Electric Relay Advice

[QUOTE="67Dart273,
Those diodes are intended to reduce "inductive kick" from the relay coil, "spike supressors."[/QUOTE]

Hello 67Dart273,
Great explanation for Diodes on relays to control inductive kick (Flyback Voltage)
Also a relay can have an added resistance across the coil (as depicted in pix) in addition to the natural coil resistance.
Depending on the application they may use a Zener Diode instead of a traditional type Diode to customize the specific application.
There are numerous types Transient Voltage Suppressors (TVS) and MOV's that can be used.
Happy Mopar:)
