Hi Kimberly. All the cooling fluid in the bilge? Check all hoses and hose connections, simple stuff. Connections to the heat exchanger. I would doubt it is a pump failure. Hoses do split, particularly when they are old. Hose clips can rust and hoses come off, O rings get old and fail.
Fill the coolant tank, run the engine sitting in the engine room and see where the coolant is leaking from. I recently had a coolant hose come off on my genset engine. Fortunately I saw the coolant sloshing around where it shouldn't be so it was no big deal/
Kind Regards

Hi all,

We have the Maramu #98 1981 with the infamous, invincible "Mr Perkins" engine, 4.154 M. Well, he's overheated on us  ( the alarm didn't sound and luckily my husband just happened tobe looking at the temperature gauge next to the helm). After replacing the cooling fluid, and motoring a short time to get to safety, the next day all the coolant had drained into the bilge! 

We think it's probably the water pump in the cooling system that needs to be replaced. My husband is planning to order another water pump from Perkins suppliers in the UK and have it shipped to us here in Olbia, Italy. Then he'll attempt to refit it correctly. He's not an engine mechanic and we are a bit worried to ask someone here to do it, knowing that there are very few mechanics working with Perkins motors at all.

So, I am asking for any advice that will help us do the job please. Or if anyone has a mechanic they know in Olbia or nearby in Sardegna ( long shot I know!)

Also, the cover for the place where you add the coolant has just broken! Does anyone know of someone who has replaced their engine but kept parts like this? 

We are so disappointed as we are midway on our trip from France to Greece 😥 any help would be much appreciated.

Cheers,

Re: Running poles

Good to know. I will reinstate the original. I need to wait on that project until  probably when I haul out. In about three weeks time. Drop the poles down below the boat onto a couple of horses…even if I cannot source the rivets I can do the main work, painting and priming etc  and source the rivets at home.

Re: Fresh Water Pump stopped working

It is very easy to mount the one-way valve backward. And, sometimes the on-way valve will get stuck open with a piece of debris. Also, this is very important, any suction leak of any kind will cause the same problem and suction leaks cannot be seen. Make absolutely sure the hose connection to the copper is sealed with silicone sealant. BTW, when new it was glued by Amel.

Or you could replace it with a self-priming, variable pressure, compact Shurflo Aqua-King II! We did this last year. Fabulous pump.

I have the same pump. There is a screw on the left side on the front of the pump (it 13,15 or 17). There you have to add water and then it will start working. That was how I fixed it after replacing some parts.

Re: Fresh Water Pump stopped working

Alex Lomakin
 

Dear all,

A few days ago I dismantled my original SM fresh water pump to clean off lots of rust on a body of electric motor. Did that, gave it a lick of paint, installed it back and it is no longer working: there is no pressure in the system and no water from the taps.
The electric motor spins, the inside of the pump is clean. I also did my best to make sure it was not air-locked, but to no avail.
Any ideas what it might be, please?


Thank you very much,

Alex

Interesting and unexpected observations gentlemen,

This could simply be a little non liniarity or a  bit of offset in the Victron voltage measurement circuits:
you are only talking about 0.28V max. (0.24V is 1% of 24V)

Your good quality multimeter has probably a similar accuracy. Use that to check the voltages as a comparison for more consistent results.

The most important thing is that the individual cell voltage measurement in the internal BMS is very accurate as that switches off the passive/active balancing.

Hoping this is helpfull,

Hi Scott,
Well there you go. I don't understand the mechanism whereby the bottom battery is consistently lower voltage.
Sounds like an interesting conversation with Victron.
Keep us posted on what they say.

Out of interest I just checked my old notes from AGM batteries when I was looking at balancers a few years ago. I had 6 strings, and 4 of them had the TOP battery at higher voltage and 2 had the bottom battery at higher voltage. As I type, my Lead batteries are showing the TOP battery as being higher - see pic.

Re: Chain Counter Sensor Connector A54

Dean Gillies
 

Thanks Vladan, I have sent an email to the Lefkada store.

Roque,
Its not so easy to get my hands on a magnet while cruising in Greece, so I'll cough up for the kit!

The sensor works with a big magnet and I cleaned up both gypsies (grease) and it still works with both gypsies. There is a magnet in both gypsies.

The problem I observe is that it sometimes counts when the gypsy is not turning and the diagnostic test says "unstable sensor output".  My suspicion is still a bad electrical connection (probably ground connection) either at the sensor or at the connector. I think the magnets are ok.

I Investigated a bit further this morning, and found that there must be a connector or joint in the wiring.
The cable coming from the sensor is 3.75mm diameter (see pic), it then runs into a horizontal conduit running to starboard on the roof of the locker. When it exits from that conduit on the starboard side (see other pic), the diameter has changed to 4.25mm.  I suspected that it was different just by eye, and checked it with a gauge.  There must be a joint or connector in that conduit.

So the fault remains the same .. either there is a bad joint inside that conduit or where the wire enters the sensor. 

I will fit a new sensor (glad to hear it pushed out easily!) and I will pull the cable through that first conduit and make the new joint there, discarding the old joint too. I would prefer to make the new joint inside the electrical box on the stbd side, but the cable entry is sealed up so I don't want to disturb it. I'm not sure why Pochon didn't put the joint in there in the first place, maybe the sensor cable is too short.  

On a positive note, after my tugging and fiddling with the sensor cable this morning, the random counts have now stopped. I can spin the gypsy and it counts cleanly, and there is no sign of the random counts.  Definitely a suspect connection! I'm sure the problem will return with morse code-like beeps coming from the cockpit in the wee small hours.

Best regards to all

Dean,

Well it seems there's theory and then there's practice. Or something else is going on.

First measurement after swapping the wiring of each respective serial pair such that the prior "bottom" battery that was previously connected to "negative" battery switch was now made into a "top" battery that is now connected to "positive". And of course vice versa.

For ALL three separate pairs, the new "top" battery exhibits higher voltage than the "bottom" battery at the end of charging. The difference is anywhere from 0.03v to 0.28v. So it was not just a coincidence. 

I may need to have more conversations with Victron about the balancer. If I run the genset in the morning to take my batteries to 100%, the energy balance will remain positive for most of the day, allowing them to work. This should be more than the 4-5 hours that your batteries need to balance out.

Thoughts?

I might be stating the obvious here but unless battery midpoints are interconnected, you will need one balancer per battery pair. They start doing their job when voltage is above 27.3V. For their price, I think they are worth it for any 24V system using 12V battery pairs.

Cheers,
Mike

Scott,
I agree with Dean.  Independent of the band, it makes sense that controlling the total voltage of a battery set in series does not ensure that the voltage of both batteries is sufficient to trigger balancing in both.  The victron balancer does the trick. I spoke about it to a technician of Battle borne and he agreed with its use.  I used to have differences greater than 2% between the  two battery voltages of one set during the final part of charging to 100%.  Since I installed the balancer the differences have been around 0.1 and 0.2%.   I have 4 sets of two 12V 100 ah lithium batteries in series with one balancer.
