It seems like my power cuts out for a second while driving. The car will still run but everything (radio, lights etc) cuts off for a second then restarts. This is getting annoying.

Other times the power cuts out after I just parked, then remains off. I have to unhook the battery terminals and re-attach them, then the power comes back.
I thought maybe there was a loose battery terminal, so I just redid all of those connections but still no change.

The only recent work has been replacing the a/c compressor.

Any help?
thanks in advace

 

There is a Black wire that goes from the battery to the engine fuse box. Make sure this connection is solid and also check below the fuse box where the Black wire is as it mates to the front harness.



EDIT: Also check the other end of the battery cables(not at the battery) as they both (+ and-)connect to the starter.

 

IF you worked around the a/c compressor, then maybe you knocked loose the connector that feeds the ignition switch. ITs a single black wire with black connector about three to six inches inbd and below the engine bay fuse box.
