I have a Mobile Authority Model 810ZX 35 amp 12vdc power supply that is
putting out almost 24volts now...
It has a variable power control and it does not change the output at all.
Unit was working, then when I turned it on, my radio lit up real brite.
I am glad it did not hurt the radio.
Could it be that the 4 transistors in the back went bad? MJ15015
Any help would be great...
Please e-mail me direct at


Thanks in advance...
