Emergency Flashers start blinking when the car is not running.

Is there a test for that? Or do I have to take the column apart to find out? Another responded with possibly security alert. Theft guard is on. BTW thank you for your response.

Thank you, will check it out. And let you know.

Factory alarm system. The car is on jacks, a new fuel pump and fuel filter is being put on. Fuel tank is dropped and disconnected. I disconnected the negative battery cable. (After the flashers started flashing)
