i have a baker turret truck btma
i believe its a still mx20
it is the 93 version, i believe, with connectors 4a and 4b at the desk (square amp plugs not round plugs)
it has an lr8o steering control
the error at the control desk is:
"12volt nominal - voltage too low ??*"
i changed the 12v & 5v dc/dc converter in the central unit
where do i have to lose the 12v signal to create this error
the book is not very clear on what to do after transformer swap did not work
