Hi Joseph, my eMax has 3 fuses right near the battery. One is a 40amp which blew and caused the symptoms you have. I didn't realize the in-line fuse was there until they pointed it out.
Yes, the long story short, I would crank it a bit without the glow plugs coming on, stop cranking for a bit, then the plugs would come on. I think what would happen is introduction of cold air and cold fuel introduced to the engine cooled it enough to trick the plugs to come on.
Hi Brian, my dealer installed the inline on my eMax 25s and it works fine. I usually give it 20 minutes minimum but try to hit 40 minutes. At that point the cab heater starts quickly and the engine is smoother. Mine has the Daedong engine and is a bit cold blooded....
Sounds more like not enough current....battery connections or ground to tractor. Has the battery been changed in the 10 year ownership?
Joe, where it's cold and the snow is deep!!
