New Holland Lt190b track loader

[Rickftball]

Question for the pros.... New holland Lt190b starting issue. Intermittently will not start. Skid steer cranks fine, just won’t start, flip switch to service mode starts fine. I have checked the seat belt, seat sensor, and fuel solenoid **** off. The seat recognizes your are in it and seat belt light goes out when you buckle the seat belt. The solenoid at 12 dc volts to it. Machine starts right up in service mode. My question is, what does the service mode bypass in order for it to start right up? From what I have read on the forum it is just the seat/seat belt. For me to get it to work, I let the machine run in service mode for 30 minutes then I’m able to start it normally and works fine. Maybe something heats up and it works. Where can I go from here? Thanks

If you have an auxiliary circuit, make sure it is centered. On my C185 if the stick is not centered, it will not start but will crank. Don
