1520 glow plugs

[nh1520]

With 600 hours on the meter, just tonight I noticed that my dash light for the glow plug will not go out. It lights up fine and starts the tractor quickly - but no matter how long I hold the key back to the "glow" position the dash light doesn't go out. When I release the key from the glow position and start the tractor the light goes out just fine. Any suggestions as to what the problem could be? Thanks!

I guess I solved my own problem as the light is going out now. I had CAREFULLY powerwashed under the hood the other night and no doubt sprayed something that I shouldn't have. Not careful enough I guess. After sitting overnight - its working OK. I just thought I reply back since there were 36 views to my question.
