    once was pto switch, once was pigtail connector engine harness to frame harness loose. cutting today,stalled out. cranks fine,wont start. has weak to no spark. looking for ideas. fuses good, battery power from ignition switch to engine harness,fuel solenoid powered. i think i have something going on in the interlock system. tested seat switch,both handle switches, and park brake switch. all check good. scag corp no help trying to get a shop manual,and local scag dealers wont give up info, want me to bring machine to them. any help would be greatly appreciated

    Might be another PTO switch... Some scags eat PTO switches , If it is , check wiring for melted connectors or loose connections., The safety system uses the PTO switch .

    To bypass the safeties (TEMPORARILY) Disconnect the white wire that goes to the engine, at the pigtail on the engine, The engine will take about 3 sec to shut off with this wire disconnected.
