I am attempting to get the lights on the boat work with the trailer lights. Something was wired wrong from the beginning. I believe I still have problems. I have a brand new ez-loader trailer that was wired for the boat at the factory.
Here are my questions...
Are the side lights marker lights only? Are the rear lights turn signals only?
And here is what is happening...
I have swapped a couple wires at the bow. I now have a left turn signal at the rear with all four leds flashing. The marker light on the right comes on with the marker lights but only 2 leds come on. The right rear led does nothing but 2 of the leds barely glow. The left marker light flashes when the right turn signal is used.
Anyone know if these are tested at the factory?
Hello David,
The LEDs on the 21EC are "clearance" on the yellow side markers. The "tail" lights show both "brakes" and "tail" lights.
The side lights DO NOT flash with the turn signals. This is based on my 2013 model.
Now, a few questions:
HOW are you testing these lights? The boat is ON the trailer...but is the trailer HITCHED to the tow vehicle? IF not, I would get it HITCHED up since ground problems are a frequent cause of goofy trailer lights. I know, I know the light plug to the tow vehicle is SUPPOSED to carry a ground wire, but...it doesn't always work. Thus, the BALL-TO-HITCH connection becomes your trailer lights ground.
Since you didn't report on the function of the trailer's lights, I assume they worked appropriately during your test? Please confirm since ASSUMPTIONS cause all sorts of misery in life...especially with trailer lights, like when you think your should be able to just back the truck up and connect the light harness...not even mess with hitching up the ball...oops...BAD ASSumption...lights act all screwy, some half on others blinking when they shouldn't, etc. because the ground is hinky... DAMHIKT...
In my situation, the original owner cut off the harness from the trailer to the tug, so I made a new one and wired it up. Simply matching the wire colors to the boat's plug the same as the trailer's plug worked. Crawling around the innards of my boat revealed what appeared to be a LOOOONG trailer light harness just like what you would use to wire a boat trailer. So, the colors should match...from plug to plug.
Make sure you have the vehicle grounded before you mess with any connections in the wiring harness. This means HITCHING the trailer to the tow vehicle and latching it down good.
Let us know what pans out, OK?
Good luck,
