Should one use dielectric grease on motorcycle relays?

If it is not exposed to elements do not use the grease.

I am not an engineer nor did I stay at a holiday inn express last night, however, I spent 12 years fixing electronics for the Navy, and can tell you that corrosion is not your friend.

Use it. It keeps any environmentals out of the connections - moisture, dirt, whatever.

It attracts dust and dust absorbs moisture. So if it is not exposed directly to water do not use it.

Oil (grease) and water REPEL each other.

How in God's name would dielectric GREASE "absorb moisture"??

Following that, if it "absorbs moisture", WHY would you use it on something that is "exposed directly to water"??? Water IS moisture, after all....

Dust may absorb moisture, but the dust would be on the surface of the grease, not in contact with the metal. I do not know about your Buells, but none of
mine have sealed electrical connectors, which means the connectors are always in the presence of moisture, even if it is just humidity.

If it keeps the mud out, it's good.

To be clear, I wouldn't fill a relay box with grease, but to seal the external connections, yes.
