Kubota L2900 gst glowplugs not working

[ronmorr]

I have a kubota l2900 gst the glowplug light used to come on and off after the tractor was warmed up now not comming on at all. I have no power to glowplugs. I have replaced the glowplug controller have power out of the relay and the temp. sensor seems to be working ok. Any one have any suggestions?

I don't have a Kubota, but I'd first check the relay. They are prone to failure and a lot easier to swap out than the plugs.
