Gauge Power problems

[WhiteKnight]

Hello Guys,

I have HFS-3 system installed on my Porsche 997tt.

The problem is;

The system is working and i have 5-6 bars of flow, but while going WOT, sometimes gauge loses power and it comes back very quickly in about half seconds.

It goes off and on again 2-3times during a 60 to 270km run.

What can be the cause?

My findings;

- Take of the plug of WATER LEVER sensor.
- Seperate the BLACK/WHITE grounds from each other.
- Check the resistance of the grounds.
- Check WL AND WH. (I have already set them to the limits. WL 7 o'clock, WH 5 o'clock, so i dont think that im reaching the failsafe)


Anymore ideas?

Thanks,
Emre
