Reply to "Diodes in cooling fan feeds"

marlinjackThe Machinist #5723 AMARGOSA MACHINE 'Running on Empty- Middle of Nowhere'

...That's correct! Especially if Your running Meriya Fans as, I am!! When You (try to) shut the Engine off, 'they' then become Two Massive DC generators that feed Current to the Ignition System, still providing Spark; The Engine will run on for 15-20 seconds until the 'Generators' come to a complete stop. The Diodes prevent this. OR You can Disconnect the fans and ignition from the Ignition Switch,(The Point at which the Ignition System connects to the Fan Curcuit!) and run them through there own curcuits using relays. I also make sure I shut the Fans off (Manually) Before I 'Kill' the Engine!...
