Mega PSU
Posted: Wed Jun 27, 2018 10:46 am
I was just playing with my stuffed Mega4 and have something weird going on. I bought another PSU, I needed one anyway. It is doing the same as my other one which I swapped for a ST supply. Clearly I didn't investigate it enough. No load, fan spins and does its business. If I hook it up to the Mega4 then it acts like a short on 5v.
However, if I hook up the CDrom PSU I hotwired the molex plug up for the ST and it kicks the Mega4 board over. If I check continuity on the motherboard between 5v and Gnd it growls short.
I will gut the repaired Mega and check when I get a chance, at least one working unit is a good yardstick. Any thoughts?
