Autohelm Linear Drive

[Capn Dan]

I am considering upgrading the controls and compass for an autohelm 5000. The linear drive that I currently have has a control board inside of the linear drive, a 7 pin connector that goes to the control head, and two power leads that connect to the control board inside the drive. It is a pre-type 1 or 2 drive.

Does anyone know if the newer type 1 or 2 autohelm / raymarine linear drives use a circuit board inside the drive unit or do the four leads go directly to the motor and clutch?

Any ideas on the compatibility of the newer controls with the 5000 linear drive?

Thanks

raymarine.com has lots of manuals online, including many old ones. That's where I would start, looking at the install/wiring diagrams and seeing which autopilot computers are compatible with which drives. Hope it helps...

2 wires - the small ones, screened on ours, go to the clutch, the other 2 to the motor
