[amsat-bb] Kenpro-Yaesu 5400 5600B question

Good day sat-guys: I have an old Kenpro G5400 without computer interface and a newer Yaesu G5600B control box. What are the differences in the motors between these 2 series other than the limit switches? In case of the control boxes, I see the G5400 has starter motor caps, but the G5600B control box doesn't. The old motors didn't work with the 5600B box until I added a starter cap to both the AZ and EL motor lines. I am planning to use the 5600B box with LVB tracker- any other issues? What do I need to do to use my old motors with the G5600B? Or, anyone have 5500 motors that they wish to sell?

Any assistance would be appreciated.

Thanks, Bennett ko2ok
