69 valiant electrical gremlin turn signal and license plate light
For example with one test lead clipped to a chassis ground, touch the other lead to the brass in the connector.
The tester should light up (when the parking lights are on).
If that works, remove the bulb and reconnect the socket and touch the other lead to the contact inside the socket.
Not seeing evidence of a ground short.
A short is when two wires touch and the electricity finds a shorter path to ground through the wrong device.
A ground short is when a wire touches a ground and electricty takes the the shortest path to ground avoiding all devices.
That's OK.
A few concepts will help get you grounded. Get it? grounded?
When we talk about electricity taking the shortest path, we're talking about electrons flowing.
For that to happen there has to be a complete circuit back to the power source.
The power source when the car is running is the alternator. Otherwise its the battery.
The circuit must be completed for the electrons to flow.
If its completed with no resistance, LOTS of electrons will try to get from high voltage to low voltage. (actually they move the other way, but that's not important for our purposes) That's when the weakest part of the circuit gets hot and melts.
The amount of electrons moving is measured in amperes.
The energy level is measured in Volts.
The test light can show you if there is power getting to the lamp socket.

Do you mean the dash indicator is blinking or on but not blinking?
