Re: [Amel] Isolated or non Isolated DC to DC Convertor

Mark Erdos
 

I think if you do not understand the need for an isolated DC-DC convertor for the SSB on an Amel, you should have a qualified electrician do your installation.

Correct.

 

And if you look at the circuit diagrams provided in the manual you will see that for the low power 24-12 VDC converter installed by Amel, the -ve of the 12v supply is connected to the -ve of the 24v supply...ie not isolated.

This is assuming (rightly or wrongly I don't know) that the GROUND of both the SSB and the Tuner are connected to the negative power rail.

 

Another thing to think about: if you had a 12volt system of the same design and you fitted an SSB you wouldn't need a DC-DC converter and you would be in exactly the same situation as using a non-isolated DC-DC converter...ie the negative rail on the SSB would be connected directly to the negative battery connection.

 

I had this setup in my last boat (steel keel and skeg) for 14 years and never had any corrosion problems.

 

I don't believe an isolated 24-12 DC converter is necessary.

Most boats have all the dc negative, and bonding connected. Amels do not.

The Dynaplates and copper bonding that is connected to the tuner and the SSB are not connected to the bonding of the boat. Amel is unique in this respect.

I would start by using corrosion x on the start switch, stop switch ( without the cover) and all the other possible  suspects including the stop solenoid.

Thanks Eric. I agree. That stop solenoid is integral to the injector pump and would be a bear to change.  I think the solenoid operates a valve of some kind that is open (allows fuel to flow) when the solenoid is not energized, and shuts fuel flow off when energized.  There is a relay on the aft end of the engine that appears to energize the solenoid.  I'm thinking that relay may be fused in the open position.  Still not sure why the engine cranks and fires when the switch is in the START position.  At least I could run the engine if I had to by disconnecting the stop solenoid, and shut it down manually.  I'll let you know when I get it figured out.

The fuel is okay. The engine cranks right up when the key switch is on "Start" but as soon as the key is released to "ON" it shuts off.  I think it's a problem with the stop solenoid that is bypassed when the key switch is at START. If I disconnect the stop solenoid, it runs fine..

Hi again,

I started my Yanmar 4JH4-HTE 110 HP after ~2 months of sitting unused.  It cranked up in about 1 second and purred like a kitten for about 5 minutes while I was getting ready to shove off, then died abruptly.  First thought was forgot to open the fuel valve, but it was open.  When I try to crank it now,  it starts up immediately, and respondes to the throttle in neutral as long as the starter is engaged, but as soon as I release the key back to "ON", it dies.  I've checked and there doesn't seem to be any air in the fuel lines, and the pump on the fuel filter feels normal.  The generator runs fine so I don't think there's a problem from the tank to the Racors.

 

I'm thinking that the fuel shutoff solenoid may be open when the switch is in the "START" position, but closes when the switch goes to the ON position.  I guess there are any number of automatic shutoffs that can occur if a sensor fails (like overheating, ??? else).

 

When I manually close the fuel off (like you would to manually shut down the engine) and crank, it's obvious that there is no fuel getting to the engine.  When I crank it without shutting of the fuel manually, I can hear the engine firing, and if I advance the throttle it runs faster as long as the key is in the START position.

Re: [Amel] Isolated or non Isolated DC to DC Convertor

There is no Neutral on the Amel shore power.

The engine and Generator have a floating ground. In other words the motors are only connected to the boat ground when they are starting.


All the other gear on the Amel is connected together with a green and yellow wire which is connected to ithe rudder stock and the two zincs on the ruder. The amel does not conform to AYC standards for a number of good reasons.

Re: [Amel] Yanmar Starting Problem

David Pawley
 

Check your fuel filter, sounds like you may have a eco system in there that blocked your filter. To check shutdown solenoid S/D, get someone else to start/shutdown while you look at the S/D stroke, also look at connections. In the absence of Engine manufacture instruction, think the shutdown has as many as 3 transducers that could effect S/D, also there is time delay to allow oil pressure to rise, Temperature probe faulty, push button stop, Maybe something else.
 Let us know how you go.
