Big(Crusty-old-man <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> )Jim,
I went down to the local parts store and got the HD flasher and they were nice enough to take it back when I went up to the "Super HD" flasher. There was no difference with either change.
I have used the stock one that was origionally installed in June 1991 at the factory. I have replaced it with a Heavy Duty flasher, and then swapped it out for a really snazzy plastic cased deal with lots of copper wire wrapped around inside it, will take picture if you want....
I think this is something other than the flasher. I do a bit more towing than normal Jeepers would put a YJ through, so I feel that making this right would be the best way to go.
I have the trailer light harness soldered in just inside the tail "door" on the left right where the wiring harness comes back along the side of the body just before the door latch post mounting assembly. The ground lead is a soldered line that goes all the way to the ground terminal of the battery....
I can see how running a pair of relays would do the trick, but don't see that I should have to do this....
Jim, the flasher thing is a good thought, but I have eliminated the chance that I would need to "upgrade" the flasher.... What next?

Maybe the trailer has a crossed wire problem.. How does it work with NO trailer? Did the solder dude hit the correct wires? Big JIm <img src="/forums/images/graemlins/pfft.gif" alt="" />

Okay, perhaps I need to repost the origional post.... I did the soldering and got the wires right. They blink, just not correctly. With no trailer lights attached, Standard lights work fine, only when trailer lights are attached. I have used other trailers, other lighting methods, and all give same results.... See below for origional post: Problem:
When I hook up something to tow behind my Jeep, the turn signal lights flicker rather than flash. Just the turn signal lights....
Not a problem:
running lights are fine, bright as can be, same for brake lights - they are about the same as the 4-ways, they work fine as well
Thoughts:
I have a Super HD flasher and a 15 amp fuse.
Towing wiring harness ground on Jeep is connected to the neg term of battery.
Other wires are solder spliced to the origional wiring harness for the tail lights.
All trailers towed have grounded light fixtures, hardwired into the ground lead on the harness.
All trailers towed don't have this problem when towed behind (SHUDDER) the ford ranger, explorer or the buick.
I have tried:
Verifying ground is good
used several different light set-ups (mounted, unmounted, magnetic mount)
upgraded flasher from stock to HD and even tried a Super HD one....
Tried different trailers
Surely someone has a simple answer for this one....

before you go through the trouble of relays, try pulling the bulbs out of the taillights on the jeep while the trailer is jacked in. less draw on the system, maybe that will tell you something.

Ok then I had a problem once similiar to this with one of them big trailer plugs! Take the thing apart and clean it out and observe the connectors for a stray connection.. In my case it was some dried mud had got in there and I could ohm across it! Big JIm <img src="/forums/images/graemlins/pfft.gif" alt="" />

NY, I will try this just for the heck of it. I'm betting that the trailer lights will work fine that way, but I can't keep yanking bulbs and sticking them back in every time I need to tow something. I guess a last resort would be to disable the turn signal elements in the tail lights when I'm towing, but that is going to create a safty issue almost as much as taking the bulb out. Will use this in a troubleshooting thing though.

I'm going to town. I will pick up a new harness and resolder it in and after doing the bulb-pull thing will post findings. Till then, I have a tank of fuel to burn off.... More later.

Checked the contacts, they were okay, but changed the line out just the same. Solder connections are and were fine. Pulled the bulbs out of the tail light assy's and the trailer lights worked like they should.
The fuse is 15 amps. It should be a 15 amp fuse based on the wiring diagram as well as the fuse block print.
Only thing I haven't done is get one of them Sunder California special hazard lamp flashers and try that. If their pin config is the same as the flasher, then this may the the solution, or maybe not? grrr....

YOU HAVE THE WRONG FLASHER MODUAL!!
Everything you are saying is pointing to an over currenting flasher module. Get a proper hazard flasher or a true HD flasher (hazard flasher in disguise). You can keep pulling bulbs and rewiring.. ETC until you turn into an old gray haired man, the problem is current. Why do you think it worked normally when you pulled the bulbs?

Just so everyone knows, the relay idea was an extreme idea of a fix. I definatly agree with Sunder. You do not have a switch/fuse that is capable of handling the additional load. I didn't know about the hazard flasher but it makes complete sense due to the fact that is capably of handling four lights. Cheers, RJ <img src="/forums/images/graemlins/cheers.gif" alt="" />
