FWIW, my experience with relay hunting/chatter has been when re-wiring a 
LandRover (which didn't have such things in the original design).

The hunting (more of a whistle than a chatter sometimes) occured when a 
heavy load had dragged the battery voltage down.

So - are those relays really getting enough 'juice'?  If the 
hunting/chatter occurs often enough, why not put a voltmeter across the 
relay solenoid and see if there is any change in the applied voltage (power 
fluctuations?) when the hunting occurs.

Cheers
