What is your question?
Intermittent Electrical Problem. The car works fine , but about once a year it has this problem. When you go to crank the car it does NOT have any instrumentation lights, no gauges, no wipers, no radio, no cigarette lighter, and does NOT let the alternator charge the battery up. I have changed the alternator and battery, the key switch, the electrical switch on the bottom of the ignition switch, and the instrument cluster. What else could be the problem ? Possibly the ECM or ECU ? I do NOT have a wiring diagram to see how everything is wired after the key switch. This has been going on for about 3 years now. Thanks for any and all of the help. Mark

Hello, not an "ECM or ECU" problem. Have you checked the wiring connector at the alternator? Sometimes that connector has overheated, causing it to have terminal damage and melting at the connector. Worth looking at.
