Title: General power check fails
Post by: Constantin on February 25, 2021, 01:33:12 AM

Hello JP,

after successfully building the first MP573, I have problems with the second MP573:

The new module has no short circuit
The general power check only delivers 14.08 V DC between V+ and TP2

Can you point me in any direction?

Nothing to see here. I failed and reversed D4. Everything is working now that I corrected my mistake.
