Fred, I’m pretty certain that it’s a tubular (horizontal) motor, from the online documents and the two awning ends looking like twins (no vertical bulge on the left end cap).
I did get the cabinet panel down, and discovered Steve was correct when he mentioned a controller. Though not in my wiring Beaver diagram book or the online discontinued product Carefree diagrams, it’s there... double-sided taped to the back wall just above what appears to be a main awning controller module. Of course with a Magnum inverter remote, Kingdome satellite control, two sets of awning controls, the Aladdin reset, and front slideouts switches up there, the area is a snake pit of wiring. That’s always fun... trying to support the loosened panel without straining any wire while tracing and checking individual wires and connections of various styles.
After perusing the situation a bit, I elected to put this project on hold until I had more time. The reason is twofold.
One, the on/off switch with a key has voltage going to the next in line rocker switch, regardless of whether the key is turned to ON or OFF. This is me scratching head full of electrical ignorance 🥴.
Two, the blue wire from the rocker switch to the controller connects in a port labeled “MPX” BUS; so I check the Multiplex modules and fuses in the bathroom cabinet, and all seems okay. But pulling the 10amp minifuse (#8) marked for awning, thermostats, sat power, and TV booster does not shut off any of those things. This is my multiplex ignorant head scratched into oblivion 🤯.
So anyway, I will have to sort this out when time permits. Perhaps I’ve misinterpreted the MPX mark on the controller port. Regardless, it has 12v power there. I assume the controller is intended to behave like a relay and put higher amp power to the awning motor. I’ll need to check that function. I did note by touching the meter to a nearby door jamb bolt head that the obvious ground wires all do have continuity to chassis ground . If need be, I may remove the controller, disassemble it, and look for blown capacitors or some other obvious circuit board malady. That proving okay, I reckon I’ll have little option but to try getting the left end cover and plate off and replace what’s probably a failed motor.
