Help with a Pentair intellibrite 5g

Brand new to the forum. Have a pool with 2 intellibrite 120v 5g color lights #601002 in sync (single 120v supply) Came in search of some help. I've read a decent amount about the board going bad and figured I'd dig into it before I just replaced the whole assembly. I spoke with a pool repair guy who told me to check the 120v to 12v converter built-in to the epoxy molding in the back case of the fixture. When testing the red leads together coming from the transformer that clip onto the light board I have zero voltage AC. When I test each lead individually and ground to the can I show 11.4ish volts. I verified I do have 120v coming into the can, there is just enough supply wiring at the surface of the epoxy to probe the supplies. Not really sure where to go next. I'm to the point that I'm kinda sure the transformer has failed, I should be getting 12v AC through the two leads that feed the board correct? Also is this repairable if the transformer has failed? I can't find a part number for that. I have no way to send 12v AC to the light board to test it. Any advice appreciated.

Welcome to TFP.

The internal transformer is not a Pentair replaceable part.

I thought I read that entire post but couldn't find the specific info I was looking for. Do you think that is what failed? I'm not sure if I'm testing it correctly or not. Definitely shows 11.5v when grounding to the can on each lead. But zero volts testing directly to both leads.
 
Ask your Pool Repair Guy what you are supposed to do if the internal transformer tests bad?
 
The person that told me to check it before ordering the board was actually with Florida sun seeker. I'll try them again. Pentair is closed for the holiday and my pool guy doesn't know the specifics on the internals of the light.
My point is that a Pool Repair Guy telling you to test something without telling you how to fix it is not very helpful.

Florida Sunseeker will tell you to buy new lights from them.

Pentair will tell you the light cannot be repaired.
 
So I wound up ordering this 120vac to 12vac 60watt led driver from Amazon for $22. Was able to solder it between with 120v supply barely sticking out of the epoxy resin and the board and it's working. Is this dangerous in anyway? Was going to do the copper plate heat sink mod also before I get a new lense gasket and submerge it.

I assume so. It's operated through the pentair control panel and has its own breaker and when I trip this GFCI outlet. The lights all go out.
Ok, then it is as safe as if you have a 120V light in the pool.
