[Amps] Automotive Relays

[Carl]

About the same way any antenna relay is handled; they work fine for years 
and then either replace or clean. With gold flash I guess it depends upon 
what is under it and how it takes to burnishing. It also happens to vacuum 
relays where reversing the 24V wires and/or temporarily running exciter 
power (aka barefoot) thru the receive side often restores them for long 
periods (years).
