ES 50M-65N ATS

[Kenneth Roberts]

No ac power to coach and the ES 50m-65N shoreline controller output voltage reads 0 (115v in). Bypassed the controller by connecting in/out wiring and have power to coach but Aladdin eci module doesn’t recognize and shows leg 1 & 2 as off. Additionally, rc7 indicates 11.2v but Battery voltage is 12.5 per multimeter. Any suggestions appreciated for overnight parts or troubleshooting. Thanks

How did you bypass the Transfer Switch?
Did you remove the cover and physically wire the Shore Power "Input" directly to the "Output" (House) side of the contactor?

If you had the cover off, did you see the current transducer for the Aladdin module? - Just wondering if you bypassed that.

I have a different brand transfer Switch - but here is a photo of what the "current transducer" looks like (one for each AC leg). Does your TS have something similar in it?

Kenneth,
Do you get power if you have the generator running and the shore power disconnected? If so, either bad shore power or the transfer switch. I'd suspect the latter since it does not have surge guard type protection and my assumption is that you verified proper shore ac characteristics. The transfer switch is available from multiple sources on the web by searching for ES 50m-65N. I expect most would provide overnight shipping.
Also, would be very helpful if you provided info on your coach; year, model, engine at a minimum.
Thx, Steve

Thanks for reply. I connected wiring to/from controller using same connectors shown in picture. I don’t see transducer like you pix but will look again. My unit is a 2004 seacliff Monterey with 350 Cummins. I have apparently disable the Aladdin eci module by bypassing the shoreline controller. Not sure if the controller or the memory board is the culprit. The inverter does not recognize that batteries are fully charged

Kenneth,
Are you saying that you have no AC from the inverter either w/no shore or geni ac applied to transfer switch?

There are several "interface modules" used by the Aladdin system to report Coach status on the display. From your post (if I understand you), your Aladdin is not displaying AC voltage or DC voltage.
Did both of these display correctly prior to the problem with your transfer switch?

In the photo below (copied form the Aladdin manual) you can see that there is an ATS (for the Transfer Switch) module and a DC voltage module (for the 12volt stuff). If you are not seeing AC voltage on the Aladdin display it may be due to the way you by-passed the transfer Switch.

But the DC voltage display is a separate module. Note in the photo, on the DC Interface there is a 15A fuse.  Maybe you blew that fuse. Sorry - I don't know where that fuse is located in your Coach. Locate the DC module and test for DC voltage at the plug. If you have voltage, the module is bad. If no voltage you will need to troubleshoot further.
EDIT - I re-read your initial post, and I see now that you are displaying DC voltage - it's just one volt below actual battery voltage. So forget what I said about the fuse.

There is a troubleshooting manual for the Aladdin in the "members only" Coach Assist section of this forum.

There is very little that can go wrong in a transfer switch. If the transfer switch won't switch from shore to gen, its likely that the 'coil' in the TX switch is bad (open). A TX sw coil can be easily replaced.

If the Aladdin is showing 11.2 vdc and the house batteries read 12.7 vdc, suggest you check actual battery voltage at the inverter input. There is a large ANL style fuse between the house battery+ and the inverter. Transfer switch is not in the loop.

Did anything abnormal occur just prior to these problems.

I would like to thank everyone for your comments and insights as it was very helpful. Looks like the shore controller and/or mother board are toast. Have ordered them from esco and will join up with them at next stop in bushnell fl. It looks like the dc interface was ok. Esco was great with customer support. Will post a final report when all is up and running. Again thanks to all 

[Mike Shumack]

at next stop in bushnell fl.

Are you an Escapees member? The Bushnell site has a "smart weigh" service there. I had my Coach weighed and spent the weekend there last year. It's a nice area but no cell phone, TV, or internet access (unless perhaps you have a special antenna or booster or such). I didn't realize how hard it would be to be "unconnected" for two days.

I would again like to thank everyone who replied to my post. Finally was able to replace mother board and shore controller in ats. Power to coach and shore to generator power transferred.  Aladdin displays leg 1 & 2. OFF. Unable to locate the module board with the aci and dci. Compass and tank(s) interface are mounted in the passenger side cargo bay but not the other interfaces. Looked in all other compartments without luck. I have a 2004 Monterey seacliff with 350 Cummins. Any idea on aci and dci location?

In the Coach Assist section, my 2006 Monterey Wiring Diagrams book shows the modules, on or around the 28th page.  Your coach could easily be somewhat different.  The AC and DC Aladdin modules are in the waste tank bay, which if you are not familiar with, is a handleless panel in front of the curbside rear wheels.  It fastens under the drip edge.  The AC module is labeled ATS.  Again, yours may be different.

Addendum:  just noted a 2004 Monterey Wiring Diagram for the Aladdin in Coach Assist.  Just scroll down to “Monterey Wiring Diagrams”, then “2004 Monterey Wiring Diagrams” til you see it under “Aladdin System Wiring”.

[Kenneth Roberts]

I found the aci and dci module in the compartment under bed, so now will try to troubleshoot using the service repair procedure guide.

[Joel Ashley]

Glad you found them, Kenneth.

For others' reference, see the modified image in my last post here, where I added identifying text.

Kenneth,

The attached image has a little more detail for the ACI than is in troubleshooting guide. It is for model-year 2002/2003 but should be similar to yours.

It may or may not be of any help.
