2001 Chevrolet Astro Battery Cable Parts Questions & Experts Answers

• Q: How to replace the positive battery cable and check for excessive resistance on 2001 Chevrolet Astro?

  A: You should use the j 39200 digital multimeter to check for excessive resistances within terminal connections and cable insulation before changing the battery positive cable. These issues might cause abnormal voltage drops that lead to hard starting problems. Start with safety measures by setting the transmission in park position then activating parking brakes and blocking the wheels. The battery distribution should be disconnected from the distributor to test voltage drops between three terminals: from the battery negative to the frame and between the battery positive to the Starter terminal stud along with the Starter housing to the frame when operating the Starter engine. Any voltage reading above 0.5 volts indicates excessive resistance which warrants the replacement of frayed cables or cleaning of connections and replacing corroded clamps. All electromechanical leads connected to the battery and the Starter must be disconnected first before removing the cable itself. Position the new battery positive cable like the original when installing both the rwd and a4wd configurations. The inner nut on the Starter solenoid requires proper tightening before attaching the Battery Cable to avoid any damage. The process of tightening includes 9 n.m (80 lb in) for the Starter solenoid nut and the underhood electrical center lead and 15 n.m (11 lb ft) for the battery positive terminal bolt.
