Mass is the body of the vehicle, which acts as a negative terminal (-). At least here in Spain.
I hope to clarify doubts.

[rickf]

Ok, Ground is what I was thinking the problem may be and his description kind of pointed there.

[rupert's]

Sometimes I forget to be careful with the translator: lol:: lol: Yes, ground, ground, negative pole. It is the same, in Spain they say mass and I did not think of the translator.

In the end the bulbs were all good, as I said above, the headlights of the front and rear turn signals (pilots) have 2 different negatives, one for the bulbs and one for the blackout lights. I upload an image.

Negative 1 had electricity and negative 2 had no electricity, they are not connected to each other because that black ball isolates them, it is silly but it makes you lose time.
Cables 1 and 2 end in the screws that hold the headlight, my car is sandblasted and then primed, so some screws do not make contact, I had to sand a bit.
I don't know if I explain myself.

The circuits are to operate independently of each other is how I understand the circuitry of it.

[Redlight]

Now it makes sense. thank you for clarifying the message. no ground no light.
thanks

Explanation is perfect. If you are testing the ground terminal and it shows voltage then between the terminal and ground then the ground point itself is bad and that is why the light is lot working. Since you have the cover off of the light you can make a jumper wire and clip it to a good ground and then touch it to the ground terminal inside the light and see if the light comes on. If it is a bad ground connection this will bypass that and the light will work. Make sure you are touching the right wire! I always just tap it at first, if is is not the ground but it is the power wire you will get a healthy spark but a quick tap will do not damage. On the ground side you may get a tiny spark from the regular bulb and no spark from the LED bulbs.

I try not to modify the route of any cable, I think I no longer have any electrical problems, everything seems to work correctly. I have only seen at the last minute that the brake lights are on as long as I step on the brake the brake lights go out, they are working in reverse.

I saw it just before I left and did not have time to look for the problem, I think I have connected the two wires of the switch behind the brake pedal incorrectly, if this is so, I just have to change the connection and I am done with electricity. (I hope)

[rickf]

The switch is either on or off, wires do not make a difference. You have the switch mounted so that it is touching the wrong side of the pedal arm. If I remember correctly the switch should be activated when the pedal is released and when you push down on the pedal the switch is released. It works in reverse of what you would normally think.

[Horst]

Rick,
Switch works in the normal manner, pedal pressed - switch closes.

[rickf]

Ok, I could have sworn I saw somewhere that there was major confusion due to the fact that the fact that the switch worked in reverse but I don't have an A2 so I don't have a reference. Either way it is still a DC circuit so it is on and off, wire position will not make a difference.

[Horst]

Correct, it is simply a switch. No matter what current goes thru it, wire orientation does not make a difference.

carnal knowledge! you know everything! you are made some machines! Knowing this, this weekend I am going "to shot made" I turn it around and to something else! Thank you for sharing your wisdom with me.

From the -20 manual, unfortunately the picture is impossible to see.

When ever stoplight switch has been
removed, detached, or disturbed in any
way, a brake pedal free travel adjustment
should be made.
( I) Turn eccentric adjusting bolt (fig. 2-283 1
until brake pedal has approximately 1 / 4” free
play. .
(2) Check stoplight while brake pedal rests up
against stop.
(3) If stoplight is on, turn rod nut (fig. 2-283)
until stoplight goes off.
NOTE
Approximately 21/2 to 31/2 clockwise turns
of the rod nut should be sufficient for
proper stoplight adjustment.

[rickf]

Download this manual and go to page 8-46 and it will show you exactly how that switch is supposed to be put in there.

Said and done! I changed the position of the switch, adjust the light start with the nut and go! I avoided several laps thanks to your advice!

I have a question about the lights, I will try to explain it thinking about the translator ...
When I turn on the dipped headlights, the turn signal lights (yellow) also turn on with the fixed light and if I operate the turn signal switch, this yellow headlight has to have a fixed light on and another flashing, is this so? Or do I have another electrical problem? I checked all the connections and they are all good, although I have doubts because it is a bit strange to go with these yellow lights on
The position of the light switch in SEP DRIVE and OFF
