Grinch and Ren-c power problems

[ulto]

I set up my new grinch and Ren-c combo last night, and everything was working properly. I just got home and was going to test it again, and when I checked the grinch power led, it was flickering at a constant rate. The Ren-c also had a flickering Led, and the Heartbeat wouldnt turn on.

Does anyone have any idea what the problem is?

Sounds like low voltage. Check your wiring and you power supply feeding your grinch/Ren-c combo.

I would have to agree with Rich, sounds like power supply issue. What kind of supply are you using?
