cq, my stop engine circuit has a toggle switch. The lanyard has been lost. The problem is the switch is intermittent and one must constantly switch it off and on while cranking the engine, until the engine fires and it will generally start on the first turn of the key every time that day. It seems the problem exist when the engine is off for a short period of time (about an hour or more). This is on a '96 Tracker Nitro 160 TF with a '98 Mercury 90 for the engine. The switch is an integral part of the Engine Remote controls.
