Porsche 944 sp1 owners guide

So,

Now that I figured I was over all this, but the fans never turn off now. Just turning the key without starting it turns on the fans. I checked the fan relay again and that aint it and I can't find any shorts so it looks like the fan switch is busted. I'm not sure how to test the fan switch but I ordered one today for 11 bucks so worst case, I have a spare. I'm compare it electrically with the current one to see if it's ok.

I replaced the fuel sender with the replacement one today and the whole job took around 20 minutes. I took photographs which can be seen here. The gauge works fine now and finally I can tell how much fuel I have in the tank. The replacement fuel sender cost 44 bucks for a used one. A new one seems to be around 170 bucks. I like this 944 as the parts are cheap and I can work on it myself which saves on labor. Next up today is an oil change with new filter too.

Tim delivered the car with the fuel guage not working. He's tried to debug it but got no where. I figured it out this morning. It's the fuel tank sensor. It was pretty easy to figure out. There is a black square cube connector on top of the fuel tank and you unplug that. Two of the wires connect to a potentiometer in the tank which reads between 65 ohms and 3ohms. 3 is full. I did a quick check and the gas guage went to full when I put a 2.5ohm resistor across wires 1 and 3 in the connector. Now, I gotta replace the fuel tank parts.
