Hi everyone I am from the UK and recently traded my 2003 6300 in for an 05 6420s.
I bought the tractor with a starting issue that the seller sorted out. The glow plug light was flashing with the warning light and the tractor really struggled to start. He fixed the issue and said it was the crank sensor, he replaced with a new one and gave the tractor a service.
Today has been my first day I have used it properly and started hauling.
The same warning lights have come up again, the tractor starts but not immediately. I don't think the battery is much good anymore.
Does anyone have any ideas to what this could be?
