I hope this helps someone...I had a fast blink on my drivers front turn signal. (See attached photos) There are two 1057 bulbs in the housing. Use a flat screwdriver to pry out the assembly on the side of the orange lens.
Use a Phillips screwdriver to remove the black bulb holder from the housing, then twist out the bulbs. Examine the bulbs AND the contacts!!!
Thought it would be a dead bulb, but it turned out it was corrosion on one of the the bulb contacts inside the housing. I qrinded off the corrosion with a Dremel bit inserted into my Milwaukee drill.
When putting everything back together, I noticed 3 blade-style contacts for the harness. See photos. Where do the three contacts go to?
Can anyone supply a fuse diagram for my 97 xj6?



Front driver lens turn signal.

Two-bulb housing. Three blade contacts for harness in the middle. What are the blades connected to?

Thanks,
Ted

 

See page 21 as the fuse closest to the terminal post on the fuse box is # 1

and some uprated fuses for the external lights

Parker,

Thank you,

3 wires for the globes.
1 common ground.
1 positive for one bulb.
1 positive for the other bulb.

each bulb gets its own signal from the lamp control module.
I believe it is done this way for one of 2 reasons. (possibly both)
1 - distribute the power load to avoid potentially overpowering 1 bulb if the other blows
2 - this enables the bulb out detection to function correctly as it can tell accurately if just one bulb is out.

Good contact, bad contact.

Corrosion on contact

Thanks again, Parker and Spud. I am adding these four new photos to the record with descriptions. Hope it helps someone.

[size=18px]REMOVAL (updated)[/size]
[size=18px]Pry out orange lens with small flathead from the vertical side closest to the center of the car. Use cloth to protect the paint. After the turn signal assembly is removed, disconnect the wiring harness from the black bulb holder. Use a Phillips head screwdriver to detach the black bulb holder from the orange lens. You now have access to the bulbs. Twist them out gently.[/size]
[size=18px] I removed the bulbs. [/size]
[size=18px]Upon examining deep in the socket, I noticed corrosion on the bulb contact. See photos.[/size]
[size=18px]I grinded off most of the corrosion on the left side of the Jaguar driver turn signal bulb contact with a dremel grinder bit in the Milwaukee drill.[/size]

 

You may have to pull on the center contact out to make better contact with the bulb

Take a paper clip and pound one wire end flat , concrete floor works

Then bent the end of the flattened end 90 degrees

On installation you want to slather the contact with light bulb grease ( dielectric ) found at the auto parts store right by the register in small packets

The connector on the back of the assembly is of the form of a 3 wire EV - 1 as a 2 wire EV - 1 is used on the turn signals aft of the front tires

@ wire EV - 1 is also used for the trunk dome light and fuel injectors

 

PARKER,
Good advice, especially if the contact tab sits too low in the black bulb housing.
Will do your grease method next time a bulb acts up.
I got by with a 90° dentist's pick to pull up the tab from underneath, while simultaneously holding down the metal strip with a small flat screwdriver. (Didn't want to rip up anything in the black bulb housing.)

For all of you following this thread, one other thing I highly recommend, is using a multimeter to check for voltage and ground.

Now, if I can only figure out why my drivers seat won't move with working motors. LoL.

All the best,
Ted
