• Q: How Can Excessive Resistance in Battery Cables Be Addressed on 2000 Chevrolet Astro?

  A: Poor terminal connections causing excessive resistance and partial short circkuit through worn insulation on cables, can cause abnormal voltage drop in starter cables resulting in failure of normal starter function causing hard starts. When replacing the battery cables, a comparable cable of the same type, diameter, and length to the original cable should be ordered. Some of the positive cables are likely to have additional feed wires, and some of the negative cables will have extra ground leads. To test the system, create a ground connection between the negative of the battery attached to the frame with the help of a probe and the J 39200 Digital Multimeter (J 39200) to check for a voltage drop between the ground (the negative terminal of the battery) and the frame while starting the starter with a probe. Also, include examining the voltage drop between the bottom of the battery posts to the starter terminal stud and also between the housing of a starter to the frame while the starter was in operable mode. If voltage drop is more than 0.5 volts anywhere in any of the above checks, excessive resistance is in the circuit, which calls for disconnection and clean the cables and hook up. When cables are frayed or clamps corroded, they have to be replaced by using new cables of the same length and diameter as the original one.
