GRA Installation Successful: Thanks Forum!

Hello dear participants,

I posted a while ago that I wanted to upgrade the graphics card (GPU) in my G3 1Z.

This weekend, the time finally came.

I found the circuit diagram here (it's probably very well known to those interested in the topic).
http://www.vw-dreams.de/GRANACHRUESTUNG/gra.html

As a 4-pin connector, I chose the "budget" option using "used" pins and hot glue. It worked great.

I purchased the following switches from Conrad: 1x SPDT switch (normally open/normally closed), 1x "changeover pushbutton" (normally open)/normally closed/(normally open) (it has the same construction as a switch, but functions like a pushbutton, returning to its default position when released).

Toggle switch for on/off, and a rocker button for resume (press up) and set (press down).

The entire unit is mounted under a blind cover next to the recirculation switch, below the heating switches, making it conveniently accessible from the switch lever. I've also installed two LEDs that indicate the switching status (green = GRA off, yellow = GRA active - yellow like a warning), and they also help guide the way in the dark.

Everything was carefully soldered and insulated.

Today, I went to the friendly staff and had the GRA activated, also making a donation to the coffee fund. They actually asked me for the "brochure with the CODE number." Of course, I had the printout from the website mentioned above with me, along with the instructions, so it was done in a flash.

Dann ab in die Garage, alles sauber installiert, noch fix die Masse vom Zigarettenanzünder gestohlen für die LEDs (ich liebe diese kleinen blauen Stromdiebe, bei niederen Strömen wie für meine LEDs das einfachste überhaupt) und ab auf die Piste. Und Immediate success.

Conclusion: A great value at 8 EUR plus the cost of coffee, finally a chance to enjoy some soldering and crafting, and the good feeling of having accomplished something.

Here's a picture before installation:


Also recht herzlichen Dank an Euch, besonders natürlich an Thomas aka. Necrite.

Best regards,

Eric.

The link is from elsewhere, and Necrite wrote 11 posts years ago.

Are you sure you haven't answered in the wrong forum ?

The term "billisch" is familiar to me . I actually used it years ago, to describe something that was too... well... for the GRA:

Hello,

You're right, the cheaper version actually came from somewhere else (from you).

I got the link from the forum.
/viewtopic.php?t=7112&highlight=gra
respectively / or rather / that is to say
/viewtopic.php?t=11011&highlight=gra

Okay, so it wasn't completely wrong after all. I also found the link to the circuit diagram here, but I can't remember where exactly.

So, a special thank you to you and the other person who contributed ideas, whom I can't seem to find now. I've really only been searching here.

Nice days.

Eric.

Sorry

That's not what I meant. I didn't want to beg for personal recognition.
Mainly, we're glad we could help you and that your Trekker GRAt is running smoothly.
