T5 105 won稚 start

[RJKTVR]

Hi, suddenly I have starting issues, the tractor won稚 start. checked the seat switch, the PTO light was one but that was the plug on the connector, handbrake switch works ok, not sure how to check the forward / reverse lever switch ? When the ignition is on it痴 constantly bleeping , have checked everywhere else I can see for damaged wire, blown fuses etc. It痴 a 64 plate tractor with 900 hours so hasn稚 had a hard life. Any thoughts on what to check next ? Many thanks
