I have a Bobcat t190 with a glowplug problem. They work perfect untill it gets around 60 degrees or lower outside they dont work witch is when you need them most. When i turn the key it will come up with the normal coundown from 19 seconds but then it stops counting down and the glowplug light blinks on the right pannel. The dealer has no idea what it could be. Thanks in advance for any help.
