In a 1994 Grand Marquis what could cause a failure in the instrument panel lights and tail lights if no fuses or high current fuses or circuit breakers are faulty?

Check the headlight switch and make sure you are getting current out of the switch when you turn on the lights.

Circuit breakers are used for what?
Circuit breakers prevent excessive current from flowing in the circuit by "tripping" when the current exceeds the circuit breaker rating. This causes the current to be cut off, and is used to protect the wiring as well as the appliances.
What does tripped circuit breakers indicate?
That something in the circuit has pulled more current than intended.
Do you have a circuit breaker which operates for one millon volts?
Circuit breakers operate on current not voltage.
What do circuit breakers and fuses have in common?
Both fuses and circuit breakers cut off a circuit from its power supply when the total current through the circuit exceeds the current rating of the fuse or circuit breaker, usually due to a short to ground or overloading of the circuit. Both use materials that respond to heat.
How many outlet for ELECTRIC circuit in a house?
As many as you like but the total current taken is limited by the circuit breakers.
What devices are used to deliberately create an open circuit when the current exceeds a specific value?
fuses or circuit breakers
Is an unbroken path through which an electric current can flow?
The term is "circuit" (from the same root as circle) An electric circuit must be uninterrupted for the current to flow. (This is why circuit-breakers are also called circuit-interruptors.)
What circuit protector?
It is usually classed as a device that will open the circuit if the current in the circuit goes high. Two examples of these types of devices are fuses and circuit breakers.
Is a circuit breaker an alternative fuses?
Circuit breakers do the same thing as fuses. They interrupt current flow when a certain preset point is reached. The difference between circuit breakers and fuses are that circuit breakers are resettable and reusable, whereas fuses are one time devices that must be replaced after they blow.
What is the 'job' of an ammeter in a circuit?
It measures the current.
What do tripped circuts breakers and blown fuses indicate?
That something in the circuit has pulled more current than intended.
What happens when two circuit breakers are parallel?
There are 3 cases in C.B. paralleling: 1. Both Circuit breakers of same current ratings with same time settings. 2. Both circuit breakers of different current ratings 3. Both Circuit breakers of same current ratings with different time settings. Case1: Any of the C.B.trips (depending on CT characteristics as no two CTs' can have same characteristics) Case 2. The one with lower current ratings would trip first. Case 3: The one with lower time settings would trip earlier.
