I found out that if I disconnect the wire at the ignition module that goes to the external cutoff switch it will start - but then I can't shut it off (unless I reconnect that wire). Switch is not defective (checked with ohm meter).<br /><br />CDI ignition module was replaced 3 years ago. Engine has been run maybe 30 minutes since (motor is just a backup motor). It started up last year, but refused to start this time.<br /><br />I replaced the rectifier (some test told me to do that), still no change.<br /><br />I suppose the ignition module could be defective again, but is there anything else that could duplicate this problem so I can save $130?<br /><br />Thanks
