Expert Reply:
The Hopkins Engager Push-To-Test Trailer Breakaway Kit # 20099 should not be draining the battery from your vehicle or from the breakaway battery unless the cable is pulled out. What could be happening is the breakaway Battery # HM20008 is unable to hold a charge and when connected to your vehicle it is trying to charge the battery which kills the vehicle battery. But when disconnected since the battery cannot maintain a charge it also dies very quickly.
If you still want to use a toggle use one like the Buyers # 337SW911 or a Disconnect # SE63FR use it on the ground(white) wire as this will be much safer than having it on one of the power wires.
