I have a Sundance 880 chelsee 2011 and I have no power at the display and the breaker doesn't trip. I have a transformer that goes to the circuit board that says it's supposed to be 12v but it is showing 5 volts. I purchased a new transformer and the new one also said 5volts. Also attached to the transformer wires was the led light panel for the tub so I disconnected it and the transformer then showed 8 volts now the highest I have Read. I have power to everything in the tub and the fuse is fine on the main board. What is causing this?

Do you have 120V AC going into the transfomer? How are you testing what's coming out of the transformer? Believe you should set meter to DC and test the two leads coming out of trans. Don't test anything to ground.
Shouldn't be DC coming directly out of a standard transformer. That's usually AC all the way. You get DC after putting the transformer output into a power supply or into a bridge rectifier. If it's a walwort, there should be info on the output voltage and type molded in the case or on a label. That could already have the bridge rectifier built into the wallwort and then you would be testing for DC.
Not knowing what type of transformer the poster has makes it harder to tell him how to set up to test.

The transformer takes 120 ac to 12v ac but the old and new transformer is showing 9 volts out roughly after I unplug the lights from the control panel. If the lights wire is hooked up the transformer then reads 5volts
Sorry for the bad info. I think I was thinking about the coffee machines that I used to work on that had power supplies. In my mind they sort of do the same but only a PS changes from AC to DC.
