I have a 3710 with less than 400 hours, normally the glow plug indicator lights for about 5 seconds first start of a warm day. The other day it stayed on for about 15 seconds, even though it was above 80 degrees. A little while later while mowing I noticed the indicator light was on with the engine running and warm. I shut it down and restarted, the light stay out. Now the glow plug indicater seems to come on randomly while the engine is running and fully warmed up! I disconnected the glow plug lead in fear of burning the glow plugs out. Anybody got any ideas why this would be happening and how to fix?
