Kubota KX-040-4 Relay Question

[dpauly]

Greetings. In the Fuze Box located inside the cab (under the seat behind the lockable panel) of my 2019 KX-040 there are 10 Relays: one of which (the hardest to reach of course) is physically larger than the rest and identified as 'Power' on the box cover label. Can anyone tell me the specifics of this relay i.e. part #/ordering info; which particular circuit(s) it is part of; etc.? Unfortunately, in trying to check if this relay is working I destroyed the outer case while trying to get it out so any info that may have been visible is no longer (though the info on the other relays is very difficult to read as well.) Another question: anyone know a suitable substance to coat Relay & Fuze 'blades' with to prevent future difficult removal (if I'm correct, Dielectric Grease is actually an insulator of sorts thus would not be a good choice, imo.) Thanks in advance.

OK, Dielectric Grease seems to be the stuff to use/not to use depending on who you believe. Various automotive blogs have comments & user experiences at either end of the spectrum. Seems some folks have had relay failure they attribute to the use of Dielectric and other greases migrating from the blades to the contact(s) inside the relay housing. On the other hand, some users swear by it.

You should be able to get a replacement relay from Kubota or an on-line vendor. Kobuta's PN is RD451-54210.

Dielectric grease is what you want. It is an insulator, which is counterintuitive, but the contacts wipe the contact area clear, and the grease basically entombs the contacts to keep out moisture.
