• Q: How to replace the positive battery cable and check for excessive resistance on 2004 Chevrolet Astro?

  A: To change the battery positive cable, use the j 39200 digital multimeter to find out if there is high resistance due to improper terminal connection or cable insulation damage that might cause abnormal voltage drops, leading to hard starting. Start by making things safe by putting it in park, applying parking brakes, and blocking the wheels prior to cutting the battery feed at the distributor. Once the Starter is engaged and the engine is not running, we should measure the voltage drop between the ground and the frame of the car, between the battery post and the Starter terminal stud, and also between the Starter housing and the frame. However, if any drop of 0.5 volts is exceeded, clean the connections, and replace old frayed cables and corroded clamps with a more recent yet of the same circumference length. Before unhooking the old cable, remove battery positive cable bolt from battery, the connection from the Starter motor, and other links to the electrical convenience center. For installation, on the new battery, the positive cable, rwd as well as the a4wd vehicles, align the new battery, and make sure to tighten the inside nut in the solenoid battery terminal before linking the Battery Cable to protect the cables from breaking.
