Lost power to Engine hatch, Bilge pump,Galley pump and Engine room blower

RinkerNorway

Hi.  

Just sudden the above stopped working at the same time.
I have checked the fuses under steering helm (i guess these pop out if they have some problems?)
Also checked the power breaker at the DC panel. The one for "Helm power" is working, as by tuning this on/off the other functions on the switchboard is affected.

Anyone with any ideas?  Seems strange to me that all these 4 things went out at the same time.

Have you looked in battery switch box? There are pop out breakers there too.

RinkerNorway

Hi. Yes. with DC panel, I was referring to the panel where the larger power breakers  and battery switch is located.  All pop out breakers there are good.

Sounds like items that would run off the "house battery" you may want to use a jump box to provide power to the engine hatch and check the battery treminals.

So my brand new house battery lost a cell a few days ago, and I was surprised the house battery runs the blower and genny starter. I would've assumed that would run off the engine battery, so if you drained the battery down overnight, you could still safely start your boat (or at least the genny to charge batteries back up).

I'm going to have to document where everything goes now, as it doesn't match the electrical sources supplied by the manufacturer. Crap.

@RinkerNorway, I'm not sure if you are aware but you can put power to the two terminals in the switch box to power engine hatch. the picture below, where the two red twist caps are the two thermals. I know this does not fix your problem but at least you will be able to open hatch to investigate.

Hi guys.

i have already checked everything in the engine room without any findings...  all 3 batteries are at 12.5V so should not be battery related, since every other electical installation is working perfect.  

Could some of the electric components just be hooked up to one of the house batteries, and the rest to the other battery? I thought "everything" was working together with both batteries (?) 

Appreciate all your help.

If I remember correctly all 4 of the items are on separate breakers, under the steering wheel.  I think I would take that panel lose so you can get to the wires that power's the breakers. test for power.  What boat do you have?

@RinkerNorway, what boat do you have?

RinkerNorway

Sorry for that. i have a 2007 Rinker 280EC running on tractor fuel(Diesel)

oh boy, not sure Handy will be able to keep his excitement down!

Ian

He may take exception to the agricultural reference though.

randy56

Handy will be revved up.

All 4 run off of the house battery. One thing I found with my 280EC is that the connection at the breaker was loose. It wasn't making good contact, so my house battery wasn't getting charged the way it should. I had to pull out the DC panel and tighten the connections. While I was there, I changed the breakers for the house battery and the starting battery. Here is a link to the wiring diagrams for our boat. They are in PDF form, so feel free to download them. I have used them a few times, so they are great to have.

Dude_Himself

Double check those wiring diagrams - mine isn't that accurate for which battery powers which circuit. Not sure if it's cause I have an early 280EC run (2007), or if things were changed up by a previous owner.

So..

Season is nearing, and I need to sort this problem.

I have removed the main breaker panel and all looks good, even loosened every connector and re-tightened it to ensure good connection.

since me+Wire diagrams are complete enemies, it has not shed any light on where the problem is located.

Can anyone check what the main breaker labeled "Steering Helm" actually does? I have tripped it to see what stops working, but other than the things mentioned earlier, everything is working despite that breaker is tripped/unconnected.

You really need someone who can use a volt meter and I am sure you have a Yanmar diesel??

RinkerNorway

Volvo Penta D4-260

I have a Volt Meter.

there is Power to both the button/switch for eng hatch along with the small breaker for hatch under the steering helm.

so seems like it's a bad connection between the breaker at the helm and the actual hatch motor.

same goes for the Blower switch and water pump.

I have also checked grounds at the aft "wall" in engine bay, all are good. Is there any other places where stuff are grounded? (already taken out the landpower/fuse cabinet inside the boat, all looks good...

RinkerNorway

Acoording to the wire diagram, this has gotta be where my problem is located. 

Any idea where to find this connector/connection (connector 10) point?

RinkerNorway

Located the problem.

connector in the middle of the picture had come apart just enough that it had no connection.

All is working

Nothing better than an easy and free fix!!!!

Maybe put a tie wrap around it to prevent it from happening again if the clip is broken.

ivy282

I have sort of same issue, what location was that connector found in? I have a 282 have power to switch and circuit breaker. When I hit button to open power drops out. Like I have a bad ground?

TonyG13

Having a similar issue as this old post.

While underway yesterday lost power to Raymarine multifunction display  (chart/radar), nav lights, vhf, horn, arch lights, floor lights, transom light. Also no power to main blower or engine hatch.

Batteries are new this year. VV display still works as do all engine functions (Axius, etc.). Checked every available breaker - nothing unusual found.

I have a feeling it's a multi-pin connector that may be loose somewhere?

Anyone have a 2014 310 EC diagram to see if all these route through same bundle/connector? Or where to look to troubleshoot some more?

YYZRC

I think you're right about a multi pin coming undone. When you find it, wrap a zip tie around it after securing!

LaRea

Look for a connector on the backside of the battery switch panel.  Should be a connector that sends all of those circuits up to the helm.  

The VV is powered by the DTS circuit, so it would not be affected.  

TonyG13

@LaRea - Are you talking about this panel? Unscrew and check the connectors?

LaRea

Yes, I think that's the only place where you'd find wiring that affects the helm AND the blowers/engine hatch.  

Of course, yours is wired totally different from mine, so I might be off-target here.

jandav

I had a similar problem on my 280EC -2007. The Engine hatch stoped working and the problem was the connector the sits close to the hatch.
