I had repeat trouble with this, had it"fixed" a few times. Finally, I was out in Shipshewanna, in a regular garage. They found my problem. Had to do with wire from fixture. He rewired, and instead of dropping belly pan, I have done a pretty ok job of running it to the front. Everything works fine now. It was one of those wierd situations and this mechanic just knew what to do to fix it.
