Disable ignition and fuel and CRANK for up to 15 seconds. 14 sec Disable the ignition by removing the high tension coil lead from the distributor and connecting it to ground. Disable the fuel pump to prevent unburnt fuel damaging the catalytic converter by removing the fuel pump relay or fuse. AutoTest automatically detects the start of cranking and counts down from 15 seconds to show the recommended cranking time remaining. 71

Time Volts Amps 5.0s s s The Starter Test Results Screen The results table shows the cranking volts and amps after 5, 10 and 15 seconds of cranking. When the amps readings are high, either there is excessive engine friction placing high loads on the starter motor or the starter motor is faulty. 72

Time Volts Amps 5.0s s s The Starter Test Results Screen The voltage readings can give an indication of the loaded voltage performance of the battery. If the battery is fully charged and the amps readings are around ½ the battery’s rated CCA then the voltage after 15 seconds is the battery’s Loaded Voltage (LV). LVs below 9.6 volts indicate a reject battery. 73

Time Volts Amps 5.0s s s The Starter Test Results Screen If the test battery was rated at 380 CCA (SAE) and it was fully charged for the test, the results screen above would indicate a reject battery. The test battery is delivering plenty of amps and will start an engine, but it’s voltage isn’t holding up under load, which indicates the battery will soon fail. 74

Time Volts Amps 5.0s s s The Starter Test Results Screen When cranking is stopped before 15 seconds (in this case just after 12 seconds) AutoTest will display as much data as was gathered during the shortened crank. Had cranking stopped before 10 seconds (but after 5) there would only be two rows of results. If cranking stopped before 5 seconds there would only be one. 75
