Downunder you are legend..  :13: I'll take another look at it today.. only thing I'm thinking about is the pin on the opposite side.. is it needed? Reads 1v or there abouts.. Need to take a look to see where it's  going.. Any ideas?  :c017:

downunder:
L504 is shown only as a coil in the schematic, so I presume third pin goes to primary ground to allow the shielding to act as a radiation stopper, in which case it shoud read zero ohms to the -ve of the main ripple filter C508 - 100uF.
BTW. There is also a current sensing resistor R531 - 0.15 ohms that goes to pin 3 [i.sens] of IC301 via R521.
I presume that reads fine when unit is cold.
I googled the power supply part number to locate the schematic

SlyAKs:
Cheers again... Tried bridging the two pins with continuity and it's blown the main fuse on the ps.. And it just so happens, I'm fresh out of fuses.. will be getting more tomorrow.. I just spotted another ps on eBay for £23 so I think I'm gonna grab it before its sold! Cheapest I've spotted anywhere by £20. Still want to get to bottom of this though.. appreciate your input so far Downunder..

downunder:
Well that's taken me by surprise. Ah well, at least with another board, you'll be able to experiment.

SlyAKs:
New power supply done the job... Cheers for all your help Downunder.. Much appreciated!
