subvet720 179 #1 Posted August 13, 2022 My son keeps asking me, and I keep answering him with an "I don't know". When this tractor was repainted many years ago, many of the items that were deemed non-essential were not reconnected. Being a good military man, I can't stand having a switch that doesn't launch, move or light something. Any assistance will be appreciated. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,046 #2 Posted August 13, 2022 The test switch simply tests the engine oil bulb to make sure it works. The oil lamps are the only ones that flash for those that have more lamps. The low oil switch is a float switch that monitors the oil level. If it is energized it powers a relay that then prevents the starter from working. That also lights the low oil lamp so you know the reason for the no start. The next time you change oil and the oil is drained try to start it and see if it works. If it does start shut it off immediately and make repairs. 3 1 1 Share this post Link to post Share on other sites
