Claims

1. AN ELECTRICAL SYSTEM, COMPRISING:

RECEPTACLE MEANS FOR REMOVABLY CONNECTING A BATTERY INTO AN ELECTRICAL SYSTEM;

A FUSE ELECTRICALLY CONNECTED IN SERIES WITH SAID RECEPTACLE MEANS;

A UNIDIRECTIONAL ELECTRICAL PATH IN PARALLEL WITH SAID FUSE AND SAID RECEPTACLE MEANS;

A BOOSTER BATTERY;

NORMALLY DISABLED MEANS FOR ELECTRICALLY CONNECTING SAID BOOSTER BATTERY ACROSS SAID FUSE;

AND MEANS RESPONSIVE TO FLOW OF ELECTRICAL CURRENT THROUGH SAID UNIDIRECTIONAL ELECTRICAL PATH TO ENABLE SAID NORMALLY DISABLED MEANS, WHEREBY ELECTRICAL CURRENT FROM SAID BOOSTER BATTERY CAUSES SAID FUSE TO BURN OUT.
