Generator not powering cabin equipment.

Is your genset actually putting any power out?

Being a genset I would say that typically it will provide AC (Alternating Current) to a switchboard of some sort, this switchboard will also probably have another supply that comes via the shore power cable.

There will be things that are powered by shore power that are powered by generator when the genset is the power source.

Does this electric meter read voltage when you are using the shore power and the genset when everything is working as it should?

If this is the case and it reads nought now I would tend to believe that the genset is not producing anything.

This could be as simple as a breaker that has tripped somewhere, a tripped fuse in a control circuit etc

You should have a double breaker on your panel with a slide cover over one of the breakers. Once you start the gen throw the main a/c breaker off, slide the cover over to cover it and throw the now visible breaker on.

I don't know if this will help or not, but on the 53 carver I run, there is a dial that you select which power source gets displayed. It has forward/rear shore power/ generator. However, you still have to turn off the main shore power breaker, and switch the generator breaker on. Then you can see the generator power. Just a thought.

I don't want to complicate this thread, but I have a relay in my panel that will automatically switch between shore power and inverter.
The inverter will not power the panel when the shore power is hot.
When I disconnect the shore power or turn off the power to the cord the Inverter kicks on.

On a lot of Azimuts, the shorepower plug has to have no power coming in, in order to transfer to generator power. Try starting the generator, then switching the shorepower breaker off on the dock, then switching over to generator power. If this still doesn't work, Azimut likes to use DC solenoids for the power switching and the solenoid may have gone bad. They could be located anywhere, but are usually behind the panel on the aft deck where you switch power.

If DC is required to run any part of it the DC Source ( Batteries) might be flat or defective.

This old practice has stopped vessels from very high pedigree yards in the past.

Yes, I've had it happen on an Azimut where the batteries went dead except the generator bank and with the generator running, couldn't transfer power to generator in order to get the battery charger going. We had to put a portable battery charger on an extension cord on the bank just to get enough juice for the solenoid to operate. I know for a fact, the power switching solenoids are DC powered on Azimuts at least 80' and under.

Azimut also uses some safety mechanism where if shorepower is present it will not allow you to transfer over to generator power. Unplug the shorepower and then it will transfer, which is what is going on in the OP's situation.

I've done it many times in tighter engine rooms. When it happens I know exactly what to look for though. You learn as you go.

Glad to hear it was an easy and cheap fix. Have a safe and fun summer.

I am having the same problem with a Sea Ray 330EC with a 5KW Westerbeke generator. Genset runs fine. No power at the MDP. Generator was hust rebuilt and reinstalled. There is a pushbutton style breaker on it but it is not tripped. There is no breaker switch. There is what appears to be a screw in fuse on the generator. Does that fuse the output or the run circuit of the generator?

Call the people that just rebuilt it, they should ensure that the generator runs and produces power if it was just rebuilt.
