Electrical Issues- No running lights or tail lights.

[Amanda]

So I just bought my first pop up- we got it home hooked it up to the SUV had no lights except passenger tail light. tried a couple new fixtures and a couple bulbs. still nothing. checked all wiring from hitch to back end. Then my husband replaced the outside light by the table mount. All of a sudden everything worked for a second then gone.... now i have no lights outside. Where should i check next. Did he blow a fuse? Its a 1996 pop up with no ac and its a manual crank up.. Help we are hitting the road for 2 weeks in 2 days!!!

1. Corrosion in the TV connection.
2. Loose ground connection to the popup frame.
3. Corrosion in the bulb sockets.
4. Loose wires at any connection point.

Check your wiring and ground connections clean any corrosion on wires

Check all your plastic pigtail connectors. Make sure they're all pushed tightly together. Also, as tnchuck100 suggested, check the ground connections.

I feel stupid asking but what is the TV connection?

[Amanda]

i don't know how many grounds are on there but i have checked 3 and they were clean and tight.

The connector that you plug the popup to the tow vehicle (TV).

[Amanda]

Thank you!

if you lost all lights after replacing the bulb, it most likely is a fuse. as to how the fuse might have blown might be corrosion or some form of short at the light socket.

ok so i have checked all bulbs, all grounds, all fixtures. still no working lights. so when i removed the driver side tail light and looked at the wires i have a green and red connected and a white ground(that is grounded) when i look at the owners manual it says i should have yellow to my left tail light.
So from the front of the trailer i have four wires that run to the back green, yellow, red and brown, plus white for the ground so five. the connector for the TV is a 6-way(came that way) so we bought a adapter for our truck for it. we had a four way. any ideas why im not getting any outside lights now? help please!! so lost

[Amanda]

O and i checked all fuses, none blown

[bedrck46]

Do you have a meter so you can check the voltage at the connector on the TV check for running lights turn and stop Make sure you have 12v at each point Also How did you check the fuse Best way is to use a meter on volts or pull the fuse and check for continuity on Ohm scale I am not in favor of just looking at a fuse and saying its good. To me that is like if your engine doesn't start and you just look at the battery and say it looks good. Most all batteries look good but they may not test good. Test and be certain


Another thing is although your lights may be working on the TV some TV's have separate fuses for the circuits that go to the trailer connector
For example my expedition

I like bedrck46's suggestions

[Amanda]

i also have a ford expedition- we checked the trailer fuses with a meter- but i will check the ford for other fuses thank you all so much

[bedrck46]

what year is your expedition model and engine size

[emjayuu]

My Ford has a separate fuse in the engine compartment

[bedrck46]

the 1st gen expeditions the fuse is in the engine compartment but the 2nd gen expeditions the fuse in in the fuse block behind the passenger kick panel
