Found a site Relay Wiring that details how to wire lights to work either automatically with high or low beams, or independently, when a ON-OFF-ON switch is used. My confusion is this: The author of this article spec'd the wire gauges to be used in his first diagram: Then, when diagramming the 3 position switch, he uses an 18 gauge wire spliced to the 20 amp fused power wire going to terminal 30 on the relay: Seems to me that the 18 gauge wire going to that switch has 1) too small a wire and 2) too much current for the switch, uless the switch itself is rated for 20-30 amps (which isn't spec'd, but I would use in this configuration). Now, am I missing something basic here? Shouldn't that 18 gauge wire be larger (like 12-14 awg)? /forums/images/graemlins/ears.gif /forums/images/graemlins/ears.gif /forums/images/graemlins/ears.gif TIA!
