Problem: Intermittent starting issue 4520
Symptoms: Key on, fuel solenoid pulls in. on move key to "start" Gages cycle and the tach gage starts "ticking" one a second increasing reading each time. No starter function.
Tests: Battery above 12 Volts holds voltage during attempt to start. Battery posts clean and tight Ground cable attachment sound. Voltage at starter terminal 6 volts.
Troubleshooting: Using a needle probe through insulation on battery cable , found 6 volts 1/2 inch from positive battery terminal.
Replaced end on cable and no more problem.
Examination of faulted part: The factory potted end looked good, but on cutting it open it had corrosion inside and was not making good connections. Many of the copper wires had deteriorated to nothing.
