HappiJac Issue

I am having an issue with my HappiJac system in my 2012 Voltage Toy Hauler V3200. During our last trip, the beds worked fine to come down. When we got ready to leave the bottom bunk would go almost half way and then stop. It doesn't look like it is hitting anything and worked fine before.

After we got home, I have tested the upper limit switch and tried to turn off the brake to see if I can manually move the bed up. My brake only has a on/off, and it seems like when it is in the off position, I can't manually move the bed up.

Any Ideas?

Thanks ATCguy. I have read through that and tested the limit switches. It seems like the brake is not letting it go up, but I can't seem to release the brake.

Just verifying... did you also unplug the motor?

(from page 9 & 10)
To Manually Raise the beds:

Note: Before manually cranking the bed-lift, the brake must be released and the motor unplugged.

Use 1⁄2” hex socket wrench. Cranking is easier if 2 people crank, one on each side of the coach.
1. Unplug the motor
2. Release the brake
3. Turn hex shaft using a 1⁄2” ratchet wrench. 4. Re-apply brake at desired bed height.
5. Reconnect motor plug.

Sorry for the delay, we were off-grid using the trailer.

I did figure out part of the issue. The brake on our system has to be pulled out of the divot and moved up. My son was looking at it and moving it to the off position, but didn't realize that the lever had to be pulled out of the divot to be released. This allowed the brake to be released.

The bunk still won't raise all of the way, so I am going to call HappiJac to see if they can figure out why.

Lower it down all the way and inspect the chain in the channels to see if there is anything in them catching on the gear as you go up.

Also check the mounting screws that hold the brackets to the wall, mine were half way out and some were also stripped, the lift arms could be catching one of the screws if it is partially out
