9v with 700mA limiter. Triggers overcurrent protection every time
I'm entertaining suggestions once more.....
C44 checks out at 100uF 0.9ohm ESR
+12V lead to where the +ve of C44 was
GND lead to -ve of C45
I got confident (not earned, as i'm a novice)
I reconnected R59, and removed R58 and TR5 - short gone
Reconnected R58, short returns (R58 checks out at 1K)
Removed C5-C8 - short remained
Disconnected R59 and C44 - current draw went to zero
Replaced C5-C8, current draw still zero
Suggests to me the issue still lay in the DC-DC converted board somewhere....
Where would you reccommend injecting 12V? Positive side of C44 goes to the +12V DRAM supply, Positive side of C45 goes to +12VA(Analogue supply) (or either side of R62)
Now to try and find some spare banana plugs to make up a jumper cable...
