In Topic: Hoses link water pump to accumulator - normal?

Today, 07:13 AM

Hi peeps,

In the ongoing mission that is our boat, I've finally gotten to the stage of replacing dodgy plumbing and wiring buried beneath other jobs. Today, I've serviced the water pump. It is linked to an accumulator, and the accumulator to the system via hoses instead of pipes.

Is there any reason for this (movement?) or could I just replace the dodgy-looking setup with plastic plumbing?

Many thanks!

 

Entirely normal. My last Lloyd's approved boat had no solid water piping at all.

Nick,

 

Interesting, I had been told that the TP was essentially an unregulated 15V alternator delivering to a separate large inverter (in the black box). Your comment seems to debunk that!

 

The similar Dynawatt also employs a ~ 300v alternator feeding a remote inverter. Don't see how it could be so compact otherwise.

In Topic: Adverc/Alternator fault?

I had similar issue with just one of my Leece Neville alternators when weight on the ignition switch key turned it off. Note I also had an external regulator fitted albeit a Sterling one. The pulsing interval on then off was around 20 seconds. Worked fine when ignition was turned back on though.

Nothing new to this similarity surely. Chances are if you want something different it will be less practical/efficient than the norm. Look at back cabins on trad working boats. They all followed the same/similar layout because with over a hundred of years development they offered the absolute best use of small space granted to them as living accomodation.


In Topic: Bowthruster batteries

06 June 2016 - 11:51 PM

Yes you are correct in thinking you have bought the wrong batteries. Your bowthruster motor will be taking more current than a typical starter motor so you definately need starter batteries with a CCA rating. These have a greater number of thinner plates to supply the higher currents needed.

 

Suggest either doubling up with present semi-traction batteries with another pair in series (which will reduce the current draw from each) with power taken diagonally from the bank, or switching to starter/truck batteries. TBH with that size thruster running at 24 volts, you probably need four 12 volt 110 Ah batteries (or equivalent) anyway.

 

Hot terminals suggest a high resistance connection to the cable or inadequate cable cross-section. If you are convinced there isn't a mechanical issue here try doubling up on the cable size. My smaller Nobels thruster uses two 70mm2 cables for both positive and negative feeds as recommended by manufacturer.
