If the ram unit is fitted to the starboard side, it operates as normal. If it has to be fitted to the port side, pull off the control knob, rotate it degrees and replace. This also goes for a later model with a control knob on the actuator ram unit. Somewhere in the attic is a spare mounting bracket - somewhere. It has a compass rose on top. I hae located manuals for the pushbutton units including the ut I have yet to discover written which looks like my unit.
It would be particularly useful to obtain some circuit diagrams as there is a fault on the equipment - specificallt that the 'manual jog' lever on the top of the remote cylindrical unit will only cause the arm to extend, not to retract. There was already an oter mounting point fitted on the combing and after measuring the maximum extenxion of the arm I see I will have to fabricate or obtain one of the extension inserts that were sold. Any ideas as to the thread? Regards Tony. The unit in question is an Autohelm , it is what was refered to as an analog model.
If you get a screwdriver under the central label there is a scrw which will release the dial, then another two crews underneath. Nordictrack Ifit Hack. The compass is trapped between the upper circuit bpard and top case so will fall out when you open up. The jog switches used to just stop working, they are micro switches and can be bought from the usual sources. If you power the unit up and the short the contacts with ascrewdriver i should drive one way and the other switch the other, this will prove if the switch is definitely duff.
If shorting the switch does not work then there are a number of IC on the upper pcb that control the compass and the jog control. It has worked reliably for years but this year on launch it is not working. There is power to it. So the manual would be very helpful, along with any experience you have in repairs. Also, do you know what type of bit is required to remove the screws.
Where I am, I have never seen that type of screw. Many thanks. Joined 27 Aug Messages Location Dartmouth. To open the case you need to lever off the compass disc or make a hole in the centre to access the retaining screw.
Mark the position of N first. The switch is a collet knob so you lever out the centre plug and use needle nose pliers to unscrew the collar. The screws in the base should be plain slotted screws. I can probably dig out some information on the string routing if that is the problem.
The only problem I have had is the power transistors have a tall brass heatsink and while motoring this must have resonated and fractured the solder joint. I replaced the heatsinks with lower profile aluminium plates. If you need more information ask and I will try to find some photos and a circuit.
I also have one of these that needs a new power switch, and they are fantastic. No, sorry I can't get better images. All those files were found on internet when I was looking for information for my own old tiller pilot. Seeking - Autohelm Service Manuals.
