turn signal

[Steve & Leslie's Patriot]

I have a 2006 Jeep Wrangler I tow behind my RV. when I use the turn signals all lights flash in the back , and it is not very bright,but if I hook up a different car it works fine. So it must Be in the Jeep. Anyone have this problem, and have a solution

You probably have diodes in the lighting wiring and they will reduce the voltage to the lamps by .6v. Also, the wiring from the front connector to the lights may not be large enough, causing a further voltage drop.  You can't do much about the diodes but you can try larger wiring.

When you say all lights flash do you mean 1. that all the lights flash at the same time regardless of which turnsignal or brake is activated, or 2. do you mean that the correct lights work for the individual turnsignal or brake but are just dim.

If it is #2 then you do not have a good ground between the MH and lights on the Jeep.

If it is #1 then you have a wiring error or diodes backward or defective.

I took your message to mean that all the correct lights flash, but if it's really ALL the lights flashing, then there is a wiring problem.

all lights flash at the same time no mater what turn signal is on. but if I turn the turn signal on in th jeep It will work fine till the tires turn and the turn signal turns off in the jeep

I'm guessing they messed up the wireing,  Posibility is a bad ground but in this case I think they mis-wired

found the problem. when they but a new tow bracket on the jeep and moved the plug they did not hook up the ground wire correctly  Thanks for your help

WOW, it was a bad ground.. Now that, in this case, surprises me.

But at least I hit it with option #2,  Hit it with option #1 too (They messed up the wiring)

Ah, all problems should be so easy to solve.
