Norstar CICS Dead

[Bilcor]

I have a Norstar CICS that I recently purchased which seems to be dead on arrrival. I purchased the unit from out of town and picked it up myself. I used one of the cards in another installation to get caller id on phones so I am somewhat ahead of the game. Anyway, when I plugged the unit in to test it, I find that the power led doesn't light up. When I check the power to the main board I find a very low voltage (about 1 volt) I have checked the fuse and it is fine. Is there anywhere I can get a schematic of the power supply board? I am thinking that the power supply is defective. Anyone got any ideas that I can try?

Thanks,

It could be a bad power supply. Also look closely at the CICS motherboard for burned out components.

Thanks for the reply Brian. I do suspect the power supply. I am hoping that someone may have a circuit schematic of the CICS so that I can track the voltage from the power supply to the main board. I see on the PS board a component listed as F3 that looks like a capacitor. I don't think it is a fuse as it checks to be open and is tied to the ground plane.

Easier to just replace the PS if you don't know what to look for on the circuits.
Part # NT7B6304

Only fuse is right under the 3 prong receptacle that I know of.
