Trim tab not going up.
My starboard trim tab is not going up. It is full download and I only get a click when I try to retract it. Motor runs if I push the down switch. Port Tab works fine. Tabs are Dana 1000.
Must be my time for electrical gremlins.
help,

Most 'un-scientific' but.......
Different tab, K-plane 380 was stuck all the way down on my old boat, had someone stand behind and with all his force, pull the tab up as I hit the switch. He suggested it was stuck at a point it had never been before (I didn't believe they go down so far!) and a solenoid or relay was cutting out when the pump couldn't shift it.
Dont know if that makes sense or even if the situation is similar but it worked for me.

the dana 1000 is essentially a k-plane. uses a merc trim pump for each tab. so you have 2 solenoids mounted on each tab motor. have somebody do tab up and down while you are touching the solenoids. you will feel 1 click and motor will run 1 way. other clicks and no motor noise. jump across the 2 top terminals of that one and tab motor will most likely run and tab will retract. now, buy 2 solenoids. install 1 and have the other on board cuz you have no idea which one will bite you on the hiney next.

Yep, more than likely corroded contacts in the solenoid. I had the same problem with one of my HP1000 tabs. Replacements can be purchased at Napa. Echlin ST82.
