Tough Cold Starting

[leenigen]

I think the controller is working okay. The light comes on for probably about 15-25 seconds. I have had other problems with the controller that may be related. It burnt up twice in the last year. The coil in the controler was shorting. When I ripped it apart to see there was black spot on the coil that smelled burnt. After the second time I checked the glow plugs and found two bad ones. After replacing all the plugs and controler, I haven't had a problem with it burning out since.
