Fifth Avenue - ignition kills electric circuits

Mike

But when I attempted to start the car, same thing happened. All electricity was cut to the radio, windows, etc.

There are two power circuits that go from the ignition through the connector on the firewall. Sometimes some of the individual pins/connectors get tired. I had this happen twice on different vacations. Fortunately I had a voltmeter and my service manual along and I did a fix. Actually a bypass wire until I got home and put in the proper replacement parts. The AC blower and compressor was the culprit. At the time I also added a high output alternator. I should have done it before.

How old is your battery? Sounds to me like it could well be the battery is bad. When you say the electronics all fail, this could just be the symptom of a battery dropping to a very low voltage when the starter is drawing high current.

I'd attempt to jump start the vehicle and if this works, I'd suspect the battery and/or charging system.

Good luck.
