Work continues on the Transformer and power situation. I began by sleeving the transformer connections to make them less of a mess inside the cabinet and then began wiring the ATX powersupply cable. I thought... hey; I'll just wired the ATX PSU into the existing wiring harness going into the machine. Keep in mind I designed the ATX PSU board to always power the ATX PSU when AC is supplied. So in effect right now; the Machine will always be powered.

The switch in the machine is AFTER where I tied in the ATX PSU - as the Noise Suppressor is only rated for 5Amps as is the cable feeding the main power switch. The switch goes after the noise suppressor. The existing switch is only rated for 5A... and ATXs can demand 15A on a fully loaded machine. So it's not as simple as just wiring the ATX psu after the switch. Gonna have to replace the switch and probably run a wire back to the ATX power cable.

So I took a trip to Lowes to get some 14gauge black wire to wire the hot side from the switch to the ATX power cable. I also stopped by Fry's Electronics to get a suitable switch which could handle the current. I ended up selecting a DPDT 20A / 125V... not because I needed 20A... but because they didn't have anything on the shelf > 10A.

I desoldered the old switch and replace it with the new... putting in a red and a black wire to tie in the ATX PSU. In effect; I've bypassed the noise suppressor on the hot rail. But alas; can't be helped right now as I'm out of time for TPF.


Here's the transformer wired up with sleeved power connections going into the backbox.
