Lenco Trim Tabs Not Working

  1. Power Issues With Lenco Trim Tabs

There have been many reports regarding the trim tabs not moving after users try to use the controller. Many factors contribute to this issue, and most of the time, it can be fixed by replacing some kinked wires.

So, there isn’t much to worry about if your unit is relatively new.

There is a good chance that it will be fixed in no time after you inspect the wiring cluster and set aside broken wires. All you need to do is isolate the broken sections and replace the wiring going into the HPU.


In most cases, observing the cables allows people to isolate the issue.

This is because small breaks or cracks can be noticed easily. You can then replace the cables with new ones. On the other hand, if you are having trouble then you can also use a voltmeter to take readings of the current.

This allows people to isolate broken or damaged wires easily.

If you don’t already have a voltmeter with you then make sure that you purchase it. While borrowing it is an option, it is much better that you purchase one yourself.

This is because the tool comes in handy when trying to isolate electrical issues like these.

Similarly, inspecting the status of the fuses is also a good option for users that have wiring in perfect condition.

Both of these troubleshooting steps are quite cheap, and you won’t have to set aside any extensive budget to fix the problem.


However, if the issue is still there after you’ve replaced the fuse, then your best bet is to clean the connection points with a diluted vinegar solution. After that, just secure the connection points properly and try to use the controller.

Hopefully, everything will be fixed at this stage, and you won’t have to bother with the power issues again. Keep in mind that the fuse being installed should be supported with the electrical ratings on the Lenco Trim Tabs.

  1. Trim Tabs Stuck Or Not Extending

It is also quite common to see users struggle with the full extension of trim tabs after using the controller. If you’re in a similar situation and the trim tabs are not fully extending, then you’re dealing with voltage issues.

To get a better understanding of the issue, you need to check the voltage with a multimeter. Make sure to check the reading on the battery terminals and the connection points on the HPU.

If the voltage levels are below 10 volts during normal operations of the trim tabs, then you’ll need to get a battery replacement for your unit.

Unfortunately, battery replacement can be somewhat expensive, and you will have to set aside a substantial budget to troubleshoot this problem.


On the other hand, you can always try inspecting issues with the hydraulic lines. There is a possibility that you’re struggling with extension issues because of defective hydraulic lines.

So, if the voltage output is optimal, then you should call Lenco customer support to isolate the problem.

Hopefully, that way, you’ll be able to fix this issue quickly.

When it comes to the battery, another thing people should check is when the device was bought. If your battery is new, then there is a higher chance of something else being wrong with it.

On the other hand, if the battery was old then it will require a replacement. This is because these tend to lose their total amount of capacity over time. When it comes to troubleshooting a battery, people can start by checking the terminals.


Make sure that the wires on it are tightly attached. Once done, let the battery charge for some time and then test it. If you notice that the terminals were covered in dust then make sure that you clean them properly.

If there is rust formed, then using a solution of water and vinegar should help you out.

Scrubbing the surface using a toothbrush is necessary if the rust was too old. It is recommended that people keep the terminals clean at all times so that problems like these can be avoided in the long run.

  1. Actuator Problems With The Device

It is not that rare for users to run into issues with the actuator.


If you’re struggling with a situation where there is nothing wrong with the wiring cluster and connection points, but the trim tabs are still not working, then you’re likely dealing with a defective actuator.

The only way to get around this issue is by purchasing a new actuator to install into your trim tabs. With that said, if your purchase was recent, then it is a better idea to call your dealer.

That way, you can forward a warranty claim if it is still valid.

Otherwise, you’ll have to spend a lot of money to purchase actuator replacements for your trim tabs. So, go over your warranty status and manage your budget accordingly to get professional help.

All in all, these were a few issues that you can expect with Lenco trim tabs.

While some of these issues can be a little tricky to maneuver, you’ll be able to fix most problems by managing the wiring connections.

If you’re unable to isolate any problem, then the professional working at Lenco will help you narrow down the issue.

So, make sure to reach out to customer support if you can’t solve the problem. The team will ask you some questions regarding the problem that should be answered carefully.


These should help the team in ensuring that they can fix the issue as soon as possible.

In some cases, the problem with your device might be a faulty part. You can isolate the issue on your own, but it will take a lot of time and effort. To prevent all this hassle, it is much better that you contact the support team instead.

The faulty parts can be replaced by simply sending the Lenco Trim Tabs back to the brand. This should take a few days to get fixed, but your problem will not appear again.
