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?
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.
