I have a dodge ram 1500. I have changed the radio from stock to a Kenwood. The initial installation worked fine and the radio came on. Now, I unhooked it to put the dash kit in and now the radio will not work. I have tried another radio as well and it does not work. I believe the problem to lie with in the truck. Any suggestions?

Check all under-dash and under-hood fuses with a test light or multimeter. Here's how:

Before doing any electrical work on your truck, always disconnect the negative battery cable first.
