Care to explain?
You modified the board as per original instructions AND replaced voltage stabilizer, OR just replaced voltage stabilizer and that made it work?
Sorry and thanks.

If you are stuck there, I question whether or not you should be attempting the conversion.
De-solder the two wires noting their color/location. Lift off the circuit board.

Has anybody modified this board to make it work? the circuit is different, but not too much different than the other boards mentioned in this post. Still cant figure out how to covert it though. I have a schematic drawn out if anyone wants to see that but it isn't the prettiest drawing

I just got a mk1 tach swapped over in my '79 rabbit. Along with replacing the appropriate tachometer components I also had to add the W-terminal to the alt also as the alt didn't have one. It works great.

You'll have to trace out your board (front and back) but they are all basically the same schematic and require the same replacement items.

Can't believe this thread is still running, only popped in to borrow the pic links but thought they may have been ruined by photobucket.
Use chrome browser and apply the photobucket fix and all the pictures reappear - if anyone does want the originals please email me regcheeseman AT btinternet DOT com

83 Rabbit LS with a 1.6TD
I was wondering if anyone has come across the tach needle not moving at all when done the conversion? I have followed the board changes, got confirmation that I have 8v AC from the W terminal.
Traced the line from the Alternator to pin #5 on the 18 pin connector that plugs into the cluster and have continuity thru said line. Traced the pin# 5 on the back of the circuit sheet which goes to what I'm 99% sure is the Signal post on the tach circuit board. ( I used the 83 GTI circuit sheet ) ** Is this my mistake? ** looking at them all I see is that the 2 circuits that went to the clock back were cut at the factory on the GTI one.
The cluster has power ( lights, fuel and temp gauges work ). Next step is to take apart and triple check my circuit board work.

Silly question but did you run a line from the W terminal on your alternator to the signal input on the cluster?

Yes ran a line from the 'W" terminal to the non used pin#5 line which is the tach signal. confirmed voltage and continuity all the way up to the cluster. Might be the voltage/tach stabilizer guess ill have to meter that as the needle does not move at all. Just curious if everyone keeps there stock circuit sheet or use the GTI one.
