DCC question

I would contact Mr. Baskin. Good luck.

HMMM....Sounds very similar to issues I had with my first DCC. I didn't personally hook the first one up, and I felt it was too close to a heat source. It seemed to work here and there, but I constantly found myself under the hood and tinkering with jumpers to try and find a good setting. It never happened and the unit pretty much croaked on me within 6 months. I did, though, purchase a new one and relocated it to what I felt was a better location, near the battery. I also purchased the remote temp controller so I could control the fan temp from within the car (I also recommend purchasing the LED light for inside the car to monitor the controller output). Since I re-did the setup like this, I have had absolutely no issues keeping the car cool. Perhaps your controller or temp sensor is defective.
