hey guys I just joined and love the form. I have a m7040 with cab and the radio isn't working. I can see that it is on but can't get any sound do you think the outputs are dead or is there something else that needs to be adjusted. This is the first cab tractor I have had. Also the head lights have a short some where and I just wanted to see if this is common on these tractors it is a 2007 but only has 300 hours on it seems odd to have a short already but when I replace the fuse and turn the headlights on it blows right away. Thanks for any help
