Hmm... Not enough power... You need to check this: with a multimeter, read the levels of the +5 and +12V lines. Less than 4.85 (in the +5V line) will stop the Amiga to feed the logic circuit.

Less than 10.5V in the 12V will stop the SCSI to function properly. In the SCSI section: check the terminator you have (probably in the HD circuit board). Active termination need more than 11V to act normally.

Also move JP300 ("tick" source in the motherboard) to the "EXT" position (2-3).

Re-check all cables, it's a common mistake. Sometimes ppl simply mismatch the connection.

Report your progress!
You Mean JP350?
Also I have an Amercian 125W PSU and I'm using a 250W stepdown transformer will that have any affect? did i get the wrong size tranformer?
