I'm no longer on the boat so can't measure it, but i'd guestimate about the size of your hand, fingers outstretched... Metric 😆

Your layout looks quite different to mine, so it will be a process of identifying the wires against the wiring diagram but the overall process should be similar once that is done

Are you referring to the voltage sensing inputs to the SX460? If so then I simply tee'd off from the back of one of the 240vac sockets and ran the wires to the inputs on the AVR. EDIT: on second look i actually used WAGO connectors to tee off from the output socket as I like them and they're reliable. @Lockkeeper7 Youre going to want to take particular note of this post, as the old markon AVR siphons extra voltage off, and the SX moderates it differently. I've included steps and a wiring diagram to explain here but you need to rejig the system slightly to work with the SX unit.

Ok got you. If you want to keep the Markon i'd try the SX option then, chances are it will sort it if no other damage to the unit had occured. Its a cheap option and could be worth a shot before replacing the unit with an alternative.

The install itself was relatively easy, but the research and working out along the way was a nightmare. Thankfully I documented everything in the thread linked above so you should have no problem following it after reading it through. Also happy to help with any questions if needed. What are the symptoms of your failing AVR out of curiousity?

Yup that was me. OP do you know if it is a Markon BL105 or an SL105? Nevermind, if it has an AVR then its got to be the SL model. I was able to to fit an SX460 to mine. Much more reliable, better output and cheap. 👌

It was, though we wanted to get an engineer over to give it a proper check-over anyway rather than just wing it ourselves.

Hi all, just an update. We has an engineer come and he said the solenoid was toast. He has installed a stop switch away from the engine now and the engine can be stopped remotely. In the future i'd like to have a cover made so the engine is not open but for now this should suffice. Thanks for all the advice. 👍

Yeah so the solenoid was dead apparently, we've had a pull stop installed and now able to stop the engine remotely. I'll update the main thread now.

Been using it for almost a month now and it has been doing a charm keeping the boat clean. It is set on a timer each weekday to vacuum the floors and carpet, it also has a schedule to mop each monday and friday. It has created a lidar map of my boat and separated everything into rooms so i can do single room cleans or whatever may be needed at the time. I've been monitoring the battery consumption and have noted it uses very little power from my bank to recharge, a full clean and mop of my boat only uses 10% of the units internal battery and it will be full again and idle within 30 minutes of docking at the end of a clean. I have a 200ah LiFePo4 battery setup and have haven't noticed any significant change to my power levels at all. All in all i'd recommend it for a boat with a reliable power setup and no major obstructions which would stop the vacuum from navigating the boat.

Not sure yet haha, got it scheduled for a full clean and mop 2pm every weekday. Will see how it goes, the magic want does help though

Now just to see how the ferrets deal with it...

So i got one and its doing a good job so far, but it will require a bit of fine tuning to get it perfect. It has mapped out the boat nicely, the pics below are just a sample run of it doing the saloon area. The configuration options are good and with some adjustments it should be a good little boat upgrade hopefully.

Hi all, sorry for my lack of info in the replies. We've got an engineer coming to have a proper look. A lot of these replies have been a little hard to fully decode and understand so i figured i'd get as much info as possible from this engineer before reporting back with details and hopefully the fix. I hope i'm not coming across as blanking or ghosting, i saw a post on another thread referencing my lack of response.. sorry 😅

Good call, cheers mate i'll do that and report back 👍
