Dead cluster in early series ford E450 super duty.
My instrument cluster and other things have gone dead twice on my 2006 E450 SD. I think the first thing to happen was when I installed a new battery. The second thing was when I removed the negative connection. Took it to a Ford delearship and it cost lots of money and did not work. Never, ever take an electrical problem to a dealer.
I have researched it for hours and found many things to cause this. A bad relay, a short in the gear selector, etc.
If you have had this problem, i would sure love to here your experience.
