I just installed an Indi MK3 and plugged in the new CA-PSU to test things out and found that nothing worked.
I backtracked and pulled out the Indi MK3 and tried again...not even a flicker of excitement. I did wait before cycling power.
I thought I'd blown my A1200. Tried the second CA-PSU that I bought, still no joy.
Plugged in my A1200/600 PSU, everything jumped into life....phew, I thought, thank you to the big imaginary friend in the sky.
I plugged the Indi back in and it too works with the older PSU.
Where do I start looking Jens? This is a little baffling.
I've just reshuffled my man cave and haven't set up my scope yet, but I'm guessing the CA-PSU thinks there's a fault and is keeping my A1200 safe.
LED on the CA-PSU does not appear to even flicker at power on on both CA-PSU's.
Thanks for any advice
