No Running Lights...HELP!!

Hi everyone...

About to get on the road so i decided to replace all the lights on the exterior of my trailer.

The problem is now all the running lights do not work.

Heres what i have checked so far:

1. took apart the 7 pin. not it.
2. checked all lights for good ground. not it.
3. Tow vehicle is 08 tundra. checked fuses...not it either
4. screamed.several times...did not help. but felt better.
5. cleaned connectors of all 7 pins with wire dryer...nope.
6. post to the forum...for help...

If anyone out there has any suggestions. I will say the rear running lights were not working prior to my changing them out...

The turn signals work fine. the brake signals work fine.

All running lights are on vacation.

It feels like a no power issue, or blown fuse...but is there a fuse on the running lights?

Help me...

Get a test light, find out where you have power and where you do not.

My guess is that somewhere in the process you made a short to ground.

There will be no fuses in the trailer connected to the parking lights. Any fuse related to the parking lights will be in the truck and will effect the truck as well.

You have to start at the truck 7 pin connection and test to see if you have voltage on the tail light pin. If not the problem is in the truck. Then go to the end of the umbilical inside the trailer and test the green wire at that point. If not the problem is either in the male plug or in the umbilical itself.

I am sure you will find the problem before that point because that is the last place that all the parking lights have in common.

When I picked up my TT for the first time, the connections had all been perfectly made, but the fuse under the hood of my TV was simply not there. Popped in a fuse and bingo.

HowieE is right, the TV supplies power for the running lights, not the TT.

No Running Lights...HELP!!

I dont know about this Toyota, but I know at least some Dodge prouducts and at least some GM products will have truck and trailer lights on separate circuits.

So it may be possible that truck running lights work and the truck will not supply power to the trailer. This used to be accomplished with fusing, but now Ram does it through a "buss".

It kind of sucks that simple fusing has been abandoned. I don't know how Toyota does this....

Like I said, get a test light you will not regret doing so,

When you know where you have juice and where you do not fixing the issue becomes much easier.

Sooooooo...still not finding the problem.

Today i pulled all the lights...re tapped them over the shrink wrap...just in case.
Then got the circuit tester from Orilleys and begin testing all fuses.

All the ones in my tow vehicle are fine. 08 tundra has 3 - 30a in the engine.
Turned the truck on and checked the umbilical...only 2 are showing active.

the top two on the truck which is the running lights.

so not it has to be the trailer.

If one of the lights are bad then all the lights are bad? is that how it works.

do i need to take my light thingy and go through all the lights with the trailer hooked up?

will that show me the problem light?

Or is it the truck. If only the top two are showing power is it a bad relay?

With the plug wedge at the top, the top 2 pins should be hot. The ones at 3 and 9 are turn signals. If all of these are hot on the TV, then the problem is between the umbilical plug and each light. Since the turn signals work, there must be an open in the common wire for the running lights.

The lights are not in series. even if only 1 is good it should still light. Your problem is in the common trailer wire for running/license lights.

Does a single wire matter on the lights? Its one line in and grounded on one screw, i should post a picture...theres one plug that comes in from the trailer connected to the light and the other one is ground to the screw.

Is this the wrong lights...?

First answer this question. With the tail lights turned on and the truck running.

With a test light or bolt meter touch the 2 terminals at the top of the receptacle on the rear of the truck.

Do you have voltage on both?

If yes turn the tail lights off to confer magicked is the tail lights

If you do not have voltage on both again turn the tail lights off to confirm. If you loose voltage on that terminal.

I ask it this way because some newer trucks do not apply voltage to the battery charge circuit until the truck is running
