[ICOM] ICOM PS-125

[Larry Young]

Peter:If the the PS-125 LED lights and the fan operates, then the supply is operating and is putting out +13 volts, as both operate from and  are connected to the +13 volt DC output of the supply.  If you download the service manual, and look in the upprt right  corner of the schematic, you will see this.You will also notice that CN11 & 12 are the positive output terminals and CN13, 14 are the negative output terminals. I would recommend you verify with an Ohmmeter that the ends of the PS output leads do indeed connect to CN11, 12,  and CN13,14.

Hi Adam,
As last ditch effort to send the PS-125 in for repair, I opened it up to verify that the slip on connectors on the 12VDC power cord are intact. The 12VDC power cord ohms out o.k and slip on connectors fit fine and tight.
I do not have any voltage at the slip on board. The power light comes on, so will the fan, if the PS warms up enough. Do you have any idea what to look for? Can you recommend a repair facility other than ICOM, to cut back on the turnaround time? Any suggestion is aprechiated. I like to have the PS back and working as soon as possible.
73,
