Title: House to frame leveling system
Post by: Mack Turner on July 25, 2022, 11:27:04 PM

I have a 2001 beaver Patriot Concord with the 4 corner hydraulic leveling system from the house to the frame,   Can anyone tell me what activates the LED's nside to show they're retracted?

The SMC Leveling System manual for 2001 Patriots is in Coach Assist.

Thanks Steve I saw the SMC manual and have reviewed it but it doesn't show any kind of information on what  activates the indication LEDs to show their retracted, I'm kind of assuming there's some sort of switch in there that gets bumped but wasn't sure.

Mack,
Figure 6 in the manual seems to indicate there are switches that are normally open when the jacks are all up. Wires 522, 525, 528, and 531 are Full Retract inputs to the ECU which would then drive the All Up LED. The each of the 4 switches will be in the Open position when the associated jack is fully retracted. What the manual doesn't show is the location of the switch but I think it is fairly safe to assume it is on/in the jack assembly. Assuming the wire numbers are on the wires going into the ECU, they should also be on the wires at the jacks.

Thanks again Steve, trying to figure out why my retracted indicators don't light and was hoping there might be an external switch that was accessible,  given your information I may be able to ohm out those inputs. My control panel is different than what's shown with only a On/Off/Retract switch and 4 individual momentary switches to the left of the on/off that are manual extend/retract switches.

Attached to the side of each jack is switch which was originally designed to be a  brake pedal brake light actuator  which is not water proofed. Common problem of water getting inside and freezing up.

Finally got the coach out and was able to look up under it and you are correct it looks like a little switch on the side of the Jack and it's covered in dirt and debris so that's probably why they're not working.

OK it's a standard Coal Hersee momentary switch sold at the auto parts for 26 bucks and marked up a 100% by beaver coach sales if you care to buy from them.
