I have a ford 1.8xld with Bosch alternator, also the boat has a smith industries tacho, which has never been connected. I have searched and found links from other sites, as I understand it the Tacho is wired to ground and to the 'W' terminal of the alternator. See pics.
As you can see from the alternator picture, the 'W' terminal appears to be missing, I am assuming that I will have to connect my own terminal her, probably by soldering. Is this correct ?
The second picture is from the back of the Tacho. Assuming this is the wiring diagram, single ind is a single alternator setup, dual ind, for a dual alternator setup. So if I am reading correctly, 'W' connector from alternator, to pin 1 of Tacho, pin 2 of Tacho to Ground. And now if I wanted to connect the second Alternator, then the same for pins 3 and 4 ?
If any one can just confirm or deny, been a while ( 18 years ) since working on this type of equipment.
First post here so please be gentle! haha
OK, I'm literally weeks away from getting my 60' sail away. I will be a continuous cruiser liveaboard and regularly moving around the canal and river waterways. Engine is a Canalline 42 with 1x 50A and 1x 175A Alternators. I'm planning on getting a Webasto water heater/boiler too to compliment multi fuel stove.
I have done some sums and require around 120Ah a day for things like, 12v fridge, pumps, boiler, laptop, TV, lighting, phone charging etc. (Actual is 80Ah but I wanted a good amount of wiggle room).
I'm planning on filling my roof with solar and would like to use Victron equipment (apart from solar).
I'm planning on:
5x 285w Monocrystalline Solar Panels totalling: 1425w (It has an approx 42' cabin / roof space) 1x Victron SmartSolar 100A MPPT Solar Charge Controller 1x Victron BMV-700 Battery Monitor 1x Victron SmartSolar LCD display 1x Victron Multiplus 1600VA Inverter 70A charger 16A relay 12V I'd like to use solar as much as possible to power my needs but haven't decided upon batteries just yet. I'd like your comments on qty and type of batteries I'd need to keep everything tip-top, if I'll need a generator for the winter months (likely Honda EU2.0i using LPG). Is the above all too overkill or will I struggle in the depths of dark winter? I would like to use a washing machine every so often but if batteries would get hammered I can use Generator for that. (obviously not on hot washes). I'll be getting an electrician to do the install (apart from solar panels on the roof). Thanks Jono
Hi. Firstly, we are CC's with no hookup. I have a Victron 12/3000/120 inverter charger, Victron BMV602s battery monitor, 110amp alternator, Honda 1kw generator, Victron 30amp solar controller with 3x 100w solar panels. I have fitted 4x new Yuasa 115amp hr batteries. These are set as first set had faults within a few weeks (from Halfords are the batteries). When I charge the batteries from alternator, the BMV shows about 70amp initially and over a few hours reduces down to about 5-6 amp tail current. Charge voltage is about 14.3 volts. The BMV shows 100%. I always leave the engine running longer to see the tail current low as possible. I sometimes use the Honda generator to top up the batteries making sure they reach float status. Although the BMV shows say 70amps used since 100% charge and SOC still says about 90% charge, the battery voltage is down to below 12 volts. We have a 240v fridge freezer (new) running off the inverter plus some TV, led lights and phone charging, the actual current since last recharge (from the BMV) is correct I assume? Could it just be duff batteries again? Any ideas?

I'm sure everyone remembers my poor charging regime and the lengthy thread that ensued.
I'm still using my set of somewhat reduced capacity 4x110ah batteries - a couple hours engine running in the morning, a couple in the evening, and then switch off the 240v (including fridge) at night. This gives me enough laptop time in the evening, led lights and various pumps etc.
So, for now carrying on quite happily - but I have noticed a new phenomenon creeping in lately.
Today for example: I ran the engine for an hour or so when I got up (with 240v back on as normal). I then cruised for 3 1/2 hrs. A couple hours later, and my batteries are already back down to 12.3v so I have fired up the engine again.
What I am saying is this - it would appear that the leisure batteries are not getting much (or any?) charge when I'm cruising. I can't think what this could be but I'm sure someone will enlighten me - be gentle!
Just to re iterate - I know the batteries have reduced capacity, but a couple hours charging off the engine normally sees them up to say 12.8v which lasts all day or all evening. Even on longer cruises, they don't seem to get as much charge as when the engine is just running in neutral.
I have two alternators, 50a for engine, 175 for leisure.
We currently have 3 x 125ah leisure batteries powering the fridge, lighting (mostly LED) and water/waste pumps. The bank is charged by a single solar panel through an EPSolar MPPT charge controller. This was fine during the summer but with winter fast approaching we are finding that come the morning there isn't enough juice to power the pumps for a shower. We are mostly marina based so would like to add in a mains charger to top up the batteries once night falls. Electricity is metered so would only want to charge from shore power when necessary. Currently we achieve this by attaching a car battery charger using crocodile clips - it works but isn't a viable long term solution. The charger only has trickle or fast charge and is manually selected. I was also a little wary that I might be sending current to the solar panel instead of away from it, but it hasn't blown up yet
So, my questions are:
Is there such a device available that I can connect both the solar and a 240V charger to and it automatically selects which input to charge the batteries with, prioritising the solar? Maybe even with automatic health programming to allow the batteries to discharge periodically to keep them healthy? Failing that, if I just get a decent 240V charger that automatically switches charge mode, will there be any problems permanently connecting that directly to the batteries in addition to the solar, and just turn it on when required? Or should I connect them via, say, a rocker switch to manually change from solar charging or 240V charging? What fuses would be required? Can someone recommend a decent multistage 240V charger?
I'm sure I'll think of something else as soon as I've posted this, but it will do for starters :-) Thanks in advance.
