Hi guys, been a while.
In my absence, I've actually been quite busy. I've been sorting out alot of my old Mac 68K (and a few PPC) machines and over the past few years, bringing them out of storage with mostly positive results.
However this IIvx (I know, hardly one of the 'good' ones but I kinda like it in it's own way), doesn't want to power on, as in at all. This was working prior to storage too. So, the first port of call was to replace the PSU with a known working unit (from a Quadra 650). Still nothing, soft or hard power.
I know there is power going to the PSU atleast as I hear a small snap of electricity as the 'kettle' style lead is inserted. It could be my imagination, but I'm sure I sometimes hear a micro relay switching too sometime when power is applied (or atleast attempted).
I know the PSU is good, hell I think it's original one is working too. The 6 pin 'chocolate' block connector is definitely making contact with the female connector on the motherboard.
This has completely stumped, anyone have any idea where I should look or if there's any tests I can make? O do have a multimeter on standby.
