Is my F-amp bad

[Vet4HolidayLights]

So does any know if there is a way to test a f-amp without a f-tester? I have a string of lights that is out and I have checked the string and my extension that runs to it and they both work. I have also checked the fuse for that port also and it is good.

Thanks and God Bless

The way I would test the f-amp and put it between the controller and a known working prop to see if it still works or not. This will tell you if it is passing data and power enough to still drive the prop.

Is there a way to test it with a multimeter?

No, you would need a signal generator and oscilloscope - basically look at signal in vs signal out.
