Question about 1984 Chevrolet Impala
One device used to protect electrical components from burning out due to excessive current is a circuit breaker. Circuit breakers open and close the flow path for the electricity rapidly in order to protect the circuit if current is excessive. A circuit breaker is used on components which are more likely to draw excessive current such as the breaker found in the light switch that protects the headlight circuit. A separate 30 amp breaker mounted on the firewall or fuse block protects the power window and seat circuits, as applicable.
A fusible link is a protective device used in an electrical circuit and acts very much like a standard fuse. The major difference lies in that fusible links are larger and capable of conducting a higher amperage than most fuses. When the current increases beyond the rated amperage for a given link, the fusible metal of the wire link will melt, thus breaking the electrical circuit and preventing further damage to any other components or wiring. Whenever a fusible link is melted because of a short circuit, correct the cause before installing a new one. Most models have four fusible links.

Some how you may have got water up under the engine where it could have in 1 in a million shorted some of your wires. I would check your connections under the hood first. If you have a volt meter. I would check the battery to make sure your still getting 12.9V from it. But what your talking about seems like a short in you car to me. Good Luck!

If your security lights isnt turn on, the next thing to check is for power on the small stud at the starter with the key in start. If there is power on that stud then you have a bad starter or the cables and connections are faulty.
If you dont heard any "click" when turn the key, I'll think that isnt the security system, sound to me like a problem with your starter itself or ignition switch. Try testing the ignition switch and if that doesn't work take a look at the relay.
Additionally, check ground connections.
