery terminals, then disconnect them at their opposite ends as follows. Disconnect the ground cables from the left fender and from the transaxle. Disconnect the positive cable from the alternator and the starter solenoid. Note the routing of each cable to ensure correct installation, then detach any cable retaining clips or clamps and remove the cables. If you are replacing either or both of the battery cables, take them with you when buying new cables. It is vitally important that you replace the cables with identical parts. Cables have characteristics that make them easy to identify. Positive cables are usually red and larger in cross-section; ground cables are usually black and smaller in cross-section. Clean the threads of the starter solenoid or ground connection with a wire brush to remove rust and corrosion. Apply a light coat of battery terminal corrosion inhibitor or petroleum jelly to the threads to prevent future corrosion. Attach the cable to the terminal and tighten the mounting nut/bolt securely. Before connecting a new cable to the battery make sure that it reaches the battery post without having to be stretched. After installing the cables connect the negative cable to the negative battery post.

First, disconnect the negative battery cable, and then the other sides. Securely attach and tighten the cable to the solenoid or ground. Ensure the new cable reaches the battery post without stretching. Connect the cable to the positive terminal first, then the negative.
