Engine cutting off when brake/clutch pedal released
I have a Murray riding mower model 46503X8.
I depress the clutch brake pedal to start the engine. The engine starts easily and runs when the brake/clutch switch is depressed.
If I release the brake/clutch switch the engine shuts down. I replaced the brake /clutch switch and the pto switch, but the problem did not go away.
I did the following test. With the engine running and the brake /clutch switch depress, I engaged the cutting blades (pto switch) and the engine shuts down.
I have an electrical diagram but need help to solve this problem.
