Mike Donohue Posted April 5, 2014 Share Posted April 5, 2014 Intermittent issue with a 2001 Vision with a 460/13 speed . Sometimes the dash works as it should , sometimes it will just shut down and show noting (although the VIP is still getting all the info and displaying properly) and other times it will be working ok, then the seat belt alarm light and bell goes off and at the same time all gauges swing back and forth. No sequence or regular timing , just like a moody lady ! Any thoughts would be greatly appreciated !

Macktech689 Posted April 5, 2014 Share Posted April 5, 2014 There is a ground connection behind the cluster on the left side just below the dash cluster opening, several wires on a small screw that has caused weird gauge problems.

Bobby j Posted April 5, 2014 Share Posted April 5, 2014 Also check the wire plugs that plug into the back of the circuit board any loose pins or metal contacts loose or burnt looking Quote Link to comment https://www.bigmacktrucks.com/topic/35305-dash-goes-on-off-and-the-seat-belt-warning-light-flashes-with-the-bell/#findComment-240756 Share on other sites More sharing options...

mackmechanic15 Posted April 18, 2014 Share Posted April 18, 2014 Grounds are a big thing for this and some were updated where u cut the ground and relocate to the ground circuit breaker on the firewall. Only thing is a tell tale sign the cluster itself is faulty is if customer complains the seatbelt light comes on. Probally doesnt even have seatbelt switches. Probally needs a cluster to fix this.

bbigrig Posted April 22, 2014 Share Posted April 22, 2014 Same here.....its usually the cluster's circuit boards if the seat belt light comes on. I think it was just shy of $450 Canadian last time I had to replace one a few years ago. Comes as an assembly just swap the gauges over.

Mike Donohue Posted April 22, 2014 Author Share Posted April 22, 2014 Thanks ! Just got it all apart yesterday and grounds were sound and I played around with the plug in and all seemed well there and nothing corroded or burnt.

thomastractorsvc Posted May 2, 2014 Share Posted May 2, 2014 did you read the service bulletin in the post before your last? You may need a new dash cluster, there were several fixes for this problem from replacing it to a changing the ground. Quote Robert"I reject your reality and substitute my own."
