I've got a '91 Honda Accord as my DD and new electronics that plug into the lighter socket will not work. I've got an old CB and a really old radar detector that work fine, but new cell phone chargers, a new radar detector, and other new electronics will not power on. I've cleaned the contact surfaces and tried twisting the power plugs on new items around trying to find a sweet spot, but no luck. Do the power cords or plugs on new electronics differ somehow from the older ones? Comparing the older plugs with the newer ones, there doesn't seem to be much visible difference as far as location of contact points goes.
