Its not get power. Take wire from the battery and hook directly to the unit.

Try reseating the connector from the control box to the LED control - there is not a positive lock mechanism (at least one mine) and the relies on friction - not the smartest design for a connector hanging upside down in an environment with lots of pounding :?:

Also, how do you retract your tabs? Are the setup to auto-retract when power is turned off to the engine or via a switch? There is an orange wire from the control box that goes either to a switch or spliced into the ignition. If the orange wire is not getting +12V I don't think the tabs will work.

Laser, im currently dealing with the same issue. If you speak with Lenco they will ask you to perorm (3) simple tests to identify the root cause.
1. Check voltage under load, if power dips you have bad wire.
2. Unplug connector from control pnl, using a paperclip link hole 3 to 5,6,7. If it works you have bad controller.
3. Hook acctuator directly to 12V power. If it doesnt work you have a bad accuator.
If all test pass, you have a bad control module, it is the brain board and Lenco is very tight with thier warranties. Good luck.

Also remember the accuator is a screw drive so if the tabs are not equal or you need them in a special placement you can always dis-connect accuator from the bottom where it conects to the plate and turn the accuator left or right to go up or down. My boat was stuck 1 side all the way up and the other all the way down so the boat listed hard left all day. Rec'd funny looks from other boats that day.

crap. im 15, i take engineering at school and build robots, not boats lol. I am going to need some help... could you guys dumb it down a little bit for me?

mwardncsu- they are auto or manually controlled from the helm. while they worked, i left them on auto and didnt have a problem. when i noticed the tabs stopped working auto i tried to work them manually, but the lights were out. I stopped my trip, had my friend take the wheel and put the boat idle into the waves. I tried to fix it by resetting the fuse, turned off and on again everything, but nothing.

I went to my boat this morning at low tide to make sure everything was good, and to make sure the tabs werent hitting. luckily they are fine, but i still cant get the tab control to come on. its really bothering me that its not working.


i need you guys to please explain everything as if i were...15 please :)

If you're building robots at 15 you're way ahead of a lot of us ;)

Sounds like you have the new auto-control Lenco tabs vs the manualmconol with LED indicator. Either way I expect there is a cable from the black plastic control box to the back of the control pad - make sure the connector is seated well.

Check your power/ground connections coming out of the control box - sounds like you've already checked the fuse itself. Break out your multimeter that ou have to build robots and see if you're getting +12V on the output of the fuse to the control box. If you don't have a multimeter then it's a wise investment for a boat (and building robots ;)) to get one and learn how to use it - very useful for many applications - I still have the one I bought from Radio Shack about 25 years go when I was around 15 :) - and actually used it last week when ringing out a nav light switch. Check the various connections that go to the wires coming from the black control box. At least make sure they are all connected, look solid and not corroded. Can't hurt to try reseating the connections that can be disconnected.

There will be two pairs of wire coming out of the control box to some Deutch connectors (kind of square, grey,waterproof looking connectors). These go to the Tim tab actuators themselves - unlikely to be your issue.

Otherwise, it may have to sit till Monday when you can call Lenco or your dealer. Be careful under there - even though it's 12V it can still pack a punch or you can short out or damage the gear worse - however nothing wrong with a little intelligent exploration - go download the manuals and trouble shooting guides from Lenco's website.

thanks mwardncsu, and i did some more research... they are called auto glide trim tabs. the key pad is suppose to be in constant comm with the box via NMEA 2000. when it looses comm, it pulls back the tabs slowly so no damage can be done, and the key pad at the helm and tower loose power and go blank. I need to check the connection (power and NMEA 2000?) between my stations, and the box.

quick question, when 2 tab control stations are to be connected to the actual box. if one station, say the helm, is disconnected, will the upstairs control be disconnected as well? because both dont work, does that mean both are disconnected?

thanks guys, wow the next few days are going to be tough, better learn how to wire consoles... bump?

You likely have a blown fuse somewhere. I had the same issue with mine, checked the only fuse I could find and it was good but when I dug deeper I found another fuse and it was blown. Lenco is great to deal with, give em a call to discuss the issue if u can't figure it out.....

Sorry, not familiar with the new Lenco auto system. Sounds like some other places to chase down including the NMEA network connections / power - any chance your NMEA network is powered on its own switch and that got turned off? The NMEA2K network usually has its own power node and thus fuse so check that as well.

Like the previous poster said, given Lenco a call today - if you can do it from the boat - and have them all you through things to check.

i checked my console again. everything seems plugged in correctly. I cant get a great view, and I dont exactly know what to look for, but the wires from the control box are connected.
attached are images from the console. the Lenco Auto Glide control is circular

you might have a bad actuator, I had to replace a couple do to salt water getting in them and corroding everything inside.

I had a similar problem and the problem was a loose connection at the fuse box. All I did was move the fuse to an empty slot and move the connection...problem solved!

The Lenco website has a troubleshooting guide and wiring diagrams that might help

could someone explain to me what an actuator is?? :roll i feel kinda dumb now...
and i sent emails to my dealer and lenco. looks like i gotta give 'em a call tomorrow...

Have you reviewed the troubleshooting info on the Lenco site? There are some good genera FAQ and info on trim tabs there that answer the question of what is an actuator - but in this specific case, the actuator is the mechanism that drives the trim tab up/down. It's a black cylinder looking object attached to the boat that has a stainless shaft coming out that is attached to the trim tab.

If both tabs are not functioning / responding then I'd be surprised if it is a single bad actuator and I'd be surprised if both went out at once - but who knows. I'd be looking for a bad connection or loss of power - or the control box may have gone bad (of course those auto tabs tie into other boat systems / NMEA network for engine info - so it may so be an issue elsewhere.

Call Lenco today, while at the boat if you can.

nice to know what an actuator is finally!!! but thats not the problem. The actual control box for the trim tabs is whats not responding. It has led lights, and they wont turn on. when clicking the buttons, they wont turn on. The tabs probably work, its got to be the wiring. The box is not getting power, therefore, no lights are turning on. I do not want to mess around with cables and fuses behind my console. What can I do?? I already reset the fuse multiple times, nothing. how do i replace it and how do i check to know if the power to the box is bad??


I will call Lenco tomorrow, there website gives nothing on the actual control box not turning on!
