Yes, I have the Magnum MS2812 and yes, before adding a dedicated sensing wire, I'd see the same voltage drop at the AGS module because Monaco tapped into the battery voltage at the Magnum inverter instead of a dedicated battery sensing wire.

Oh. Sense for the AGS, not for the inverter itself. That makes sense.

i don’t know why Magnum did not provide for a battery sense input from the battery to allow for the voltage drop. I recall asking their tech support if there was one on the inverter, and they said there was not.

The AGS gets the battery voltage from the large 12 volt battery cable connected to the inverter.  To remove the voltage drop on this line, I connected a dedicated battery sensing wire from the house battery bank to the AGS.

Hi Frank,

What inverter let you do that? I have a Magnum MS2812..

I get well over 1V difference between the Inverter voltage and the BMK voltage under high current, like running the microwave.

25 Feet Long!!! OMG!!! What were they thinking or I should say, what were they drinking when they decided to do that.

My battery bay is directly behind the tag axle. My Magnum Inverter is two bays in front of the drive axle just forward of the tank/Aqua-Hot bay.

Hi Richard,

Same as on ours.

Measure it out, allowing the distance to the center of the coach to run forward, and see how close your estimate is to mine.

At least with Lithium, we may have an option to put the batteries in that bay.

Paul

The problem on our 2005 Signature is that the 4/0 cables from the batteries to the inverter are each probably 25 ft long, and there is a significant voltage drop across them. As much as 1.5 volts at high amperage. The voltage the Magnum sees is much lower than a voltmeter or what even the BMK reads at the battery.

Anything the Magnum Inverter is programmed to do based on voltage does not take that voltage drop into account.

What are your symptoms?

Paul

Yep, but may be the best alternative.

Paul 

The IC’s are still available. I expect the regulator is too.

Should be a fairly straightforward return on that board.

paul

Right. I saw the picture of the switches. Perhaps an early 2005 Signature, but not something I have seen before.

@rschley can you confirm your year/model for us? It makes a big difference on the advice we would offer.

PROGRESS.  As suspected....NO INTELLITEC MPX.  That is GOOD. 

That is the first 2005 Signature I have seen without the Intellitec Multiplex.

The Executives and Dynasty’s also got Intellitec from 2006 onwards.

Paul

No issues viewing HEIC images on my iPhone or my Windows 11 laptop.

Have you downloaded any current CODEC’s. This is similar to loading security updates, but for viewing images as new format emerge.

Paul

I am here in 20.

Scotty and Deb Hutto, Van Williams and Pat, Shaun Murphy, Tom and Paula Moore, Ted and Stacey Zimmer.

Hopefully we can catch up!

Paul

Not the same year, but on our 2005 Signature, the air horn valve is on the passenger side of the generator bay.

I am a big fan of the ML-ACR.

We bought our 2005 Signature seven years ago now, and I had to clean the Big Boy to make it work properly. When it failed again two years later, I switched to the ML-ACR, and have not had any issue since 2019.

i did run some wires to the front for the switch, but have since found the Spare Harness that Monaco installed, so it could have been a simpler install.

I have also installed one on our 1994 Signature, and have also helped install them on three other coaches. 
 

Intellitec makes many great products. I do not consider the BigBoy and the associated control board their best work.

Paul

No plans to head as far west as TX, but will be back in New Orleans and up to Chicago in the next couple of months.

Paul

Hi All,

I will be at the Cajun RV Rally April 8-14 if anyone would like their Intellitec system backed up.

There is no charge for this.

Thanks!

Paul

I will be at the Cajun RV Rally.

I am happy to backup any one’s Intellitec system while there.

Paul

Hi Tom,

I sent you a PM.

Paul

Lifeline tech support recommended equalizing their AGM’s to me.

Paul

@Frank McElroy is the best with troubleshooting boards. I am more of a parts swapper.

That relay is not too hard to replace with the right tools, but I would want to see what load that relay controls and consider adding an external relay to reduce the load on the board as well.

 My cruise on/off output went out on mine. That is one of the small black relays. I replaced it and it did not fix the issue, so I wired a fused output around the relay and my cruise is always enabled. Works for me. 😀

Yes it plugs in with a standard plug on one side, on the end you see is apen pin with slip on female connectors. The point of showing it is to resonate with the old phrase… these motorhomes are like snowflakes not two are made the same🤦‍♂️ when i found that plug i had NEVER seen anything like that before. Ya just got to stay open to what if an run with the punches

I found the same plug on a 2005 Signature.

Paul

@Paul J A

Tim does a great job at RVCams, but I don’t think they offer a plug and play replacement for the Velvac Mirror mounted Intec cameras.

Please share a product link if there is one.

Paul

The price is unchanged!

Paul

Camera kits V2.0 are back in stock.

Paul

Hi Richard,

I cut the switch apart so it is just down to the pins, then desolder them one at a time. 

It helps to have a good solder/desolder station.
