Hello to all vanning people from Finland smile

Having problems with stop lights. Turn signals and hazard warning are working but not anymore stop lights.

Have followed instructions from my Chrysler 1986 Service Manual for making " Checking continuity".
'
Fuse 7 is ok. Where can I locate splice called M1 ? Good grounding with extra soldered grounf wire. Bulps are working ( measured with ohmmeter ).

Opened physically stop lamp brake switch - it is working without problems. There is 6 wires. Manual is telling these colors but car has different colours.



Manual tells 18 White o o 18 Pink these are connected when brake pedal is not pushed
____


18 Dark Blue o____o 18 Dark Blue these are connected when brake pedal is not pushed

18 White / Red o____o 18 White these are connected together when after brake pedal is pushed



In my Dodge RAM Prospector year 1989 V8 318 with automat transmission

18 Dark blue / Red o o 18 Yellow / Red these are connected when brake pedal is not pushed

____

18 White / Red o____o 18 Black these are connected when brake pedal is not pushed

18 Dark Green o____o 18 White these are connected when brake pedal is not pushed




Continuined - when brake pushed then wires

18 White / Red ----- 18 Black and 18 Dark Green ----- 18 White

are connected.


When not pressing brake pedal 18 Dark Green and 18 White have connection.

Disconnected turn signal harness from body wiring harness. Measured with ohmmeter.
Ohmmeter is working. Using multimeter on ohm are. Probes are good.

Does anybody have picture or information about these wires that are soldered to plastical component with plastic window in steering column ?

I am not so pretty good with english either write or listen. Trying get help.

Need to fix my brake lights. I am retired. Have been working as electrician but not with car electricity.

Hope that somebody could give some help with this issue.

Here in Finland cars older than 3 years must be inspected every year.

if you have ice and snow and a trailer harness, re check all the connections underneath. The #1 cause of lighting issues is separating and grounded out trailer connections.

Brake light switch is on the pedal arm under the dash usually . Make sure its working testing with a test light.

Thank You for hints. Should check trailer harness. I fixed that problem from my friends car.

Usually at this time of the year we have had snow. But now there is nearly no snow compared to earlier years.
We live in quite near middel of Finland.


Tested brake light switch. Measured with a help of multimeter/ ohmmeter. Opened whole switch for checking bad connection. Everything is clear and clean.

Wonder ( don`t know the name to this combonent which is installed in the steering column, I call horse shoe) if in this combonent is some problem.
In year 2016 had problem instead brake lights with turn signal lights. Changed places with white and dark green wire.
Situation was fixed. I didn`t own yet that time Chrysler Service Manual for 1986 RAM VAN.

Should continue with my car issue.

Merry Christmas

Henkka, welcome!

Here's a few more possibilities.

It might be worth making certain that the metal tail light reflector baskets are grounded properly. On many of the Dodge vans, a single screw which retains the tail light lenses acts as the electrical ground for both tail lights. On my Dodge van, the screw is on the passenger side tail light. If you can access the rear of the basket, you'll see a ground wire leading to a clip on that screw. Corrosion or using an incorrect screw may cause a loss of electrical ground to both baskets. The original screws are different than hardware store screws.

I've also seen the sockets may become damaged internally, especially the spring-loaded contacts. They may become deformed, their springs may fail, or the fiber plate may become partially punched out.

There is a more annoying and misleading issue I've encountered, where the inexpensively built Chinese light bulbs electrical contacts may not extend far enough to reach the electrical contacts in the sockets! If you can access the rear of the sockets, you can watch to see if the spring-loaded contact pins move as you insert and rotate the bulbs.

Best wishes!

Hello again, now brake lights are working, but when I push brake pedal getting indication in cluster that I´m turning to left.

Once in year 2016 I fixed turn signal problems by changing places of two wires white and dark green.
They are found in so called multifuction switch or with other words the component where you have hazard switch and turn signal switches.

There is also coming up to steering column from body harness 2 wires for horn ( light blue and black wires ).

Does somebody have good picture of this part ? If there is possibility to see how the white and dark green wires are placed.
It is so long time ago when I had problems with turn signals.
When uninstalled switc component could I see that I had soldered white and green wires. Originally all those wires are not soldered.


I have a picture ( bad quality ).Coulden`t attach because it is bigger than 1 MB. Link to image:
