Re: Autohelm ST4000 Plus problems

Please forgive my ignorance, people, but although mechanically minded ( I have just installed a new diesel engine in my sailboat - 35 ft Bruce Roberts), I am a complete beginner when it comes to Autohelm ST4000, which came with the boat and was probably installed over 15 years ago. To start with, when the engaging lever is up and I press +10 or - 10 on the control panel, the motor whirrs but the wheel doesn't turn at all, and certainly not the required 10 degrees + or -. This I take to mean that there is a clutch or a belt slipping inside the unit. Any tips before I start to take this thing apart to find the problem? Are there still parts available?....many thanks for your patience people.
