Re: [DML] fans run continuously, strange wiring

[Todd Masinelli <tmasin@xxxx>]

I don't mean to beat a dead horse here with another question about the
cooling system, but as a new owner I'm really interested to learn what's
going on with my car and if it's normal (or at least not that bad).

After a recent overheating situation, my fans have been running
constantly...so, per the list's suggestion, I pulled one of the otterstat
wires and the fans stopped. Plugged the wire back in and the fans started
back up. Okay, so now I know my otterstat is bad and I'll be replacing it
soon.

One issue still remains, though. After my fans were running for a while, I
reached into the relay compartment to feel for heat. The fan fail jumper
was a little warm, as was the #112 fan relay (which I just replaced). I
felt the N/O wire leading to the 40 amp breaker and it was cool, as was the
metal holding the breaker in place. However, the B/O wire (which the wiring
diagram says should be N/S) was blazing hot. The plastic shroud covering
the spade connection was hot enough to leave a red mark on my thumb.

What's the deal here? That wire leads from the fan fail jumper to the
cooling fan breaker, right? So between those two the wire is building up
resistance that somehow isn't being felt by the breaker or the other wire
leading from the breaker? I don't understand.

Is there even a problem here? If so, is it something that my eventual
purchase of a Fanzilla will fix?

Trying to learn and grateful for help,
