I have a 2002 new holland ls 180. When I sit in seat- no action on the control panel. When I turn key once- beeps but still no lights. when I turn key to start it fires up but when i release key- it stalls and starter is still cranking for 5 seconds or so and then stops. I'm guesiing it might be a starter relay but I don't know why the control panel won't light up when in seat. Before this problem It always lit up as soon as i sat down even with key in off position. Does anybody have answers?
