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

The first thing I think off is the anti-backout tab of the RJ connector. Try bending it out manually until it is arount 45 degress from the horzontal. Do it for both ends. If the gauge is insde a tubular pod holder, it tends to press on the tab.

I would try this. I don't think it is a fault trigger from the electronics.

Dear Richard,

I tried bending the anti-backout tab of the gauge, but it didnt help. However i havent tried the controller side.

Here is a quick video of the gauge during full throttle run.

By the way, water level sensor is disconnected in this run to make sure that this fault is not related with it.

I'm really pissed off, i hope you can help

Thanks
