Hi People, had to work on gearbox so removed seat. Want to start tractor without replacing seat. Have closed all pressure(safety) switches and new battery. Fuel pump, Fuel & temp gauges, LR indicators, and glow plug indicators light up but not starting. I understand the reasons why this is not recommended for safety reasons but I don’t want to assemble everything to discover I have a problem. Forgot to mention have also filled gearbox with new oil. Any clues on what I’ve missed gratefully accepted. Cheers Q
