Dead tacho.

[magnusfeuer]

Hello,

 

A good while back now, I upgraded my 2002 SV from the stock Zetec ECU to a Pectel T6 unit (from Pi) together with a new harness.

 

Everything went fine apart from the annoying fact that the tacho died. The control-lights (high beam, etc) are still operational, but that's it.

 

The signal gets all its way to the tacho, so that problem is out of the way.

 

When I remove the gauge and pop the rubber plug, I am not greeted with the expected 6 dip switches, but rather a single plastic protusion that has two metal leads in its sides. I've dabbed a bit with electornics, but cannot for my life figure out what this is.

 

The connector has 8 pins arranged in a 4x2 pattern.

 

Caerbont, who manufactured the unit according to a sticker on it, could not provide any help on their website.

 

Three questions:

1. Is it possible to configure this tacho at all for different signals?

 

2. Does anyone have the pin configuration for the 8 pin connector?

 

3. What's up with the little plastic thingy under the rubber plug?

 

Thanks!
