bluelinehiway 8 #1 Posted July 28, 2019 Can anyone help with identifying the relay on a 1986 310-8? The low oil switch runs through it and apparently it must be toast as I'm not getting any clicking sounds or meter readings thru it at startup. The durn thing in my tractor has no ID markings for me to replicate the relay. Thanks in advance. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,478 #2 Posted July 28, 2019 See if this helps. Click on the pictures. In 1986 if the oil level is OK the relay is not activated. If you can remove the oil level switch wiring from the circuit it would give the same result. Oil level low the relay is activated and the power to the starter is interrupted. There are special instructions to remove the oil level switch from the engine without damage. They are no longer available from Kohler.

FarmerJon 16 #3 Posted February 1, 2023 How would a person test that oil level relay? My volts going I to it are 13 but coming out to the solenoid is 1.7. My continuity seems fine on the two prongs though. Very confused. 1 Share this post Link to post Share on other sites
953 nut 51,511 #4 Posted February 2, 2023 (edited) @FarmerJon Your question will get a lot more attention if you start your own thread. Just click on this link https://www.wheelhorseforum.com/forum/65-wheel-horse-electrical/ and then click Start A New Topic and you can ask the question to the whole bunch of us. Please tell us the model number of the tractor you have and what has been done so far. Edited February 2, 2023 by 953 nut fat finger 1 Share this post Link to post Share on other sites

My volts going I to it are 13 but coming out to the solenoid is 1.7. My continuity seems fine on the two prongs though. Very confused. Your relay has 4 terminals. 2 for the relay coil ( 12 volt power and ground) and 2 to activate the internal contact (12 volt power and to solenoid) When cranking if you oil switch is made, power comes from that switch to one side of the relay coil. if the relay ground circuit is good (through the other coil wire) the coil is now energized. (click) Power is also coming from the key switch, neutral switch, PTO switch ect to the 3rd terminal (one side of contact) With the coil now energized the magnetic field of the coil closes the contact. Power now flows from one side of the contact to the other and out to the solenoid. "My volts going I to it are 13 but coming out to the solenoid is 1.7." Sounds like the relay contacts are not closing or are burnt Edited February 2, 2023 by squonk 1 Share this post Link to post Share on other sites
squonk 38,844 #6 Posted February 2, 2023 This is not you relay but the concept is the same. The" low current" is the oil switch circuit. High current is the solenoid circuit 1 Share this post Link to post Share on other sites
