Ignition coil replacement

 This post has watched 3 videos on ignition coil replacement.   This was resorted to when diagnosis reveal:   there is enough fuel, there is no problem with fuel lines, and sparks do not show at spark plugs.   So the ignition coil could be defective.   The three instances were on:    zero turn hydraulic operated lawn mower, a walk behind lawn mower and a John Deere lawn mower.  The replacement is straight forward and easy,   The parts can be purchased from Amazon (Lazada too?)





Safety switches at John Deere tractor lawn mower

 It could be difficult to start a John Deere tractor lawn mower because of numerous safety switches:

       1.  Seat

       2.  Clutch pedal

       3.  PTO

       4.  Reverse

You cant start the machinery if any of the 4 are safety switches are on.  So be sure to make them closed switches so that you can operate them





Black smoke after replacing turbos and injector

 It could be due to the intercooler.   Signs of defective intercooler:   black soot and oil at the underside from the leak.
