Electrical issues starting shutting off

[Kish318420]

Sounds like the switches need adjustment as in their position to engage and disengage, or the switch contacts need cleaning because of corrosion. As a last resort switch replacement, just have to to the bad on(s). A process of elimination that has to happen.

Seems like your onto the problem.
If the hour meter is running when the key switch is "off", it's hard to imagine that a safety switch is the problem.
It would be a good guess that the switch isn't working correctly, wires or terminals at switch are shorting, or switch is miswired.

Usually the hour meters will stay 'on' but are not running until the engine is running. Once running, the hour meter will display a small hour glass. If there is no hour glass showing, it's illuminated to show the hours but not running.

Is there any access too wire diagrams

Undoubtedly diagrams are available but this is always a busy time of year. Be patient,someone will eventually find time to track them down for you.

Are there relays in the safety circuit? If yes, they may be sticking or bad contacts inside or in the connector.

Try the cheap stuff first, the safety switches might be most the same, buy one and start eliminating.
If the problem is intermittent, than that's the way to go.
