.I installed my temp gauge in November. As you know, it has been a brutally cold winter here. The temp gauge has never even gotten to 150F, even on a hundred mile trip. I am wondering if it is reading correctly. The directions for the gauge said to use an 18 gauge wire to connect the sender to the gauge. I didnt have any, so I used 14 gauge wire. I am wondering if this might make the gauge not read correctly due to the wire being thicker? More resistance in the thicker wire?...Any thoughts on this?
You're worried about nothing. The larger diameter wire is definitely not going to make any difference, because the difference in resistance between 14 and 18 gauge is almost zero. If it was me, I would put a piece of duct tape over the gauge and worry about something else.
BTW, bigger wire= less resistance.

Good point, I knew that...brain fade I just want to keep a good eye on the trans temp as I will be towing with it this summer.
Hey Harry, I would be more concerned about the temperature in the trailer's fridge. Nothing better than cracking a cold beer once you finally get to your destination.
