mknherhappy Posted January 23, 2009 Share Posted January 23, 2009 My interior dash board turn signal indicators come on now when I push on the brake pedal. Any advice on whats causing this? Thank you. Link to comment Share on other sites More sharing options...
Pete M Posted January 23, 2009 Share Posted January 23, 2009 My guess is a grounding issue. If it was happening to me, I would start by inspecting the 4 taillight sockets and clean up the ground located behind the drivers side taillight. Then I'd move on to inspecting the front turn signal sockets. Link to comment Share on other sites More sharing options...
Red 1989 MJ Posted January 23, 2009 Share Posted January 23, 2009 Pete is right, you have probably a gounding problem In the DYI section, you have access to electrical manual. viewtopic.php?f=9&t=12734 Link to comment Share on other sites More sharing options...
Ed in North Ga. Posted January 23, 2009 Share Posted January 23, 2009 mines always been a front bulb- the goo is gone, and its just needs cleaning- its called ghosting, the turn signal/s kinda glow when you hit the brakes, or at night when the headlights are on. Last time it was my drivers side running lamp- remove, clean out accumulatied crap- replace-good for another little while. Link to comment Share on other sites More sharing options...
BLHTAZ Posted January 23, 2009 Share Posted January 23, 2009 I would definitely do as Pete says, but mine was the front sockets too. I found replacements for them at Auto Zone. Link to comment Share on other sites More sharing options...
702_MJ Posted January 24, 2009 Share Posted January 24, 2009 :hijack: Ok since we are on the topic of grounding out brake lights and turnsignals. My problem is when i turn the right signal on and hit the brake it stops completely, same with my hazzards. Could this be the same problem, ive been meaning to do some process of elimination but havent gotten around to it. Thanks Link to comment Share on other sites More sharing options...

mvusse Posted January 24, 2009 Share Posted January 24, 2009 Since the brake lights and hazards use the same filament, the hazards are supposed to quit working when on the brake. This is a DOT requirement as they consider brake lights to be more important that hazards. But turn signals should keep working when braking.

HKB3 Posted January 24, 2009 Share Posted January 24, 2009 I had the ghosting problem, it was a broken ground strap from the engine block to the body. I fab`d up a custom 1/0 ground cable & fixed the problem......now to finish the rest of the battery cables :wrench: Link to comment Share on other sites More sharing options...

This is a DOT requirement as they consider brake lights to be more important that hazards. But turn signals should keep working when braking. Not all cars function that way some cars have independant systems and the hazards still function while braking.Not only can bad sockets and grounding cause that problem but so can installing the wrong bulb .Installing a single element bulb where a double element belongs (and visa-versa) will short the two circuits and back feed and cause the dash lites or turn sig lites to illuminate. 30 years in the car biz you see it all. :nuts: Link to comment Share on other sites More sharing options...
mvusse Posted January 25, 2009 Share Posted January 25, 2009 Yes, cars that have independent brake and turn signal bulbs do keep working. But Comanches don't. Link to comment Share on other sites More sharing options...
garmj Posted January 25, 2009 Share Posted January 25, 2009 Yes, cars that have independent brake and turn signal bulbs do keep working. But Comanches don't. I know they don't.The statement was made that it was a Federal requirement and it is not. Link to comment Share on other sites More sharing options...
mvusse Posted January 25, 2009 Share Posted January 25, 2009 As far as I know if the same filaments are used for signal lights and brake lights, Federal Government mandates that the brake lights override the hazard signals. I still stand by that statement. If turn signals and brake lights are separate, brake lights can be on (not blinking) while the hazards are still blinking so my earlier statement does not apply. Brake lights HAVE to be on while braking. One is allowed to blink to indicate a turn, but not both. Link to comment Share on other sites More sharing options...
Jeepcom23 Posted January 25, 2009 Share Posted January 25, 2009 Alright I know you posted that Wiring book. But where are all of the body grounds for the electrical? Link to comment Share on other sites More sharing options...
702_MJ Posted January 26, 2009 Share Posted January 26, 2009 Ok didnt feel like working on the jeep today, its sunday, its raining I'm feeling lazy. Anyway a little sunshine came out and i decided to go wash the truck, get all the sea salt off and stuff. But when i was done and went to the dump to drop of trash, i noticed that the tail lights were on. Checked to see if i pulled the lights on and nope i didnt........could i have shorted a wire washing it? Is this that ghosting thing you all were talking about? Or is it time to get new bulbs and new connectors, and if so where can i get the connectors? Or time to check some grounds? Electrical aw you gotta luv it :fs1: :wall: :grrrr: :headpop: :help: Link to comment Share on other sites More sharing options...
