Re: Burned out cooling fan. Possible short in wire?

I set the meter to beep if the circuit was completed. I'm not sure what that number measured. If the circuit was completed, the meter would beep and those numbers would be displayed. If the circuit was open, then I would get infinity / overload. Does that help?
The cable won't reach all the way down to the road. Also, scraping against the road would not turn the white connector black like this. There was definately some melting action going on here.

Wha??? You tested what? You didnt test the current, and I couldnt really tell you what you tested. Was the connector melted - or did it scrape against the road?
You have to check the schematic diagram and see what those connector pins do. --

Hey folks. I'm continuing my quest to stomp out electrical problems from my 944. (1990 944 S2)
So here's the deal: Driver's side fan is working fine (it comes on as soon as the car is started, but that's another issue). The other fan does not come on at all (not for cooling, A/C, etc). It didn't take me long to find out why. Upon crawling under the car, I saw that the rubber boot surrounding the connector for the second fan as well as the white plastic connector were partially melted.
Diagnostics with a voltimeter revealed that the second fan is burned out (no circuit completed). The cable that connects to the second fan tested fine (.502 reading versus .540 for the driver's side lead). The cable looks like a$$, but it's still passing current. So I guess the fuse for the second fan is good as well, right?
Naturally I'm going to have to replace that fan. Do I need to replace the wire too? Any idea what would cause the fan to short out like that?
