I'm looking into getting a GPS lightbar to use, and had the thought: will it work OK with a gas tractor? I know that they used to put resistor plugs in them and a capacitor near the alternator for radio interference if you had a fender mounted radio, will I have do do something similar to mount a lightbar on my 656 gas? Just wondering, if I get it, I'll be using it on probably 2 tractors, my 806 diesel and the aforementioned 656. I don't know anybody with a gps on a gas tractor- I guess most people using a gas tractor wouldn't think of gps! Oh well, problems of a young guy I suppose. LOL! -Andy
