The fan I replaced the old one with has a higher capacity than the TM original. It is indeed pointed in the right direction and the polarity of the wires is correct. The input screen on bottom of TM and output at end of dryer hose is clear. The alternator and battery in my Tow Vehicle appear to be working properly but I will get out my VOM and check it out. I have noticed only a yellow light on the battery panel. This may be my problem. My TM batteries could be newer but they hold a charge. I rarely if ever hook up to shore power when I'm camping but I have a solar panel and controller I keep the batteries topped off with. I have run with both DC and propane while driving with same result. Time for more troubleshooting.
Thanks
