Over the last couple of months my Ulterra was becoming more sluggish when deploying or stowing. Once it deployed, it ran fine. Saturday it died. When I press the deploy button, it would move about an inch and freeze. Red status light would blink. Batteries are 2 12v 100ah lithium bought 14 months ago. My first guess is the trim motor has gone bad. Anything else I can check before taking it in for service?

have you seen this video, watch till the end

ulterra wont deploy

I watched that one last night. It is on my check off list.

Did that fix it?

Here's a fix with pictures instead of video and it's for dummies lol. Used it myself in the past.

Heh, mine just powers off when I try to deploy it. Both lights are steady on. I double tap the remote button, and the motor powers down.
