I am installing an Autohelm onmy Hunter 30 1991. I have come to the point where I have to find the power source and decide where to place the panel. It is not as obvious as I thought. Has anyone been through the same thing and if so please help with suggestions. Thanks John North

Autohelm 4000 on H30

My 1989 H30G is a basically similar model to your 1991. My Autohelm 4000 is mounted on the cockpit coaming on the starboard side, just in front of the starboard cockpit locker. The power/signal connector is inside the locker, where it is protected. The power leads come from the Instruments switch on the DC panel, and the control cable goes to the Autohelm motor on the pedestal through the conduit tube that carries the throttle and transmission cables. The Autohelm is the older model with the flux gate compass inside the control box, and this works well, with excellent steering both on the wind and off. BTW, I recently discovered that the fuel gauge mounted in the top of the fuel tank uses a powerful magnet to couple the position of the internal float to the indicator needle, so I would recomment keeping any type of compass as far from the top center of the fuel tank as possible. The internal magnet rotates as the fuel level changes, so there is no way to compensate a compass for its effects. Hope this helps.

Autohelm ST3000 on 30T

Installed Autohelm Wheeldrive ST3000 on my 1991 30T on recommendation of former Hunter employee who put ST3000 on his 30T. It works great. Mounted controls on side of cockpit on port side just forward of aft port cockpit locker. Chose port side as being farthest away from magnetic and iron influences. Power wire passes through conduit inside port lazarette to breaker on a secondary electrical distribution panel I installed above cabin nav station. Ground wire passes directly to negative terminal on battery which is aft on port side. I can furnish photos if you wish. Roy Mosteller SEA JOY (30T)
