  1. So I've been lurking here for nearly a year, initially trying to decide whether buying a boat was the right thing for us. But since I've now bought a boat and started asking questions elsewhere on the forum, I thought I should introduce myself! Our plan is to sell all our land-based stuff and move aboard in the next couple of months, and then to live off some of our savings whilst continuously cruising for a good few months. At least whilst we figure out if it really is what we want to do, and if so how to make it sustainable. I'm a digital artist by trade so freelance/contract work will always be available, but giving ourselves time to get used to a life afloat initially without the additional stresses of work sounds sensible. This is our boat btw, Tallymae. She's a 57' Tim Tyler hull from 2004. https://imgur.com/a/vUE6Qzg Expect many questions about 12V electrics and paint in the near future, since those are the major things we need to work on initially!
  2. So the boat currently has a Sterling 1500W inverter which I believe is as old as the boat itself (15 years). I've not tried using it yet but when we do, it's only going to be for evening entertainment etc, no plans for a washing machine or other similar high powered electrics! Going to try to embrace the 12V lifestyle as much as we can As with all these things, trying to find the answer to a question instead creates more questions! It sounds like the best option would be to get a new regulator / controller that allows us to combine the alternators to charge the leisure batteries, if we want to get the best from both alternators. But if that isn't going to give much improvement over just using the 110Ah to charge them (which aside from removing the not-very-idiot-proof rotary switch, is our main goal I think), maybe it's best to just connect the new one to the existing regulator and the old one to the and see how we get on with that. Moving on to the actual installation, am I likely to be able to find someone who can do the whole job or am I going to need a mechanic and an electrician? Currently moored at Willow Tree Marina in Yeading, West London. Thanks for all your help anyway!
  3. Yes, there are 2 separate isolators for the starter and leisure batteries. I would assume they are wired in a BSS compliant way, since it passed not more than weeks ago! That was the plan, but if it's possible to run both alternators (of differing sizes) in parallel, that does seem to make sense. I believe the boat was originally fitted with a split charge relay which caught fire, hence the previous owner removing it and installing the rotary switch! He was adamant that a relay was a bad idea, but perhaps a more recent one is going to be safer... Thanks for this info, so it sounds like the regulator is there to improve charging performance, rather than being an essential piece of equipment, since you don't say that I would need two of them if keeping the charging systems separate? Either way, it sounds like it's something else I should upgrade to a more modern version at the same time - if it will help improve charging performance.
  4. I don't think it's currently wired in that way though, since I still have 12v power when it is set to the OFF position. I think it is literally just connecting the alternator to their respective batteries.
  5. I have seperate battery isolating switches for both leisure and starter batteries. Do you mean that I will need additional isolating switches between the alternators and their respective battery(ies)?
  6. Hi! We've just taken ownership of our first narrowboat, so are currently experiencing a very steep learning curve regarding the electrics on board. The boat currently has (what I believe is) a 70Ah alternator, which is used to charge both starter and leisure batteries, but since there is no split charge relay it has to be selected by this rotary switch: https://i.imgur.com/bIuH5f3.png I'd like to do away with this switch completely since it seems like a really great way to a) forget to switch to starter battery before starting the engine b) forget to switch over after cruising for a bit to charge the leisure batteries c) accidentally switch to OFF and nerf the alternator. Luckily, the previous owner left a box containing a brand new 110Ah alternator, pulley, mounting brackets and instructions for installing alongside the existing one, which I believe will allow me to do away with that wretched switch. Now, before I go ahead and start trying to find someone to install it for us, I wanted to ask if there was anything else we would need to get to complete this installation? If I understand correctly (unlikely) the "4 step alternator regulator" blue box also in that picture converts the alternator voltage to what the batteries need dependent on their current state of charge. Is that still going to be useable with the more powerful alternator? Will I also need another one for the starter battery? Thanks for taking a look! Josh
