My car lost all electrical while on the freeway today, lights and everything. Got a tow home and then it started up. Obviously an intermittent connection somewhere. Besides battery connections is there anything else that could cause total electrical failure?

Thanks for everyone's help.

 

yes, that happened to me one time. my lights started to dim and eventually the car died. it was some dam sensor that plugs in to the top of the alternator was disconnected, that was it, i couldnt believe it

 

Try checking for a loose connection at the starter. A lot of things get power from the big stud on the starter.

 

Hi Everyone, found the problem. One of the 12v lines off the big lug on the starter had broken and was grounding out intermittently on top of the starter. Thanks for everyone's help.
