Gauges sweeping

[swalley]

If it's running bad, I could see the sweeping.
Are the gauges fine when the tractor runs fine?
I'd start by addressing the running bad situation.

bczoom the tractor runs like a champ until it starts feeling like a small miss then starts the sweeping and dash lights come on like you see when first starting does that make sense sir

bczoom it runs good for about 10 minutes or so before it does this the first time

Just guessing here, but "running bad" and gauges acting up at the same time. I have no specifics for what the problem might be, but with a common rail fuel system I'm sure steady system voltage is required. I'm betting you have a power connection or ground issue somewhere.

Thanks Fedup that’s what I’m thinking too but having trouble finding a wiring diagram to find all grounds I’ll just start at one end a go from there.
