When towing there’s a little more to it than just installing a hitch. You will need to ensure that your trailer hitch plug wiring lights are correctly installed. And sometimes that can mean some troubleshooting is required. Here are some common questions that arise.
1. What is a converter used for?
Two types of taillight designs are made for vehicles. One uses a common bulb system and the other an independent bulb system.
A common system means the turn signals and brake light use bulbs that are separate and independent. This is the industry standard for towing. If your vehicle has an independent bulb system you will need to use a convert to convert it to a common bulb system for the purpose of towing.
2. Why am I blowing fuses?
If you are blowing fuses on your vehicle you need to check for any wires that might be touching bare metal, pinched, or where there might be bare copper.
You may also need to calculate the amp load your trailer is pulling. You vehicle should be able to handle standard lighting on trailers such as turn lights and brake lights but check your owners manual for the exact ratings. If you can’t find a pinched or shorting wire and your vehicle rating is adequate then you should consult your local dealer.
3. Do I need to unplug my lights before backing into the water?
When launching your boat you should always unplug your trailer lights before backing into the water. If you submerge the connected lights into the water it can short out or cause the fuses to blow.
4. What causes my brake lights on my trailer to go out if I have my headlights on?
This means you have a grounding problem. Your ground may be strong enough for some light function but it is not proper and thus when there is a maximum amp load it fails.
Check your connector on the vehicle. Make sure the ground is secure and that the wire is attached where there is no paint, rust, or undercoating. Make sure the connection is secure. Make sure that each tail lamp is individually grounded. Be sure to also check the trailer to ensure there is not a problem with the grounding on the trailer itself.
These are just a few of the most basic problems that can arise and these troubleshooting tips will have your trailer hitch plug wiring lights up and running in not time at all.
