Cut off the fat ugly cable. But leave Remove the rubber feet at the Just cut the cables short except It is easier to unsolder them short.
the protector.. we can reuse it. power end and remove screws ROF which can be soldered in Just grab with pliers. ...
Unsolder from the back side.. With a lot of care.. Pass the new cable through. Solder it to the points. ROF to GND
I then used some cable fittings Remove the wrapping from Cut through the goop with a Unsolder them.. Clean off goop.
Use what you have or just tin the old power supply,, short the small screwdriver. Tie 5v &Gnd before cut and reterminate
wire ends if you like. main caps carefully. if you don't want to unsolder.
Solder on extensions.. up to you Use a piece of terminal strip. Ensure voltages are correct.. well before of course.
Easy to know voltages..
5wires =Gnd.. 4wires=5v 1wire =12v
To make it absolutely clear.. here is the board shot with correctly color coded plugs.
Standard computer code.. Red 5v.. Yellow 12v.. Black.. Gnd.
The wires can twist up.. please check sata power pinout if unclear. In its correct position, 12v gnd 5v gnd
If you cut the wires from the original supply wrap red tap around the bundle of 4 wires before you cut.
Wrap black tape around the bundle of 5wires before you cut. It makes it easier than sorting out 10 black wires after the event.
ROF means Remote On ofF .. it puts out a small voltage which is like standby in a computer. when shorted to gnd, marked RTN on the supply btw.. it will turn on the supply. This gives you a power switch if you wanted to turn your TC on and off.
I have not found ADP-30RB supplies of sufficient quality of late.. the ones I used to get from HK have been in poor to unusable non-working condition.
If you are in US they sell plenty on ebay locally and are probably fine.. but I cannot get them here at reasonable shipping cost.
I am totally into the type 3 repairs now and the kits I sell are all using 12v external power supply as these are better, cheaper, and far more readily available.
