Does anyone have a working LENZE 534 controller and isolator board they can sell me at a reasonable price?
I am looking at retrofitting a more powerful DC Treadmill motor to My Boxford 160TCL and want to prototype external to machine first. I would keep Driver and isolator as a spare. I am not interested in converting to other drivers or BOB at this time.

I am thinking of scoping and publishing the board voltages and publishing them on this forum ...if anyone is interested let me know as there is no useful information or schematics for diagnosing problems at component level avail from other sources that I can find.
Thanks in advance.
John
