Wiring Diagram
 

Hi,

Just like Nickc, I am looking for a wiring Diagram. I am about to wire in a VHF into my new SX18 - arrived on Sunday - but need a wiring diagram.

Anyone got one they could email?

Thanks

P.S. About to post photos! :yes_grin:

DO post the pictures... lots of them
 

:yes_grin:

I am awaiting my new SX18, it is due beginning of April, a bunch of them will be shipped to the Netherlands where I can pick mine up at the dealer and drive 300kms home to Belgium. Can't wait to have it.

Very curious to see some pics from other angles / details than those from the brochure (which I know by heart already )

Cheers,

Johan

Whatever angle you want I have it, i took over 100 photos of mine before it arrived!

I have video, new one with my VHF (Navman 7200) dashboard mounted, Garmin GPS 550s about to be fitted.

I will put some on the gallery, but other email me for.

I already have a fair amount of electronic manuals, and info on the annoying bilge pump!

:wink_thumbup:

Hi Dave,

what exactly is annoying regarding the bilge pump, does it need modification to perform better ? I certainly am interested in that info, you made me curious ;-) Thanks again for the pictures, at least I had something else to look at than just the brochures the last couple of days.

Friday I picked up the paperwork for the new trailer ( so that I can request a license plate, here in Belgium if a trailer is > 750kg it needs it own license plate). Coming friday I can pick up the actual trailer and let's hope by that time she (SX18) has arrived at the dealer as well...

Cheers,

Johan

The Bilge pump is automatic and cannot be turned off!:shakehead:

By this I mean, that it decides every 3 mins or so to turn itself on and runs for about 1.5 seconds, looking for water. If it does not find it, it turns itself back off. It repeats this non stop. This feature cannot be stopped, even after turning the main battery switch off.

I am sure the thinking behind it goes to where the boat is stored. If the boat is in a Marina, and you leave it there for a week or so, you might want to turn the battery off, but at the same time you want to be sure your boat is not going to fill up and sink.

On the other hand, my boat is stored in the garage, and there is no chance of it filling up and sinking !

So all that happens is the pump keeps running, slowly flattening the battery.....

OK at home I can hook up a battery charger... but during the summer, the boat is stored in a barn near the sea.... no power :punch_out:

So I have to find a way de-activate the pump when not in use - hence the need for a wiring diagram.

The wires to the pump I can just about see... but there are 3 wires...

So now you know

Dave

Thanks Dave, now I understand, that is indeed a pain...

3 wires ? I don't dare to think the other one is to make the motor of the pump turn in the other sense (filling the boat instead of pumping water out of it)... but that would be quite silly !

Kind regards,

Johan

Check out the pics of my boat and XRst's as well in the Gallery, heaps of photos from various angles and all in use by owners.
I am sure you will love your new Mariah as much as we do.
And dont forget to post lots of pics from your beautiful part of the world.
Mayal had the same problem with his bilge pump, I will send him a PM and see what he has done about it.
Check out what he had to say under "General Chat - Introductions - New Mariah"
Sorry dont know how to put a link to that page for you.
Good Luck, if you manage to figure it out before hand, let us all know.
Tony

Mayals home computer is down, and he cant access this site from work - he asked to pass this on to you about your bilge pump.
He had the exact same thing happening to him, so he contacted the dealer, who said to him that the bilge pump will come on every couple of minutes looking for water, if it finds none it turns itself off. The dealer said it would take a year of doing this to drain the battery (obviously draws very few amps).
If you use your boat often enough (at least once a month) I cant see the battery draining personally, but over an extended period I would have to think that it certainly would have an effect on your starting the boat. I will be disconnecting my battery when winter comes anyway.
Hope this helps.
Cheers
Tony

Hi Tony,

Thanks for your help.

No mater what they think, the pump drains the battery quick. Think about it... when left running in its automatic mode, the pump runs for 6 hours every month... but this is not a constant 6 hours which uses less power, during this time the pump will have started and stopped 14,400 times!!! :eek_animated:

Eventually I have had a reply from Mariah. They kindly sent me a part harness diagram. ( I will post this in the manuals section) They also reccomended putting a switch in-line with the Bilge pump fuse.

I feel a project comming on, so look out for the post in the projects section.

Dave

Gotta wonder why they had this stupid feature in the first place :shakehead:
If your boat is moored constantly it may help, should be a option really.
I will email Mayal and pass your info on, so thanks and I will tell him about the wiring harness info - wouldnt mind getting my hands on it too.
Thanks
Tony

Aha! more info.....
 

Finally I decided to just get in there and find out how to silence that battery sapping bilge pump!

First I lifted the dashboard to expose the circuit breaker. - see photo - I disconnected the spade connectors from the circuit breaker only to find the pump still kept running :mad: It seems the circuit breaker next to the bilge pump is only for the switch and not the auto function.... - keep hunting.

Then I investigated the inline fuse on the battery switch (right hand side) . - see photo - Removing the 5A Fuse on the Battery side of the switch did the trick :wink_thumbup:

This stopped the auto pump running, BUT the switch on the dashboard would still work for manual operation.

However, as I do not want to take the fuse in and out all the time, I will have to fit an inline switch - but for now at least it is quite :)

Dave

Awesome work Dave, I will pass this on to the other guys with the newer Mariahs.
Thanks for all your work and sharing with us. :wink_thumbup: Top stuff.

What it looks like here is Sea Fox - Mariah installed a cheapy bilge pump not equipped with a float switch. Rather than remove the fuse or install a toggle switch you have to worry about, i would install a float switch next to the bilge and use the circuit that the 5 amp fuse you removed was protecting. This way you still retain the automatic feature incase water does come in the bilge and don't have to worry about flipping a switch; it's completely automatic with no "searching" for water by coming on every 5 minutes.

Here's an example of the switch i'm talking about:

http://www.westmarine.com/webapp/wcs...5&classNum=304

Funnily enough... the float pump you listed is made by Rule... the same company that supplies the pain in the a** drain your battery pump. Rule advertise it as better than a float switch and it is advertised on the same website at nearly twice the price of the float switch.. but I would much rather have the float switch model!

The problem with fitting it is that the current pump is exactly dead centre under the engine... absolutely impossible to reach...:mad:

So I guess it will have to be a switch, bearing in mind that the dashboard always works... fuse or no fuse

Dave

I asked the guys at SeaFox about this Bilge Pump system. Here is the reply and attached PDF's for the pumps.
If you have any queries regarding the newer Mariahs, Stewart has always been very helpful. Just send him an email, I am sure he will help you out.


Attached you will find the information you are looking for on our bilge pumps. Overall, I would say our response to the pump has been very positive. We made the change about two years ago because we noticed a lot of warranty claims for the replacement of float switches and bilge pumps. Our engineering department found that debris was clogging the float switch and shorting the switch and pumps. Since the change, the claims have been dramatically decreased and we have found the once boat owner's understand how the pump works, they are generally pleased. If the boat will be taken out of the water for an extended period of time you may want to consider removing the in-line fuse from the pump.

Please let me know if I can be of further assistance.

Hi Dudders,

I have spoken to Stuart a couple of times... and he also sent me the same information which I had placed into the owners manual section. he also posted me an addtional leaflet that explains the 3 minute run on time. Additionally he sent me a wiring diagram... that was not much use, but I will add it to the manual section.

What frustrates me is that the clear priority is to boats in a marina. If you boat is out of the water when not in use, the remove the fuse option is a real pain. It is awkward to reach, difficult to remove, easy to drop AND very easy to forget to put back in. The switch on the dashboard is a rocker - the backside of the rocker is not used, so maybe that would be a better solution. Failing this an illuminated inline switch by the fuse would have been an easier solution.

I am sure their warranty claims maybe down, but my battery charge status is also down - not much good when the boat is stored where there is no nearby power.

Ah, didnt realise that you had already sorted this and posted it. Sorry for doubling up on the info, teach me for not reading the forum eh??
I agree, it is a real pain, and yes directly focused on moored boats, there really must be a better option. I bet Jimmy Faulks wouldnt have let this go as it is....

Re: Wiring Diagram
 

Couldn't help but reply to this one. Not sure of the model battery switch Sea Fox is using, but it is a matter of which terminal the power for "auto" is attached to. A typical Perko 2 battery switch would have a 1 2 and all, i believe (common, maybe, been awhile). Switching the ring terminal from the "battery" terminal to a "common" would kill power to the auto side when the battery switch is turned off. Understand, however, that the automatic feature of a bilge pump must be active from a manufacturer, due to obvious liability. RV manufacturers have faced the same dilema with voltage draw from 12 v CO Detectors (Was told they cycle every 90 sec. at a miniscule amperage). Anyway, somewhere in the fine print is where they will tell you that they are not responsible for water ingress due to a modification of the automatic system. Just my 2 cents.
