2003 Chevrolet Astro Battery Cable Parts and Q&A

• Q: How to replace the positive battery cable and check for excessive resistance on 2003 Chevrolet Astro?

  A: When switching the battery positive cable use the j 39200 digital multimeter to measure if poor connections and worn insulation lead to abnormal voltage drops or hard starting through excessive resistance detection. Safety must be accomplished first by placing the transmission in park position and activating the parking brake before wheel blocking. Check the voltage drops through use of the j 39200 digital multimeter between three points: ground to battery negative to frame, battery positive to Starter terminal and frame, and frame to Starter housing during Starter operation. Excessive voltage drops exceeding 0.5 volts require connection cleaning and replacement of cables with frayed wires and clamps with corrosion. The procedure to remove the battery positive cable requires disconnecting it from all connections between the battery, starter motor and the electrical convenience center. Position the new battery positive cable according to its original rwd or a4wd configuration when installing the cable by securely fastening the inner nut first at the Starter solenoid before connecting it to the underhood electrical center and finally securing the battery positive terminal bolt on the battery with 15 n.m (11 lb ft).
