Location of the Dash Annunciator


Recommended Posts

While trying to troubleshoot my Faria tach/air gauges (they just started windshield wipering back and forth once I turn the key on) I discovered there are no alarms or notifications for low air pressure, turn signal, light left on, etc. I am not sure if this no alarm issue could be from the gauge issue? I wouldn’t think so since it wouldn’t have anything to do with the other function of the annunciator. I can’t figure out why the gauge is not working any longer but figured I could get new air gauges and use my BlueFire for the RPM’s. If anyone has any idea’s on how to fix these gauges let me know. I know they are not supported by the manufacturer any longer and they don’t have parts. 

 

However, what I would like to find and fix is the Annunciator. I believe its a small box about 2 inches square with a 14 wire plug going into it. I know it should be located in the dash under the access panel but I have taken it along with the gauges and stereo panels out to look and can’t find it. Also looked in the arm rest on the left side of the driver. I’m not sure if it was removed by the previous owner. If so I would think I could find the plug or a bunch of cut wires. So far I haven’t found anything. Any ideas on how to find this? 

 

This is on our new to us 2006 Navigator.

After more searching I don't think I have a dash annunciator. My owners manual says if the air pressure drops below 65psi an alarm will sound. At this point I know I'm supposed to have a low air alarm just don't know how it works, what it looks like or where it comes from.  Can't find any mention of it in the wiring schematics. Does anyone have a 2006 or newer Navigator or Monaco coach and know how it should work? What all items will make your alarm or chime go off? 

 I still have the wiring schematics from my sold 04 navigator on pdf. The first picture is of the 04 nav instrument schematic. If I understand this correctly I would be looking for plug M7 (if I had a 2004 Navigator). My 06 schematics don't show this at all. They skip from plug m5 to m8 all on the same page. I can't find any instrument schematics at all. I'm now wondering if these alarms or charms go thru the actica gauges. 

The second picture is of the back of my gauges. What I believe is the Actia control module? is the black box with 2 air lines goin into it. The air lines are labeled Primary and Secondary. 

Anyone have a pdf copy of 2006 Navigator Schematics? That would be easier to search and I would really like to have a digital copy.  

An one have any ideas? At this point I'm out of ideas and don't know what to do next.

Thanks,

Kevin

Kevin,

I have a 2007 Nav and had one of the air line fittings blow off that annunciator panel.  I contacted the manufacturer and was able to buy a new one and got extra air fittings.  Hope this helps.

Bill,

Yours looks just like mine. I think one of my air fitting were broken at one time also since it's been re-soldered. But doesn't leak now. 

Jim, 

It is interesting to see the difference. Makes me wonder why they add this extra layer of cost and complexity. 

So the piece in Jim's picture is that what controls the alarms and chimes in missing? 

What alarms or chimes do you have? Lights left on? Low air? Turn signal on? If you do have these where does the sound come from? I have a small speaker that the vorad chimes come out of. Do you get all your alarms out of that? 

Also, do you have a low air light on your dash? I guessing I should and wonder if it is part of the text that is on the speedometer. 

Sorry about all the questions. Trying to get a better understanding of how this works. 

Thanks, 

Kevin

For what it is worth, on my 06 Diplomat the annunciator was just above the steering column towards the firewall.  I had to remove the cover from around the steering column to find it. There were several wires going to it.

Thanks for the responses. I have torn my dash apart looking for the annunciator. I'm sure I don't have the typical 2x2 black box that seams to be the typical system. I believe Bill is correct and the missing chimes and alarms are controlled by and come out of the gauges somehow. My speedometer has slots in the back making me think thats where the speaker is located. 

I would really like to be able to repair this and at least get the low air alarm working again but I don't have any idea how it works so don't know what part is the problem. 

I would like to get a manual and or wiring diagram for this system. If anyone has one I'd be happy to pay for a copy.

Back of my gauges. Right one is speedometer with slots (for speaker?) Left big one is the faulty RPM and both air gauges. The rectangle with the 2 air line going into it is the control module? that some have had trouble with. I took it off and it looks fine as far as I can tell. 

Thanks, 

Kevin

Kevin, that looks like an Actia Dash.  Those Orange, Violet, White wires are daisy chained from one gauge to the next.  You can change wires from one to the other as well as changing the gauges they go to & from.  The only requirement is to have them go into one side of a gauge & out of the other side of that gauge and then over to another gauge in any order.  I see someone added a blue Scotch Clip to a wire between the gauges.  If it goes to any of those daisy chained wires that would be a problem.

Jim...thanks for the info. I'll play around with these daisy chained wires and see if if makes any difference. The blue connector is my attempt to verify that I had a good ground to these gauges. It's attached to the ground wire that feeds the gauges.

Also when I had my problem I was able to contact Actia and got help.  

Thanks Bill. thought I had responded back to you after your first suggestion to contact them. I did try to contact Actia with no luck. Left messages and haven't gotten a return call. Do you have an contact info?

I found a note from another Actia windshield wiping and flashing lights problem that was caused by water in the connectors of the Front Run Bay F1 panel Intellitec 73-00835 board.

I have cleaned and checked some connectors in this bay but didn't see anything that looked bad. I am planning on taking all of these board out and clean and inspect since there has been water in this bay. Was actually raining when we went to look at it and was dripping off the ceiling. I believe it was coming from the beltline just above the bay ceiling. I caulked it and believe that fixed it. Maybe I need to move that up on my to do list. 

I had also seen that these may be Faria gauges also. So reached out to them also and did get ahold of a tech there that supplied me with a few documents about these gauges (see attached). Sadly these are not for my gauges but may help someone else. I e mailed the tech to see if he had any info on the Navigator gauges but haven't heard back yet. He repeatedly told me they are not repairable due to parts. 

Appreciate the help and ideas. At this point I have a couple air gauges hooked up so at least I have air pressure reading but sadly no alarm so need to figure out how to get at least a temp alarm hooked up.

This is the info I have which dates back to 2019.  Hope it helps.

Here is the latest update. I took Bills suggestion and called Lisa at Actia and she put me in touch with one of their engineers. He suggested I start by replacing the warning bank (the little square box in my pictures above where the 2 air lines plug in to) since one of the connections had been re-soldered at some point. They still have these available so I ordered one of them and installed it. That did fix my tach/air gauge issue so they are not bouncing back and forth any more. It did not solve my no chime/ alarm issue. He did say I could send in my speedometer and they could most likely be able to repair it. That's where the speaker is located. So I plan to do that this winter.

In the mean time I need to look into some kind of temporary alarm for the low air. Not sure if there is some kind of alarm I could cut one of the air lines and install with a T? Something that would give me notice that I'm loosing air pressure.

He also sent me the attached manual of the gauges. Would have saved me a lot of work and time if I would have had this earlier. Hopefully it will help someone else.
