Tractor Repair: Kubota B7200 wont start, auto electrician, gauge works

Question
I have a 1980's Kubota B7200 HST 4WD that died.  Battery strength is good.  No sound when key is turned.  Fuel gauge works but no lights or rear blinkers.  I replaced the safety switch once but I can't remember if that switch is supposed to have a noise when it is engaged.  I hear no click now.  I do own a small electrical multimeter but I'm no electrical whiz.  The tractor was running fine right before this instant death. Ehere do I start?  Thanks for any help.

Answer
David you could join the 2 wires on the safety switch just to check to see if it is the problem then replace it if this is the problem.

DAVID THIS IS ONLY A TEST NOT A FIX SO IF THE SWITCH IS FAULTY REPLACE IT AND THEN USE THE TRACTOR.

Hope this helps out the other item to check is the small wire on the solinoide is in place short of this I feel an auto electrician is needed.
