12v power supply putting out AC instead of DC

I discovered recently that my 12v DC power supply was putting out Ac. It is an outdoor type for landscape lights that has components sealed in a block of resin. ( here I thought I was lucky getting those led landscape lights in the right way each time lol). What I did was add a 20 amp bridge rectifier and heatsync to the output coming from this sealed block. 12v @ 15 amps

My question is, Adding this bridge rectifier to fix the failed one inside the sealed circuit a safe thing to do, or could it cause future problems because of the original failure?

Answer this question I have this problem too

Is this a good question?

Honey you should be okay with that for as long as you watch the heat and maintain your heatsink properly. It might be useful if you can provide us with the make and model number of the power supply.

Thanks for the reply. This power supply was not meant to be serviced as it was riveted together and all identifiable components are encased in a resin material. It could have been putting out AC for years and I would not have discovered the malfunction until I thought it would be a good idea to measure the output voltage before I added a pump to the load. The only reason I decided to repair it was because of how bulletproof it was for the outdoor environment.
