Ademco Vista-10SE

I've just took over one of my rental homes.

I replaced the old battery with a new one and had no AC voltage (16 VAC). I replace the transformer (tested the output before connecting it.

After I connected the tranformer to the control boad I noticed I did not have any AC voltage.

What would cause the AC transformer to keep going bad?

Thank you in advance for your prompt replies

Motherboard failure. A dead short in the AC to DC conversion circuit would do that. Replace the motherboard.
