Hello there and welcome to Just Answer. My name is ***** ***** I will be assisting you today. I am an engineer with over 30 years of electrical and electronic training, repair and installation experience. I will try and answer your question accurately and precisely so that we can get you on your way.

I need to gather some more information from you in order to help: Do you have a multimeter or voltage tester?

Customer: replied 8 months ago.
I have a circuit tester
Expert:  Steve G. replied 8 months ago.

Ok, for the three lights that are not working, do you have 120V at each transformer?

Customer: replied 8 months ago.
not sure how woul d I know
Customer: replied 8 months ago.
my circuit tester just tells me I have power
Customer: replied 8 months ago.
why would they all work last week and not now
Expert:  Steve G. replied 8 months ago.

If there is power at the primary side of the transformer, then you have one of two things happening: a) the lamps are bad or b) the transformers are bad.

If you had a multimeter you could check the secondary voltage (12V??) at the lamp holder.

You can pick up a cheapy meter from Lowes or HD for about $20. That would be my best suggestion. Once you have it, we can continue.

Expert:  Steve G. replied 8 months ago.

That's a hard question to answer. Have you tried swapping lamps from non working to working lights?

Customer: replied 8 months ago.
Expert:  Steve G. replied 8 months ago.

Then if you have 120V at the bad lights, (and a good neutral also) it has to be the light itself - possibly the transformer.

We can't do much more without a meter I'm sorry to say.

Customer: replied 8 months ago.
Ok fair enough
Expert:  Steve G. replied 8 months ago.

If you get hold of a meter, let me know and we can do some tests.

Have a great weekend.

Expert:  Steve G. replied 8 months ago.

Excellent. I did mention that. I'm glad you found it.

Good luck and have a great Sunday.
