trailer lights shorting - any advice?

9 posts in this topic

There was a discusion on this very subject not to long ago.Try a search for it maybe use trailer lights or some thing like that for the modefier to search with.
Other wise just keep reading back page by page, it was maybe two or three weeks at the most since it was up.
You may have to re-wire the trailer.
Does the tow vehical have a tow package?
It may need a higher fuse to comp for the added load of the trailer lights, but don't go to high as you could burn out something else.

P.S Check the grounding of the lights as well!

With an ohmeter, touch one lead to chasis on the trailer and the other lead to your brown trailer wire. If there's continuity with zero resistance, you have a direct short. I doubt it. You should get an ohm reading of the running light circuit. I'm guessing the problem is on the truck side. Follow the brown (running light circuit ) from the plug back to it's source and check it carefully for nicks or bare copper. Alot of times, it's a crappy install problem. I also highly doubt your overloading the circuit unless you have that trailer lit up like a xmas tree, besides it used to work right?

Hoping someone smarter than me can provide some assistance. The trailer lights for my 1998 Alumacraft work fine during the day, but once I turn the nighttime running lights of the vehicle on, the fuse on the vehicle for the lights shorts out, thus rendering my vehicle taillights and boat trailer lights dead. I've checked the groundwire and it appears ok, although perhaps not good enough to handle the extra current burden when the running lights are turned on... Any advice out there to diagnose and fix this problem? Thanks much!

I had the same problem with my GM pick-up, day-time lights worked fine, but night-time lights would blow fuses. After pulling my hair out trying to find the short, I just re-wired the trailer and haven't had a problem since. Simple fix for a frustrating problem. Now I just have to worry about sun-burning my bald head.

Trailers are so much fun. I just rewired mine. Have tail lights. Have both blinkers. NO BREAK LIGHTS. Ugggg. I am almost thinking its a problem with the truck and not the trailer.

They have a variety of trailer wire kits at WalMart for well under 30.00. Check them out if that is what you decide to do.
Good luck.

I'm not an expert at wiring, but I do know if you have both signals, you should have brake lights. Do you have the 4 wire system? One wire is the ground, one is the tail and the other 2 are signals/brake. Have you tried testing the plug on the Truck end, that will tell you if the Truck is the problem. Just an idea, hope you solve it.

Thanks everyone for your input - it was indeed the ground connection on the truck - I didn't want to believe it, which is why I spent so much time on the trailer. Darn thing was corroded and rusted pretty bad! Good luck all.

If your truck does not blow the fuse when the trailer is not connected, the problem should be in the trailer side of things.

There is probably a dead short to ground in one of the light assemblies on the trailer.

The gentleman who suggested the trailer rewire option is right on the money. Factory wiring and light assemblies are usually not top of the line. Aftermarket is the way to go.

If you dont want to go that route right now, try this: Open up and remove EVERY light bulb from the trailer. Hook the trailer up to the hitch and connect the harness up to your truck. Turn on your running lights, and see if the truck fuse blows. If it does, the short is probably between the hitch harness and the first light assembly. If the fuse does blow, put the bulbs back in one by one until you blow the fuse. When the fuse blows, look very closely at that light socket/assembly.

Good Luck.

I was having the same problems so I brought my boat in for a complete rewire from the plug back to the lights. The problem resurfaced after the re-wire and I thought I was going crazy. After bringing the boat in and having the marina check the check the connections again one of the guys told me that one of the wires in the trailer was original. That pis@ed me off and the guys at the marina told me they would rewire the thing again and finally do as I asked for "free". Everything works fine now.

I should have done the re-wiring myself but I was having boat work done at the time.

I would just buy what you need and rewire it yourself. Tie the new wores onto the old wires and use them to pull the wires through the trailer if possible. You will probably find some exposed wire somewhere on the old wires.

    • Glad to hear you're back up and running again.          
    • I got my boat back today and it runs great now but the mechanic said I had too many idling hours on it and it had a lot of carbon build up. I have trolled a lot with this motor . It has ran great but I did have  this recent issue with it where I had to bring it in and it runs good now. Mechanic recommended run it more often at higher rpm's.  For those that troll with their main engine,  how often do you run in a higher rpm's? I  use carbon guard  and thought that that would prevent the carbon buildup.  If I trolled for three or four hours at a higher RPM would that be too much ?          
    • Saw some reports from Algoma that looks like fishing has picked up some out there and some bigger fish being caught. I'm not ready for snow yet but I hope we actually get some this year. 
    • Well I got it done. I got some bolts washers and rubber grommets. I drilled holes in the counter top. then brought the bolt up through it put a 1/2in rubber spacer then a washer and bolted right into the bolt holes where the leg levels went. It looks nice and will be nice not having to put the fridge up and down every time a guy moves the ice castle and should hold fine driving down the road.         Nice exactly what I need to finish the project, so the fridge door doesn't fly open when driving down the road.

    • The boat is getting lots of use,,,, Heading to Algoma july 29th and back to Isle Royale later in august 
    • You're bolting a mini fridge to a countertop but worried that a tie down strap will make it look trashy? OK then.
    • The strong rainfall of the last few weeks was compounded this week with more rain accompanied by high winds, thunder and lightning, as well as several tornado watches across the state. Downed trees and branches and flooding was reported at numerous state properties throughout south western and south central Wisconsin. State park crews were actively clearing roads and trails, and we're expected to have additional updates before the weekend. Anyone planning on visiting a property in these areas is urged to contact the property directly for the latest conditions.Water levels across the state are still elevated and this week's rains means sand bars will likely be in short supply again on the lower Wisconsin River. With the high fast moving water many kayakers and tubers are taking advantage of the situation. A group of kayakers on the Peshtigo River said with the fast water they shaved an hour off the time it normally would take them for a river trip.Wild weather has put a damper on fishing pressure across the state and there are isolated reports of partially submerged fishing piers. Anglers have reported some success for catfish on the St. Croix River and anglers have been having success fishing the Flambeau River for musky, walleye, northern pike and bass. Largemouth bass fishing has picked up with high waters in Dane County rivers and there were reports of an uptick in walleye and perch are coming in from Lake Winnebago. .
