no start Kubota T1670

[tidentenn]

NO spark (plug not wet)
NO power to +12VDC wire going to carb while cranking
Seat Switch tested OK
Check all 3 fuses for continuity- OK

This is my MIL's unit. I see where there is a safety switch on the brake ( K1122-62250 )
Does this switch kill voltage to the coil and the carb?
Where could I find a schematic? I struck out with google.
Many Thanks guys!

Dunno, but a temporary jumper across a safety switch is a great diagnostic tool. Multiple safety switches? Multiple jumpers. All of them.

Once you get it started, you can remove them one by one to see where the problem is. OR you will find out it's not one of the safety switches and move on to other possibilities.
