Not sure if this has been answered...I suspect you have already answered this for yourself, but yes, turn both chargers on.

Some additional insight on your use of the adapter. I know you also have a 120V 15A outlet you were thinking you could use. It would be possible with a couple of adapters. A 50A female to 2x30A male Y adapter and a 30A female to 15A male would do it. This would give you 30A and 15A into the two sides of the Y that combine into the 50A inlet. I guess you could even end-up with 240V if the 30A and 15A receptacles are on different sides of the bus in the power panel, but your 240V amperage would be limited by the 15A circuit.

In terms of consumption, I have 2x30A shore power cords and used to use a Y adapter to plug into a single 30A outlet. I rarely tripped the breaker in the panel, but did on occasion. This would mainly happen at breakfast! The thruster charger, both air conditioners would usually be ok (typical when we returned from anchor), but add-in anything else and that would go over 30A. The air conditioners have high inrush current when the compressors kick on.

The hot water heater would sometimes put us over the top as well. This was typical when we did dishes after getting back to our slip and were cleaning-up to head home. The practice was to turn off the thruster charger until we were leaving and turned off the air conditioners. It wasn't ideal, but workable.

I will start with the single 30 amp (dock) to 50 amp (boat) adaptor first. The new power pedestal with 50 amp will hopefully be installed in 2 to 3 months. The wait for City and Coastal permits is painfully long these days. If there is a delay, I will add the Y adapter.

The Pronautic 24/30 is for your thruster batteries. The 24 means 24 volt and 30amp. The other charger is for your mains. I had the Intelli-Power unit and never an issue. Conditioning would mean your batteries are fully charged.

That's reassuring. Thank you!

The ProNautic Charger is the best! Change out the Intelli-power to the ProNautic. The "fuses" you showed are "fusible links". You will have two since you have a bow and stern thruster. They are cheap, like $19 each. Carry a few on board. Be careful laying over the engines when you change them it it is hot. When you get sweaty, you will ground yourself on the engine and get a tingle.

You have found the reason your thrusters do not work. Well done!

Thanks for the tips, Jay! I will be careful with changing the fuses. I didn't think $19 per fuse was cheap but that's the reality of boat ownership.

Ok, let me take a crack at this! EDIT: I see my long / slow reply repeats what a lot of others have already said...sorry about that!



I would say the left one is likely for the stern thruster. Are there just two of these in total? Does one go to one solenoid and the other to the other solenoid (I assume there are two solenoids...I can't remember)? There is a fuse from the charger somewhere as well, but it should only be 30A.

Unfortunately the drawings available don't show the option with a stern thruster, so I don't know how it's wired. If you look at the what is available for a bow thruster config, the power for the rocker switch, and the indicator lamp on it, comes from that power source.

View attachment 103310

The yellow show the 200A fuse, the line side of the solenoid (top), the load side of the solenoid (bottom) that is connected when the solenoid is energized, and the indicator lamp. Perhaps with a stern thruster, the rocker indicator is wired in an "AND" manner. If there is only one solenoid for both thrusters, then this diagram shows the switching correctly. Not sure where in the circuit the stern fuse would be...maybe on the load side?



You can call me Brian! Conditioning is a charge mode that the charger enters periodically when the batteries are fully charged to desulfate the batteries. It looks like charging is working properly and they are fully charged.



That charger charges all the other batteries (house / starter). The other charger breaker on the panel in the salon turns it on.

Hopefully this helps!

Hi Brain,
Thank you for the schematics and the explanation. I hope changing the fuse will solve all the problems with the thruster. Do you know what could have caused the fuse to be blown. During the sea trial, the captain only use the thruster for a few seconds. The second captain who did the delivery and training used the stern thruster quite a bit longer and more often. Could that be the reason?

Can someone tell me how to get the cockpit lights apart? The ones under the bridge overhang. I want to replace bulbs with LED’s, and don’t want to force and break. I’ve got all the salon and galley changed over. And while we’re on that topic, anyone know what size LED bulb would be needed?
thanks

Actually had mine apart Sunday and ordered the red blue white LEDS from marine beam. the flat disk type. using the same type all thru the cabin also, cool white flat disk type.
the chrome trim ring rotates and comes off. the lense has a slot that i stuck a butter knife in and it came right out. I also removed the screws (3) of them. that is unnecessary to remove the bulbs.
changing out the bildge lights also. using the LEDs there also from marine beam. all these bulbs are not cheap but is a great upgrade. I plan on doing every light on the boat in the next 2-3 weeks.

Thanks for the info. Were are you putting the 1156 base bulbs? I also want to change the lights in the arch which I think are perk's like one used for stern light so I assume those are also festoons.
 
While I'm thinking about bulbs and lights, can someone tell me the size bulb that goes into anchor light, so I can just order an LED replacement and only go up to arch one time?
Thanks.

They are all actually 1141s. Those will go in the bilge and where the washer and dryer’s he is.It will make it super bright

Not sure. The controller has built-in protection that prevents changing direction too quickly (I think there is a second or so delay) and also extended use...two minutes I think I read. I also think I read the delay can be disabled. If it is disabled, or your controller doesn't have it, and the captain was going back and forth with it, I suppose it could blow the fuse.

where did you find the anchor led bulb?
Click to expand...
looking at marine beam's website. I still want to verify before ordering if it has one or two bulbs but I think it's two. Need to go turn on nav lights and see if only one side lights up.
 
The anchor light will be 360 degrees, seen from any direction.

I checked and there are two bulbs. Both come on when you select anchor for that 360 visibility, and only the front one comes on when you select running. That's in addition to the stern light when you select running. Of course the rear bulb of the anchor light blew out when I was messing with it today, so I just ordered a bunch of replacement bulbs from marine beam.

What is the sku number from marine beam?
 
I changed all the interior bulbs today. I used Yuiip no flicker led, 1.2 watt 2700k pack of 10 was $16 amazon. I think it was Carpe Diem who recommended them
