Urgent Advice Needed - BAS 423

RE:BAS 423, Built June 1994

During Initial Start Up, Frame Check Sash now barely moves.
It CREEPS , EXTEMELY Slow, but eventually does finish the Start Up Frame Check.

Pressing CLEAR at Start Up, Turning Off/On numerous times does not clear issue.

Is it safe to try and use machine?

I don't have a Owner Operator or Tech Manual, so have no idea what's up.

Thanks but have that data, doesn't have detail schematic board data.

Need Schematic for all Boards.
Need to find out correct Test Points and Voltage for each Board.
Need to know Board Part Numbers.

Issue:
Pantograph/Sash Power Up Movement Extremely Slow, creeps.
Pantograph/Sash moves freely when off.
Moves as it should using Arrow Keys once it Powers Up.
Control Box allows one to load design, assign color/needles but will not Confirm Frame Check Design nor does it begin sewing when START pushed, keep getting redundant Message: START TRACE, YES>START NO>CLR

Brother Tech thinks maybe PCB and/or PMD (pulse motor drive) pcb may have been damaged. not sure of Test Points and/or Correct Voltage.

Tap set at 240V.
Outlet In/out 248V
At Power Switch 124V each side, Top 248V.
Everything present as intact, no loose wiring.
Encountered issue while doing a test sew out on Head One, design had multiple Stops/Trims/Thread Pull Outs, aborted the sew out because of same.
Unplugged Head One and turned it off, enabled Head Two & Three, Rebooted, Clear same issue. Tried loading a KNOWN DST file that sewed just fine on machine earlier in day and others from past, keep getting same reduant message: START TRACE.

Any assistance, ideas are greatly appreciated.

First indication of machine problems was when I attempted to use MEND, Stepper Switch would not function at all.

Has anybody ever gotten redundant Error Message:

RESTART TRACE?
YES>START NO>CLR

When they attempt to Run a design?
Disk is Read, Allows Needle Set but can not CONFIRM nor START sew out, keep getting
RESTART TRACE error message, hard reboot, CLEAR, result in CREEP speed frame check.

After Creep Pantography/Sash Speed at Start UP Frame Check

Anybody ever had to replace the AVR Regulator (Power Supply)?
