A122 motorized jack story
I have an A122 right around a year old. I swore the battery was going dead, as the jack wasn't working most of the time. This morning I left the campsite and powered the jack while still plugged to 120v. No problem. Got home, lifted the camper off the hitch while hooked to 12v no problem.
Trailer would not then go down. Fuses all fine inside, breakers fine. Power going to LED okay.
Traced the red wire and lo and behold there is an inline fuse assembly that I never noticed. Cracked the twist on open and tons of red rust came out from the spring that is inside. I guess the spring was just loose enough that one end of the automotive fuse had some arcing/corrosion products on it. Roughed it up with some sandpaper and it works like a champ again.
Just posting this in case someone else has similar issues. I didn't even know there was an inline fuse on the jack motor.
