Tach... MK2 Motometer on a MK4 TDI alternator
« on: November 27, 2007, 06:29:43 pm »
Hi,

I have a '03 ALH TDI into a '92 Jetta (it was a 1.6TD)

I want to use the stock MK2 cluster, but it indicates ~1100 instead of 900rpm at idle.

As I know, the input is a 0-12v signal. The frequency is wrong for my cluster (reading 903rpm on the vag-com, it's electronic TDI, not a M-TDI)

Is there any solution?

Thanks
