Re: [electricboats] Encoder/Hall effect sensor issue

Yes thanks for adding that - good advice - I also bought two to keep one as a spare.

And the lightning strike is a strong possibility for my failure - hadn't thought of that.

Cheers

We had two encoders (ME1115 on two separate boats) fail after a close lightning strike last year at our yacht club.  It was a bit of a hassle sourcing and replacing them, but did not have to mess around with the software. 

I think it is a good idea to have a spare encoder around. The encoders detect very small changes in magnetism and translate them into a sinusoidal wave. The sensitivity to magnetism makes them susceptible to EMPs associated with lightning.

Hi John,

Yes I had a faulty encoder on same motor and replaced it a month or so ago. Replacement itself is very easy - remove cover plate, unscrew 4 hex screws and unplug at board. Installation the reverse procedure. Pictures attached.

More complicated is that it then has to be reconfigured using the DVT software for the controller - fairly complicated - Thierry Lequeu at kit-elec-shop.com in France did it for me via a remote screenshare connection.

Hope that helps.

(Original failed when I returned to the boat after the winter and the motor did not work - it rotated about 10 degrees each time the throttle was applied and a humming came from the SEVCON unit. Thunderstruck were unable to diagnose but Thierry Lequeu at kit-elec-shop.com in France solved it for me - highly recommend him for SEVCON or motor issues for anyone in France)

With some remote assistance on Sevcon parameter adjustment the motor has more power then before - pushes a 9 tonne Gin Fizz to 6-7 knots - very happy with it.

Good luck, Stewart

Installed both ME1616 liquid cooled systems and have Curtis code - throttle disabled because encoder sensor is not detected. Does anyone have experience replacing or repairing this part? If so, please share.

Thanks
