Commodore 128 power issue?

[JoeG]

Yesterday (2/19/2023) I acquired a Commodore 128 after I saw that it was working. I think that the power supply got swapped out before I brought the 128 and a power supply home. The seller had multiple 128's and power supplies. Two of the 128's just had a flashing power lights and didn't boot. At that point, I think (not sure) the power supply was swapped out as was the 128 to a third unit. The 128 booted and worked fine. So I think I got a bad power supply and not the one that was used to test the 128 I purchased since the 128 now only has a flashing red power light on it. I know that I have the working 128 since it was the nicest looking of the three.

Does anyone by chance know if a flashing light on a Commodore 128 is a symptom of a bad power supply, or other power issue? I'm new to the 128. Any help would be greatly appreciated!

The VIC-20, C64, Commodore 1902 monitor, Commodore 1571 floppy drive, Commodore CN2 Cassette, and the Apple IIc with monitor I acquired in the bundle all work fine.
