Bavaria Yacht Help! / Re: starter battery charging to 15volts
« Last post by marioxp on March 17 2024, 12:39 »
measure the voltage between the sensing wire and the alternator housing (or from where it gets the negative pole) to determine what battery voltage the alternator sees.  And compare it to the battery voltage.  Either the alternator sees a lower battery voltage and therefore charges it with a high voltage, or the regulator on the alternator is faulty.

this time is it was charging both the starter battery & house bank to 15.5 volts,
Check your alternator regulator.....

Bavaria Yacht Help! / Drilling holes to the frame of the floor
« Last post by elias on March 16 2024, 16:51 »
Hi ,
I want to put an extra flexible tank under the floor panels and connect it with the kitchen sink for a tap . So you think is a good idea to drill where I have marked in the picture ? Did anyone have a similar idea or application?

Try this ,instead the sensing wire connected to the house battery , connect it to the starter battery

That's not a good idea; the house batteries will get less charge.
You are right but if it works he can go out for a sail with less stress .

Most likely a poorly connected sensing wire, as I suggested earlier.  Re-making all the connections will have sorted it.

Back in the past similar problem solved this way .

Hi All
I hope you are all well.
Still having issues with my charging set up.
Here,s an update.

Original fault
Current set up suddenly started to charge the starter batter to 15.1 - 15.2 - then 15.3 volts then triggers helm tacho with battery alarm.
The house bank at 420amp was fine charging to 14.5 v no problems

Changed the alternator on advice from my engineer still same
Changed the starter battery for a new one old one as measured 62% state of condition still the same
Checked again with my engineer all connections disconnected cleaned and reconnected fault became intermitant.
Changed out the diode splitter as reccomended on here for a Victron argofet splitter

Now come to the boat after a couple of weeks of it charging to 14.5 volts & holding as it should thought we had cracked the fault.

Just tried it now to go out for a motor and at 100% battery charged on both the house bank and stater battery before starting engine.

Charged to 14.8 then 14.9 all the way up to 15.5 volts which I have not seem before what was odd this time is it was charging both the starter battery & house bank to 15.5 volts,  not seen that before this fault was only on the starter battery side hence here some suggestion that it maybe the original fit diode spliter that was at fault.

To be honest I am lossing the will to live with this last time at the boat I could have drilled a hole in the bottom & gone for a coffee!
Its been going on since August 23 & have not been able to trust the engine to go out.

I really don.t know enough about electrics to move forward can anyone suggest anything that will help something else to check ?
My engineer is very busy and sometimes takes a few weeks to get to the boat to have a look see but when he,s onboard it works normally and tops out at 14.5 volts everytime he,s here I have filmed it on my phone just so he thinks I!m not going bonkers

Thanks
John

We use the 603 for Quicksilver 320 AIR DECK and it is totally ok.

3 bar seems a high pressure for the pump system to run at, sure flow pumps I've seen are around 20/30 psi that's around 1.5 to 2 bar, i would assume running at higher pressure would cause vibration in the pipework when it pumps up to high pressure as the pump is working harder, the other bit that might cause it would be if the accumulator diaphragm was split, so there would be no cushioning effect for the pulses from the pump.

The factory-fitted original pump was 3bar.  It's a Whale Watermaster and no accumulator is needed.
