S2 aby, mfts f76

[CQ20VTurbo]

Hello everyone,

I need to dig up a very old thread about the MTFS F76:

+ - Voltage supply, term. 15a (battery voltage)
C - Actuation of coolant temperature warning lamp (overheating) (termoswitch)
R - Air conditioner safety shutdown (termoswitch)
T - Actuation of coolant temperature gauge (9,8 ... 10.4 V from dash)

It's about thread #6 and the information above, in the following, LINK =>
https://www.s2forum.com/forum/techni...rs#post2155290


In my case, the ABY engine is installed in the CoupeQuattro Type 85.
After a long search, I found some important information about the F76 here in the forum, - but a few questions remain.

What exactly is connected to PIN 1/T on the ABY F76, and what potential is there?

• Ground
• or
• +9.6-10.4V?

Where does the voltage come from, where is it provided ?

• Does the voltage come from the Minicheck / KI ?
• or
• is it provided internally by the F76, and then simply passed through to the Minicheck / KI via PIN 1/T ?

After all, the F76 already receives +12V from Si 12 via PIN 3/+. It's conceivable that it converts this to +9.6V-10.4V.
But I'm not sure...


Perhaps you can help me with the information I need?
