Yamaha 2005 Kodiak 400 Starting Issues

[Bobby_Rickard]

Replaced battery, relay and starter. Turns over and starts part of the time and other times just rapid clicking.

Not sure if you found an answer to this but if all the starting components are new and the battery is strong I would think there are some bad connections. Clean up the connections and don't use dielectric on the connections either.

Why wouldn't he use dielectric grease on the connections? This is the first I have heard of this.  How would you clean up a connection that is surrounded  in a plastic housing?

Dielectric is non-conductive so it should not be used on a connection. Over a connection (after the connection is made) is fine but that can attract more dirt and grime as well. To prove this, take a multimeter and check continuity from either side of a small glob of dielectric grease. Dielectric is great for use on waterproofing seals on connectors. It also helps keep the rubber soft and aids in disconnecting the connector the next time too.

I would have to look at the connector to decide how to clean it. Sometimes you can get by with just some electronic spray. Sometimes you may need to replace the terminal(s). Sometimes you can scrape of corrosion with a pick or small screwdriver.
