Mostly good power after Univolt was replaced...

After replacing the Univolt in my 1981 Excella 2 with a Parallax 7400. It was easy to swap this in and everything worked. I have to figure out how to rewire the Power On light and control panel but there is info on this forum for that. If anyone has a step by step for rewiring the Power On light for someone with just enough electrical experience to do this, I would appreciate getting it.

My issue is that even though the converter is supplying the right amount of power, a 12 volt car stereo that I installed will not work. It blinks on and off when I connect the power or it blows one of the inline fuses. Why would the fuse inline for the stereo blow and everything else in the camper work fine?

Check your polarities and be sure that all the grounds go to negative and all the power feeds go to positive. Also look for a short to ground in the wiring somewhere in the circuit. Take the inline fuse out and check the feed wire with a 12V test light or meter and verify that you are getting +12VDC in that wire.
