When I first posted about the breaker location we were in a campground with lots of wind and would have been nice to have the stabilizers working.
After returning home finally took time to troubleshoot on why the Quadra Bigfoot 2 point stabilizers weren't working.
The 80 amp stabilizer breaker is located in the battery box on the right hand side - behind battery. There's also a 60 amp breaker for the converter on the left hand side and both breakers appear to be sealed. After successfully testing for positive voltage on the output of the stabilizer breaker next I tested the switch for positive and it was hot.
Breaker info: Hi Amp Buss 80A CB181F-80
The next step was to raise the rear tires on blocks to gain access to the rear axle area where the two stabilizer jacks and tank assembly are located. Next was to raise a sheet metal cover and exposed the tank assembly.
Surprise-surprise! The first thing I noticed was a couple of loose wires hanging. The bottom red arrow appears to be the ground wire that feeds both retract and extend solenoids that should be attached to the copper strap (other red arrow). I had already read in the Bigfoot manual that there was an extra small ground wire that was not used and that explains the loose wire indicated by the blue arrow.
Ran out of time to make the repair and test it so it will have to wait until tomorrow.
Our Forester was assembled in January 2016 and has about 3500 highway miles on it. (No rough roads) Very disappointed to find that someone forgot to tighten a nut holding a wire that draws up to 80 amps. Plus they left an unused wire with large terminal dangling in a space near significant power cables.
