I think I said before that I absolutely HATE Volvos. If it is true that it takes some sort of special equipment and something short of an act of God to do a simple compression check, why would anyone,

Jamie, Isolated ground is probably not something that you learned in electrical engineering school, but it is an important thing to understand in a marine environment. Amel uses an isolated ground

Wow, I have never seen that before. Thanks

There's a solenoid (relay) in the positive feed to the starter motor and also one in the negative feed. They both close when the start button is activated and for that brief time the battery negative

No one could do a compression check, since the folks I have to deal with here do not have the Volvo test equipment needed. I would have had to buy it all or bring in some firm from another state. Go

Eric, I guess I don't understand what you mean. How does the negative get disconnected after the generator starts? It would have to be connected in advance to get the starter to even work. Most

Hi Jamie, what a nightmare you have had. We all feel for you. The valve and cylinder damage suspected would certainly affect the compression. Did you ever manage to get someone to do a full

Hi, My generator has an isolated ground and the negative is not connected to the start battery except when the generator is starting. Fair Winds Eric Kimberlite Amel Super Maramu #376

Jamie, Did you actually take the head off the engine and look at the cylinders and valves? Fair Winds Eric Kimberlite Amel Super Maramu #376

Sorry Duane, I only sent you half of the message. Press start and auto together and you should see "wind" appear on the display. The autopilot did not come with this as standard,

Duane, Do you know if you have the wind steering option on Wanderer? Trevor Seafever SM425 Mexico

As I recall there is a button on the autopilot control “WV” for wind vane then it steers a course relative to the wind and has already worked out the angle of the wind and what tack you are on.

Andrew, How do you switch the Autohelm from compass to wind angle control? Duane Wanderer SM#477

Hi Paul We always sail on the wind angel. So it is possible. Den kabeln som har NMEA vinddata kopplas till kontrollenheten i sittbrunnen och inte till kursdatorn. För detaljerad inkopplings

Hi That is one of the first things I did when we bought our boat and wondered why it had not been done as standard but it meant running a twisted pair of wires from the B&G display at the chart

Hello! Is it possible to connect the B&G NMEA out put with the NMEA input on the Autohelm 7000 to have it steer according to wind angle? if not is it anyone who have the Autohelm wind vane? is it a

Jim, I not certain I understand what you mean by "ground-isolated?" The engine frame will be tied to DC earth of course through the battery DC negative feed to the starter, as well as through the

Kent, again thanks for the kind words about my engine failure on Phantom. Just to confirm my comments, I am not suggesting the exhaust design was necessarily at fault, but in my case the layout of the

Jamie, Sorry you're having to deal with this but glad a solution is finally in sight. I don't know if the 54 engine and electrical system is ground-isolated like the SM, but if so, then as others will

Well, I have separated all the 220AC ground wires at the 220 box in the galley and at the 220 boxes in the engine room. I found that the output cable from the generator is grounded to the generator
