• Will a Dead Battery In the Breakaway Box Cause Trailer Brakes to Not Disengage?
  A dead battery would not be the cause of your brakes not disengaging. A dead battery would have the complete opposite effect on your brakes. A dead battery wouldn't send the electric signal to engage the electric brakes and no electric signal would mean no brakes at all from the breakaway standpoint, but you will still have brake signal from your brake controller. When you connect your tow vehicle, that will send signal to your trailer brakes only when the brakes are engaged on your...

• Installing Dielectric Grease on 7-Way Plugs to Prevent Corrosion and Keep Electrical Connection
  Dielectric grease is basically just applied in a thin coating to the connector plug. You can use # 11755 or # LT37534 if you prefer a smaller amount. I've attached a video to assist. Just like the connection on the back, you can add this to the trailer pins on the front of the connector as well to keep moisture and debris out to prevent corrosion. I've attached an article to help as well.

• Trailer Light Fuse in 2004 Chevy Silverado Blows When Any Trailer is Connected to 7-way
  Since you have the issue with your truck's trailer left turn fuse blowing no matter what trailer is connected, the issue is likely to be in the truck's 7-way socket or the wiring leading to it. Corrosion can build up in the truck's 7-way socket - either on the pin contacts themselves or even inside the back of the connector - and this can cause two circuits, such as the trailer left turn/brake circuit and the 12V auxiliary trailer power circuit, to become bridged together. The round U.S....

• Updates To MaxxAir Replacement Printed Circuit Board # MA10A21275K Version C
  I reached out to MaxxAir for the Replacement Printed Circuit Board # MA10A21275K and any updates. The current C version has been updated with better resistors to better regulate both voltage and amperage. It does include a coating for corrosion resistance from moisture on the board itself. Be sure to use Dielectric Grease # LT37534 on the connectors since they are not coated otherwise it would interfere with the connection.

• Recommendation for a Brake Controller to Fit a 2009 Chevrolet Tahoe
  Depending if you already have a 7-way connector installed or not on your 2009 Chevrolet Tahoe will determine the amount of additional parts that will be needed when installing a brake controller. First, the Tekonsha BRAKE-EVN # TK63VR, that you referenced is a quality controller that will work well with your Tahoe. If you already have a 7-way trailer connector installed on your Tahoe, then all you will need is this brake controller and the included wiring harness. The needed wires to...

• How To Hardwire A 4-Way Harness On A Small Utility Trailer
  In order to wire a 4-way harness onto your trailer, you will need a few simple items. The first of which will include our Deka Heat Shrink Butt Connector part # DW05744-10 and the Electrical Connector Dielectric Grease part # LT37534. The rest of the tools needed for this install should be fairly common in most toolboxes. Before you install the wires, you will need to strip back a 1/4" of the jacket from each wire and place them into opposite ends of the butt connector. After you have...

• Protecting Trailer Electrical Connections from Salt Water on a Boat Trailer
  What I recommend doing is wrapping electrical connections using heat shrink tubing # DW05452. This will keep on the water and preserve the metal connectors from the light. I also recommend using dielectric grease # LT37534 between electrical connections to repel moisture. I also recommend running a jumper ground from the light ground location somewhere further up on the trailer (at a spot that won't be under water) so that the ground is not affected. If at all possible, rinse the trailer...

• Charging Trailer Batteries While Towing Using the Alternator in a 2016 Ford F-150
  The problem with charging trailer mounted batteries is that vehicle alternators and the wiring going through, say, a 7-Way trailer connector cannot push back the amperage required to charge up the batteries (or it would take an extremely long time). At best they can maintain the charge level in most cases. But there is a solution to that issue and it is actually similar to what you have suggested. What you need is a DC to DC charger. We do have one rated at 40 amps, # 331-BCDC1240D, which...

• Replacement 7-Way Blade Metal Trailer Electrical Connector Options
  Yes, we have the Pollak RV 7-Blade Plug End Socket w/Mounting Bracket # PK12-704. It will require you to cut off your current connectors to wire in the new ones. I recommend using Loctite Electrical Connection Dielectric Grease # LT37534 on those connections to keep them protected.

• Process for Replacing Broken 921 Bulb in 2004 Surveyor
  A small bulb like the 921 type you referenced, part # VA0415-00, is a friction fit in its socket. The bulb is removed by grasping and pulling it straight out. In your case since the bulb is broken you'll need to be careful to avoid cuts and you may need something other than your fingers to get at the remaining parts of the bulb. There are pliers available that have cushioned jaws to allow gripping brittle items, but if you do not have such a tool handy you can use a piece of cloth between...

• Running Lights On 5th Wheel Trailer Not Working on 2016 Chevy Silverado 3500
  Usually when there is a function that is not working on a trailer the most likely culprit is a dirty or corroded trailer connector. Make sure the trailer 7-Way, the new 7-Way, # 50-97-410, and where the new 7-Way Tees into the bumper 7-Way are all clean and free of corrosion inside, where the wires attach, and outside on the pins. While it is unlikely the connectors on your 2016 Chevy Silverado 3500 are corroded it is still worth taking the time to check the connections. I also recommend...

• Troubleshooting Difficulty Installing Replacement 921-Type Trailer Light Bulb
  Trailer light sockets, such as those intended for a 921-type bulb like # 30-90-021 do use friction to hold the bulb in place in the receptacle. This can mean that a new bulb may present a fairly snug fit. You might try using dielectric grease like # LT37534 to both protect the socket and bulb contacts from potential corrosion and to act as something of a lubricant for installation. You can also check that there is nothing from the original bulb base still inserted in the socket. It can...

• Troubleshooting No Power to Monitor in Hopkins Smart Hitch Backup Camera HM50002
  Both the camera and monitor portions of the Hopkins Smart Hitch Backup Camera # HM50002 receive their power from the vehicle's reverse light circuit. This circuit is accessed when the round U.S. Car connector is plugged in at the factory 7-way. Both the camera and monitor should turn on and off when the truck is shifted into and out of reverse gear. If your truck's reverse lights work then no other fuses or relays should be required. The monitor's cable plugs in to the camera assembly...

• Are Quick Splice Connectors Weather and Water Proof?
  The Quick Splices - Self-Stripping Connector - Closed Port - 14-16-18 Gauge - Blue - Qty 1 # SWC502905-1 is weather proof and water tight, but not waterproof. To further assist I recommend adding dielectric grease # LT37534 to further protect the splice from water and debris. As long as the grease remains as a protective layer, you won't have issues but it isn't recommended to submerge. If you are looking for a submersible connection, I recommend the Deka Heat Shrink Butt Connector -...

• Troubleshooting Brake Lights and Turn Signals on 2000 Ford Excursion With 7-Way
  Since everything worked when you hooked up your trailer to another vehicle we know the issue is with your 2000 Ford Excursion. The most likely issue is that you have a blown or missing fuse so check Fuse Location 13 in the Passenger Compartment Fuse Panel and replace as needed. I do recommend checking your owner's manual to confirm this is the location. You will also want to check your Excursion's plug for corrosion, which can be green or white in color. A build-up of corrosion can interfere...

• Recommended Solution to Extend a 7-Way to 7-Way Connector from a 2006 Lexus LX 470 to Pop Up Camper
  The TorkLift wiring harness extension # TLW6028 will be a short term solution or if it's an occasional fix. The reason I say that is because it opens up possibilities of problems. These problems could result in becoming disconnected, additional connection points that could get dirt and grime in the connector to name a few. To avoid some issues associated with corrosion on the connection points you can use dielectric grease # 11755 or # LT37534 that seals out moisture and prevents corrosion....

• Trailer Brakes on Airstream Trailer are Weak Even After Adjusting Them
  Usually when the brakes start to get weak it is because they need to be adjusted. If you had them adjusted and the problem persists it could be a problem with the brake magnets. First, you can visually inspect the magnets and if you can see the windings coming through they will need to be replaced. To further test the magnets you can follow the help article I have linked. Inspect the wiring to the trailer brakes, the magnet ground wires, and the trailer connectors on truck and trailer....

• Troubleshooting Trailer Wiring Running Light Circuit on 2005 Toyota Highlander
  Since you've tested your trailer with a direct 12V power source and confirmed that it is not the problem, I suggest you first focus on the item that is most often the cause for the kind of issue you describe: the trailer wiring harness ground wire. If the ground on the Highlander's wiring harness is not solidly affixed to a clean bare metal surface it may be able to pass enough current for on-and-off signals like brake and turn lights but may not be able to handle the steady current draw...

• Potential Grounding Issue When Installing Peterson License Plate Light # PM436B
  Thank you for your recent purchases from etrailer. A bad or insufficient ground is among the most common causes for issues with trailer lighting. The Peterson License Plate Light # PM436B that you have does use its steel mounting surface to make the ground connection required for proper operation. Connecting the lead wire to the brown wire for the running light circuit as you did is correct. Please see the linked video for reference. You can sand off paint from the trailer frame where...

• Protecting a Trailer 7-Way Connector While Trailer is in Storage
  Covers for 7-Way trailer connectors are very uncommon and the only ones we have are attached to powered jacks. An inexpensive solution would be to use a small battery box such as # TK2051 and slightly modify it so you can put the 7-Way in it. I also recommend adding some dielectric grease, # LT37534, to repel moisture.

• What Does the SH Error Code Mean on the Tekonsha Prodigy P2 Brake Controller
  The SH code on the Prodigy P2 Brake Controller # 90885 is indicating a short in the brake output circuit. A dirty or corroded trailer connector can cause a short. First,clean out any dirt or corrosion you find. Corrosion can also build up in the backs of the connectors where the wires attach. Once cleaned, use a dielectric grease, like # LT37534, on both ends of the trailer connection to reduce any future corrosion and dirt or water contamination. Since you only have noticed the problem...
