PM me with an email address. For now as to your error:BK-151
Fault Code BK-151, indicates that the 36V input is low.
Initial Actions
Check fuse F3.
Check the Voltage protection plug P7 on the interlock PCB. The resistance must be grater
than MOhm.
Make sure that contact P8 on interlock PCB is correctly installed.
Make sure that contact P12 on controller PCB is correctly installed
Make sure that the transformer in the machine is wired correctly.
Procedure
Measure incoming voltage on Rectifier (White and Blue). The voltage is approximately 26V?
Y N
Replace transformer
Measure outgoing voltage on rectifier (Red and Black). The voltage is approximately 36V?
Y N
Replace Rectifier.
Power off the machine. Measure between the black connector on the Rectifier and P6-3 on interlock PCB.
Is there continuity?
Y N
Replace wire Harness.
Measure between the red connector on the Rectifier and P6-1 on interlock PCB. Is there continuity?
Y N
Replace wire harness.
Replace interlock PCB.
I have also had the mount bracket for the cover interlock board bend down over time and caused the interlock circuit to not sequence properly.
